using a hardcoded value later on.
Added a helper function that returns the observed values for
max_entries and max_size for each cli_samr_query_dispinfo() call.
These values were obtained from watching the NT4 user manager
application with ethereal and are the only ones that can enumerate a
60k user domain reliably under Windows 2000.
calls to init_unistr2() in the code and every one of them got the 3rd
argument incorrect, so I thought it best just to remove the argument.
The incorrect usage was caused by callers using strlen() to determine
the length of the string. The 3rd argument to init_unistr2() was
supposed to be the character length, not the byte length of the
string, so for non-english this could come out wrong.
I also removed the bogus 'always allocate at least 256 bytes'
hack. There may be some code that relies on this, but if there is then
the code is broken and needs fixing.
principal similar to the existing cli_lsa_enum_privsaccount() call,
except that cli_lsa_enum_account_rights() doesn't require a call to
open_account first. There is also the minor matter that
cli_lsa_enum_account_rights() works whereas
cli_lsa_enum_privsaccount() doesn't!
this call can be used to find what privileges an account or group
has. This is a first step towards proper privileges support in Samba.
1. reboot in parse_reg and cli_reg was shadowing a definition on FreeBSD
4.3 from system includes.
2. Added a bit of const to places.
3. Made sure internal functions were declared where needed.
This patch makes Samba compile cleanly with -Wwrite-strings.
- That is, all string literals are marked as 'const'. These strings are
always read only, this just marks them as such for passing to other functions.
What is most supprising is that I didn't need to change more than a few lines of code (all
in 'net', which got a small cleanup of net.h and extern variables). The rest
is just adding a lot of 'const'.
As far as I can tell, I have not added any new warnings - apart from making all
of tdbutil.c's function const (so they warn for adding that const string to
struct).

this commit change the structure and code to reflect this

some other revelead currently the abort shutdown does not work against my test machine even if it returns successfully ... need investigation
which we can use to link against Samba unit test programs. Now we can
compile and link unit tests without having to create 4MB executables
for each program
It's called libbigballofmud.so both to discourage casual usage and
also to reflect what the dependencies within Samba have become.
Also tidied up some of Richard's code (I don't think he uses the compiler
flags -g -Wall -Wshadow -Wstrict-prototypes -Wpointer-arith -Wcast-qual like
I do :-) :-).

changed cli_nt_setup_creds() to call cli_net_auth_2 or cli_net_auth_3 based on a switch.
pass also the negociation flags all the way.
all the places calling cli_nt_setup_creds() are still using cli_net_aut2(), it's just for future use and for rpcclient.
in the future we will be able to call auth_2 or auth_3 as we want.

