Jerry, I tried to adopt to prs_pointer() where possible and to not
interfere with your work for usrmgr.
- Add "net rpc trustdom vampire"-tool.
This allows to retrieve Interdomain Trust(ed)-Relationships from
NT4-Servers including cleartext-passwords (still stored in the local
secrets.tdb).
The net-hook was done in cooperation with Lars Mueller
<lmuelle@suse.de>.
To vampire trusted domains simply call:
net rpc trustdom vampire -S nt4dc -Uadmin%pass

pulling back all recent rpc changes from trunk into
3.0. I've tested a compile and so don't think I've missed
any files. But if so, just mail me and I'll clean backup
in a couple of hours.
Changes include \winreg, \eventlog, \svcctl, and
general parse_misc.c updates.
I am planning on bracketing the event code with an
#ifdef ENABLE_EVENTLOG until I finish merging Marcin's
changes (very soon).
* define some const SE_PRIV structure for use when
you need a SE_PRIV* to a privilege
* fix an annoying compiler warngin in smbfilter.c
* translate SIDs to names in 'net rpc rights list accounts'
* fix a seg fault in cli_lsa_enum_account_rights caused by
me forgetting the precedence of * vs. []
(based on Simo's code in trunk). Rewritten with the
following changes:
* privilege set is based on a 32-bit mask instead of strings
(plans are to extend this to a 64 or 128-bit mask before
the next 3.0.11preX release).
* Remove the privilege code from the passdb API
(replication to come later)
* Only support the minimum amount of privileges that make
sense.
* Rewrite the domain join checks to use the SeMachineAccountPrivilege
instead of the 'is a member of "Domain Admins"?' check that started
all this.
Still todo:
* Utilize the SePrintOperatorPrivilege in addition to the 'printer admin'
parameter
* Utilize the SeAddUserPrivilege for adding users and groups
* Fix some of the hard coded _lsa_*() calls
* Start work on enough of SAM replication to get privileges from one
Samba DC to another.
* Come up with some management tool for manipultaing privileges
instead of user manager since it is buggy when run on a 2k client
(haven't tried xp). Works ok on NT4.
supported pipe. Netlogon is still special, as we open that twice, one to do
the auth2, the other one with schannel.
The client interface is completely unchanged for those who only use a single
pie. cli->pipe_idx is used as the index for everything except the "real"
client rpc calls, which have been explicitly converted in my last commit. Next
step is to get winbind to just use a single smb connection for multiple pipes.
Volker
patches.
Pass down the pipe_idx down to all functions in cli_pipe where nt_pipe_fnum is
referenced. First step towards having multiple pipes on a cli_struct. The idea
is to not have a single nt_pipe_fnum but an array for the pipes we support.
Volker
The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting
acct_flags with bizarre values, breaking a lot of things.
This patch is successfully running in a production environment for quite
some time now and is required to finally allow Exchange 5.5 to access
another Exchange Server when both are running on NT4 in a
samba-controlled domain. This also allows Exchange Replication to take
place, Exchange Administrator to access other Servers in the network,
etc. Fixes Bugzilla #1136.
Thanks abartlet for helping me with that one.

* add IA64 to the architecture table of printer-drivers
* add new "net"-subcommands:
net rpc printer migrate {drivers|printers|forms|security|settings|all}
[printer]
net rpc share migrate {shares|files|all} [share]
this is the first part of the migration suite. this will will (once
feature-complete) allow to do 1:1 server-cloning in the best possible way by
making heavy use of samba's rpc_client-functions. all migration-steps
are implemented as rpc/smb-client-calls; net communicates via rpc/smb
with two servers at the same time (a remote, source server and a
destination server that currently defaults to the local smbd). this
allows e. g. printer-driver migration including driverfiles, recursive
mirroring of file-shares including file-acls, etc. almost any migration
step can be called with a migrate-subcommand to provide more flexibility
during a migration process (at the cost of quite some redundancy :) ).
"net rpc printer migrate settings" is still in a bad condition (many
open questions that hopefully can be adressed soon).
"net rpc share migrate security" as an isolated call to just migrate
share-ACLs will be added later.
Before playing with it, make sure to use a test-server. Migration is a
serious business and this tool-set can perfectly overwrite your
existing file/print-shares.
* along with the migration functions had to make I the following
changes:
- implement setprinter level 3 client-side
- implement net_add_share level 502 client-side
- allow security descriptor to be set in setprinterdata level 2

On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork().
For other systems, we now only re-seed after a fork, and on startup.
No need to do it per-operation. This removes the 'need_reseed'
parameter from generate_random_buffer().
Andrew Bartlett