send us. As it stands, we incorrectly set it to the number of bytes we are

something larger). Improves RPC client performance.
setups.
- split up the ads structure into logical pieces. This makes it much
easier to keep things like the authentication realm and the server
realm separate (they can be different).
- allow ads callers to specify that no sasl bind should be performed
(used by "net ads info" for example)
- fix an error with handing ADS_ERROR_SYSTEM() when errno is 0
- completely rewrote the code for finding the LDAP server. Now try DNS
methods first, and try all DNS servers returned from the SRV DNS
query, sorted by closeness to our interfaces (using the same sort code
as we use in replies from WINS servers). This allows us to cope with
ADS DCs that are down, and ensures we don't pick one that is on the
other side of the country unless absolutely necessary.
- recognise dnsRecords as binary when displaying them
- cope with the realm not being configured in smb.conf (work it out
from the LDAP server)
- look at the trustDirection when looking up trusted domains and don't
include trusts that trust our domains but we don't trust
theirs.
- use LDAP to query the alternate (netbios) name for a realm, and make
sure that both and long and short forms of the name are accepted by
winbindd. Use the short form by default for listing users/groups.
- rescan the list of trusted domains every 5 minutes in case new trust
relationships are added while winbindd is running
- include transient trust relationships (ie. C trusts B, B trusts A,
so C trusts A) in winbindd.
- don't do a gratuituous node status lookup when finding an ADS DC (we
don't need it and it could fail)
- remove unused sid_to_distinguished_name function
- make sure we find the allternate name of our primary domain when
operating with a netbiosless ADS DC (using LDAP to do the lookup)
- fixed the rpc trusted domain enumeration to support up to approx
2000 trusted domains (the old limit was 3)
- use the IP for the remote_machine (%m) macro when the client doesn't
supply us with a name via a netbios session request (eg. port 445)
- if the client uses SPNEGO then use the machine name from the SPNEGO
auth packet for remote_machine (%m) macro
- add new 'net ads workgroup' command to find the netbios workgroup
name for a realm
in the reverse).
* add in new printer change notify code from SAMBA_2_2
* add in se_map_standard() from 2.2 in _spoolss_open_printer_ex()
* sync up the _print_queue_struct in smb.h (why did someone change the
user/file names in fs_user/fs_file (or vice-versa) ? )
* sync up some cli_spoolss_XXX functions
- Move rpc_client/cli_trust.c to smbd/change_trust_pw.c
- It hasn't been used by anything else since smbpasswd lost its -j
- Add a TALLOC_CTX to the auth subsytem. These are only valid for the length
of the calls to the individual modules, if you want a longer context hide it
in your private data.
Similarly, all returns (like the server_info) should still be malloced.
- Move the 'ntdomain' module (security=domain in oldspeak) over to use the new
libsmb domain logon code. Also rework much of the code to use some better
helper functions for the connection - getting us much better error returns
(the new code is NTSTATUS).
The only remaining thing to do is to figure out if tpot's 0xdead 0xbeef for
the LUID feilds is sufficient, or if we should do random LUIDs as per the old
code.
Similarly, I'll move winbind over to this when I get a chance.
This leaves the SPOOLSS code and some cli_pipe code as the only stuff still in
rpc_client, at least as far as smbd is concerned.
While I've given this a basic rundown, any testing is as always appriciated.
Andrew Bartlett
This moves the rest of the functionality into the 'net rpc join' code.
Futhermore, this moves that entire area over to the libsmb codebase, rather
than the crufty old rpc_client stuff.
I have also fixed up the smbpasswd -a -m bug in the process.
We also have a new 'net rpc changetrustpw' that can be called from a
cron-job to regularly change the trust account password, for sites
that run winbind but not smbd.
With a little more work, we can kill rpc_client from smbd entirly!
(It is mostly the domain auth stuff - which I can rework - and the
spoolss stuff that sombody else will need to look over).
Andrew Bartlett
name_status_find() call here should look up a #1c name instead of #1d.
This fixes some bugs currently with BDC authentication in winbindd and in
smbd as you can't query the #1d name with the ip address of a BDC.
Who is Uncle Tom Cobbley anyway?
subystem.
The particular aim is to modularized the interface - so that we
can have arbitrary password back-ends.
This code adds one such back-end, a 'winbind' module to authenticate
against the winbind_auth_crap functionality. While fully-functional
this code is mainly useful as a demonstration, because we don't get
back the info3 as we would for direct ntdomain authentication.
This commit introduced the new 'auth methods' parameter, in the
spirit of the 'auth order' discussed on the lists. It is renamed
because not all the methods may be consulted, even if previous
methods fail - they may not have a suitable challenge for example.
Also, we have a 'local' authentication method, for old-style
'unix if plaintext, sam if encrypted' authentication and a
'guest' module to handle guest logins in a single place.
While this current design is not ideal, I feel that it does
provide a better infrastructure than the current design, and can
be built upon.
The following parameters have changed:
- use rhosts =
This has been replaced by the 'rhosts' authentication method,
and can be specified like 'auth methods = guest rhosts'
- hosts equiv =
This needs both this parameter and an 'auth methods' entry
to be effective. (auth methods = guest hostsequiv ....)
- plaintext to smbpasswd =
This is replaced by specifying 'sam' rather than 'local'
in the auth methods.
The security = parameter is unchanged, and now provides defaults
for the 'auth methods' parameter.
The available auth methods are:
guest
rhosts
hostsequiv
sam (passdb direct hash access)
unix (PAM, crypt() etc)
local (the combination of the above, based on encryption)
smbserver (old security=server)
ntdomain (old security=domain)
winbind (use winbind to cache DC connections)
Assistance in testing, or the production of new and interesting
authentication modules is always appreciated.

code.
In particular this assists tpot in some of his work, becouse it provides the
connection between the authenticaion and the vuid generation.
Major Changes:
- Fully malloc'ed structures.
- Massive rework of the code so that all structures are made and destroyed
using malloc and free, rather than hanging around on the stack.
- SAM_ACCOUNT unix uids and gids are now pointers to the same, to allow them
to be declared 'invalid' without the chance that people might get ROOT by
default.
- kill off some of the "DOMAIN\user" lookups. These can be readded at a more
appropriate place (probably domain_client_validate.c) in the future. They
don't belong in session setups.
- Massive introduction of DATA_BLOB structures, particularly for passwords.
- Use NTLMSSP flags to tell the backend what its getting, rather than magic
lenghths.
- Fix winbind back up again, but tpot is redoing this soon anyway.
- Abstract much of the work in srv_netlog_nt back into auth helper functions.
This is a LARGE change, and any assistance is testing it is appriciated.
Domain logons are still broken (as far as I can tell) but other functionality
seems
intact.
Needs testing with a wide variety of MS clients.
Andrew Bartlett
and also completes the switch to lang_tdb.c. SWAT should now work
with a po file in the lib/ directory
also removed useless SYSLOG defines in many files
they can have general effect.
Fixed up workstaion support in the rest of samba, so that we can do these
checks.
Pass through the workstation for cli_net_logon(), if supplied.
In particuar, it moves the domain_client_validate stuff out of
auth_domain.c to somwhere where they (I hope) they can be shared
with winbind better. (This may need some work)
The main purpose of this patch was however to improve some of the
internal documentation and to correctly place become_root()/unbecome_root()
calls within the code.
Finally this patch moves some more of auth.c into other files, auth_unix.c
in this case.
Andrew Bartlett
samba-technical a few weeks ago.
The idea here is to standardize the checking of user names and passwords,
thereby ensuring that all authtentications pass the same standards. The
interface currently implemented in as
nt_status = check_password(user_info, server_info)
where user_info contains (mostly) the authentication data, and server_info
contains things like the user-id they got, and their resolved user name.
The current ugliness with the way the structures are created will be killed
the next revision, when they will be created and malloced by creator functions.
This patch also includes the first implementation of NTLMv2 in HEAD, but which
needs some more testing. We also add a hack to allow plaintext passwords to be
compared with smbpasswd, not the system password database.
Finally, this patch probably reintroduces the PAM accounts bug we had in
2.2.0, I'll fix that once this hits the tree. (I've just finished testing
it on a wide variety of platforms, so I want to get this patch in).
changeover. For my own sainity I have created a new function to fill out both
the header and buffer for a string in an RPC struct. This DOES NOT take a
length argument, only the actual string to be placed.
The RPC code is currently littered with code that does init_uni_hdr() followed
immidiatly by init_unistr2(), and often the length argument is wrong. (It was
for the code I changed, even before the charset stuff). Another bug where we
made strings AT LEAST MAX_UNICODE_LEN long hid this bug.
This works for loopback connections to Samba, and can't be any more broke than
it was before :-). (We had double and revese conversions, fun...).
In particular this makes us multibyte complient.
In any case, if there are no objections I will slowly convert other bits of
code to the same system.
This commit gets rid of all our old codepage handling and replaces it with
iconv. All internal strings in Samba are now in "unix" charset, which may
be multi-byte. See internals.doc and my posting to samba-technical for
a more complete explanation.
for and ignore ERRmoredata errors as the client library doesn't support
32-bit error messages.
Added some annotations for the RPC pipe code to make it a bit clearer
maybe.
on different pipes. This seriously confuses NT. Unfortunately HEAD
branch is limited to one rpc pipe per connection as the fnum is stored
inside the cli_state structure. It should really be broken out into
it's own structure so multiple pipes can be opened on one TCP/IP socket.
What a good idea! But look over here! I've already done it in another
workarea but it will require a day or two to refactor some of the internal
samba rpc client stuff (i.e netlogon requests) so it will remain uncommitted
for another while.
We were reading the endainness in the RPC header and then never propagating
it to the internal parse_structs used to parse the data.
Also removed the "align" argument to prs_init as it was *always* set to
4, and if needed can be set differently on a case by case basis.
Now ready for AS/U testing when Herb gets it set up :-).
Jeremy.
Probably Veritas too... :-).
It allows Samba as a domain member to authenticate against an AS/U server such
as the older HP PDC product or PD Netlink. It does this by trying a netlogon
with info level 3 and then falling back to info level 2 if the PDC returns
invalid info level.
Jeremy.

that for the first hour after the password change is searches for the
PDC using the 1B name not the 1C name as domain replication may not
have occured.

in the RPC code. This change was prompted by trying to save a long (>256)
character comment in the printer properties page.
The new system associates a TALLOC_CTX with the pipe struct, and frees
the pool on return of a complete PDU.
A global TALLOC_CTX is used for the odd buffer allocated in the BUFFERxx
code, and is freed in the main loop.
This code works with insure, and seems to be free of memory leaks and
crashes (so far) but there are probably the occasional problem with
code that uses UNISTRxx structs on the stack and expects them to contain
storage without doing a init_unistrXX().
This means that rpcclient will probably be horribly broken.
A TALLOC_CTX also needed associating with the struct cli_state also,
to make the prs_xx code there work.
The main interface change is the addition of a TALLOC_CTX to the
prs_init calls - used for dynamic allocation in the prs_XXX calls.
Now this is in place it should make dynamic allocation of all RPC
memory on unmarshall *much* easier to fix.
Jeremy.
So fixed enumprinterdatas in rpcclient to debug the server code,
and found that the parsing code was missing 2 prs_align().
We are not crashing NT anymore. :-)

head/tng merge.
It goes something like this:
- headers from tng get copied over one at a time
- the old headers get renamed to *_old.h
- server side code that used the old headers gets a
#define OLD_NTDOMAIN 1
#undef OLD_NTDOMAIN
at the start and end of the code
- mkproto.awk recognises these special defines and does magic stuff so
that each .c file sees the right headers
- we start moving the rpc client libraries from tng to head.
if this goes OK then, in theory, we should be able to move the client
side rpc code from tng to head without disturbing the existing head
server side code. Then when that works we can consider merging the
server side.
it remains to be seen if this scheme will work. So far I've moved
rpc_samr.h and don't seem to have broken anything.
Note this this is still a very delicate operation, as at every step of
the way I want to keep head fully functional. Please don't take part
unless you discuss it with me first.
include/byteorder.h: Added alignment macros.
include/nameserv.h: Added defines for msg_type field options - from rfc1002.

This fixes our netbios scope handling. We now have a 'netbios scope' option
in smb.conf and the scope option is removed from make_nmb_name()
this was prompted by a bug in our PDC finding code where it didn't append
the scope to the query of the '*' name.
instead of either sysv or mmap shared memory or lock files.
this means we can now completely remove
locking_shm.c
locking_slow.c
shmem.c
shmem_sysv.c
and lots of other things also got simpler
locking.c got a bit larger, but is much better compartmentalised now
done a minimal amout of clean-up in the Makefile, removing unnecessary
modules from the link stage. this is not complete, yet, and will
involve some changes, for example to smbd, to remove dependencies on
the password database API that shouldn't be there. for example,
smbd should not ever call getsmbpwXXX() it should call the Samr or Lsa
API.
this first implementation has minor problems with not reinstantiating
the same services as the caller. the "homes" service is a good example.
pdus, and then feeds them over either a "local" function call or a "remote"
function call to an msrpc service. the "remote" msrpc daemon, on the
other side of a unix socket, then calls the same "local" function that
smbd would, if the msrpc service were being run from inside smbd.
this allows a transition from local msrpc services (inside the same smbd
process) to remote (over a unix socket).
removed reference to pipes_struct in msrpc services. all msrpc processing
functions take rpcsrv_struct which is a structure containing state info
for the msrpc functions to decode and create pdus.
created become_vuser() which does everything not related to connection_struct
that become_user() does.
removed, as best i could, connection_struct dependencies from the nt spoolss
printing code.
todo: remove dcinfo from rpcsrv_struct because this stores NETLOGON-specific
info on a per-connection basis, and if the connection dies then so does
the info, and that's a fairly serious problem.
had to put pretty much everything that is in user_struct into parse_creds.c
to feed unix user info over to the msrpc daemons. why? because it's
expensive to do unix password/group database lookups, and it's definitely
expensive to do nt user profile lookups, not to mention pretty difficult
and if you did either of these it would introduce a complication /
unnecessary interdependency. so, send uid/gid/num_groups/gid_t* +
SID+num_rids+domain_group_rids* + unix username + nt username + nt domain
+ user session key etc. this is the MINIMUM info identified so far that's
actually implemented. missing bits include the called and calling
netbios names etc. (basically, anything that can be loaded into
standard_sub() and standard_sub_basic()...)
time out of sending the session setup on Solaris 2.6. No idea.
I'll work on it some tomorrow. This is to fix the "Unable to
setup password vectors" thingy.
Also changed an inet_aton() to inet_addr() as the former is
not very portable :-)
Luke, I set the redir flag to false because the connection to
the smb-agent was failing and smbpasswd bombed. Double check me
on this one.

damn, this one is bad.
started, at least two days ago, to add an authentication mechanism to
the smbd<->msrpc redirector/relay, such that sufficient unix / nt
information could be transferred across the unix socket to do a
become_user() on the other side of the socket.
it is necessary that the msrpc daemon inherit the same unix and nt
credentials as the smbd process from which it was spawned, until
such time as the msrpc daemon receives an authentication request
of its own, whereupon the msrpc daemon is responsible for authenticating
the new credentials and doing yet another become_user() etc sequence.
created an "nmb-agent" utility that, yes: it connects to the 137 socket
and accepts unix socket connections which it redirects onto port 137.
it uses the name_trn_id field to filter requests to the correct
location.
name_query() and name_status() are the first victims to use this
feature (by specifying a file descriptor of -1).
moved smb-agent over to a single-process model instead of fork()
in order to reuse client connections. except, of course, you
can't do a select() on the same socket connections! argh!
ideas from ssh-agent.
the intent is to be able to share smb sessions using cli_net_use_add()
across multiple processes, where one process knows the target server
name, user name and domain, but not the smb password.
lp_trusted_domains() parameter, so trusted domain logins should work,
right, if you put user = TRUSTED_DOMAIN\NTuser in "domain name map", right?
right - as _long_ as you're not using NTLMv2, because the damn NT username
gets mapped to the damn unix name too early, and NTLMv2 challenge-responses
are based on the client's user name, client's domain name, client's host name
etc damn etc.
so it becomes necessary to stop using char* username because this allows
for massive amounts of confusion as to which username is being referred to.
the underlying unix username on the local unix system that is associated with
the smbd process that represents the NT username? or the NT username itself?
they should all be replaced with cli_establish_connection().
created cli_use_wait_keyboard() which waits on multiple cli_states
and swallows session keepalives.
from previous lsaquery command. over-ridden from DOMAIN\username
2) initialisation of cli_state is a little more specific: sets use_ntlmv2
to Auto. this can always be over-ridden.
3) fixed reusage of ntlmssp_cli_flgs which was being a pain
4) added pwd_compare() function then fixed bug in cli_use where NULL
domain name was making connections multiply unfruitfully
5) type-casting of mallocs and Reallocs that cause ansi-c compilers to bitch
by cli_net_use_add() and cli_net_use_del(). MSRPC connections are
established with cli_connection_init(), and automatically unlinked with
cli_connection_unlink. client states are _reused_ by cli_connection_init.
if microsoft bothered to publish it. actually, there are good reasons
for not publishing it: people might write programs for it, and then
those programs wouldn't work on nt5, for example...
verified that lsaquery, lsalookupsids work, and found some bugs in the

the only significant coding difference is the introduction of a

this makes the msrpc functions look more and more like their nt equivalents.
who-hou!
have we got. and what data do we have. hmm.. i wonder what the NTLMv2
user session key can be... hmmm... weell.... there's some hidden data
here, generated from the user password that doesn't go over-the-wire,
so that's _got_ to be involved. and... that bit of data took a lot of
computation to produce, so it's probably _also_ involved... and md4 no, md5?
no, how about hmac_md5 yes let's try that one (the other's didn't work)
oh goodie, it worked!
i love it when this sort of thing happens. took all of fifteen minutes to
guess it. tried concatenating client and server challenges. tried
concatenating _random_ bits of client and server challenges. tried
md5 of the above. tried hmac_md5 of the above. eventually, it boils down
to this:
kr = MD4(NT#,username,domainname)

reg_io_r_info() working properly. previously they weren't well
understood (well, they were the first of the registry functions i did,
back in december 97, ok??? :-)
set ntversion to 0x1 in SAMQUERY, so that we reply same as NT4 srv.
for which a PDC is responsible. typical answers are:
<Name of Domain> plus <Builtin>.
against a hierarchical, down-level-compatible NT5 PDC, there's likely to
be more than these two entries!!!!!
works with command-line completion on the service name (ohh yesss, this
is becoming my favourite bit of functionality-on-the-side hee hee :)
had to fix the svc_io_q_start_service() code which was missing the
ptr_argv[] array in between the array-size and the UNISTR2-array.
i.e it's actually an array of _pointers_ to unicode strings...
implementation (NT5) when you discover that your code is trash.
samr_enum_dom_users(), samr_enum_dom_aliases() and samr_enum_dom_groups()
all take a HANDLE for multiple-call enumeration purposes.
samr_lookup_rids() moved to a dynamic memory structure not a
static one limited to 32 RIDs. cli_pipe.c reading wasn't checking
ERRmoredata when DOS error codes negotiated (this terminates
MSRPC code with prejudice).
this format is what i would like _all_ these functions to be
(returning status codes, not BOOL) but that's a horrendous
amount of work at the moment :)
a problem i was having.
- added rudimentary CAP_STATUS32 support for same reason.
- added hard-coded, copy-the-same-data-from-over-the-wire version of
CAP_EXTENDED_SECURITY, which is a security-blob to encapsulate
GSSAPI which encodes
SPNEGO which is used to negotiate
Kerberos or NTLMSSP. i have implemented
NTLMSSP which negotiates
NTLMv1 or NTLMv2 and 40-bit or 128-bit etc. i have implemented
NTLMv1 / 40-bit.
*whew*.
simplest method to get rpcclient's reggetsec command working. the
buffers passed as arguments in do_reg_get_key_sec() do need to be
locally allocated not dynamically allocated, as two calls to
reg_get_key_sec() are needed. on the first, the server fills in the
size of the security descriptor buffer needed. on the second, the
server fills in the security descriptor buffer.
Added synchronise_passdb function to update accounts in a BDC's smbpasswd.
Improved rpc_read, which was still somewhat broken for multiple PDU's.
modify_trust_password must initialise cli.pwd (pwd_set_nullpwd).
* Added SEC_CHAN_BDC
* Propagate sec_chan into the various functions which change trust account
passwords, so they can be used for domain control and inter-domain
trusts.
* Fix for endianness problem reported by Edan Idzerda <edan@mtu.edu>. A
BUFFER2 is really a "unibuf" in my terminology and we should treat it as
such.
* Added some more common NT structures (BIGINT, BUFHDR2, BUFFER4).
* Added NET_SAM_SYNC (-> NetDatabaseSync2) RPC for account replication.
Still experimental and incomplete, with a few too many NULL security
descriptors lying around (must go look at Jeremy's SD code). Haven't
worked out password encryption yet either.
However, the XXX_INFO structures I've added to rpc_netlogon.h are quite
nice as they give some insight into how these objects are stored in the
SAM.
(-> LsarQuerySecret) on client side, including rpcclient command
"querysecret" for others to play with.
The major obstacle is working out the encryption algorithm used
for the secret value. It definitely uses the NT hash as part of the
key, and it seems the block size is 64 bits - probably DES based -
but I can't work out what's done in between. Help required.
* Added SAMR_LOOKUP_DOMAIN (-> SamrLookupDomainInSamServer)
* Added real SAMR_ENUM_DOM_GROUPS (corresponding to
SamrEnumerateGroupsInDomain). The existing one is just an alias for
SamrQueryDisplayInformation (see below).
* Added three extra info levels to SAMR_QUERY_DISPINFO. Info level 3 is
what was previously SAMR_ENUM_DOM_GROUPS; info levels 4 and 5 are
simple user/group list requests used by Win9x and I suspect (haven't
checked) the "low speed connection" User Manager.
* Added another two aliases for SAMR_QUERY_DISPINFO, opcodes 0x30 and
0x33. Usually the first is with info level 3 and the second 4 but there is
some overlap so indeed these should be implemented as just aliases.
* Return ERRDOS/ERRmoredata on extra data instead of
STATUS_BUFFER_OVERFLOW for Win95's benefit. On a named pipe this results
in an SMBreadX as usual.
Still need to fix SAMR_QUERY_DOMAIN_INFO which has a hard-coded number of
users and groups - which Win95 proceeds to truncate at.
No more ugly static library buffers and all functions take a destination
string length (especially unistrcpy was rather dangerous; we were only
saved by the fact that datagrams are limited in size).
also needed to use start index properly and generate next index.
both client and server code need to recognise error code 0x105
when there's not enough room to store all the users in one call.
sort this out another time.
LsaLookupSids etc from within SamrQueryAliasMembers, for example.
fnum is now a parameter to client functions. thanks to mike black
for starting the ball rolling.
attempt at taking lib/uid.c and getting a unix security context
change module that is independent of "cnums" and "snums".
a security context is needed for pipes, not just IPC$ or other
services.
- group database API
added add_group/alias_member, del_group/alias_member,
del_group/alias_entry functions. del_builtin_entry() is
deliberately set to NULL to cause an exception, you cannot
delete builtin aliases.
- parse_lsa.c srv_lsa.c
fixed lookup_names code, it was a load of trash and didn't do
anything.
- cmd_samr.c rpcclient.c srv_samr.c
added "deletegroup", "deletealias", "delaliasmem", "delgroupmem",
"addgroupmem", "addaliasmem", "createalias", "creategroup", to
both client and server code.
server code calls into unix stubs right now, which don't actually
do anything. the only instance where they are expected to do
anything is in appliance mode NOT even in the ldap code or anything.
client code modified to call samr_lookup_names() for group code
(because we can) and lsa_lookup_names() for alias code (because
we have to).
- srv_lookup.c
oops, lookup on unsplit name, we got lookup on DOMAIN, DOMAIN\name
instead of DOMAIN, name.
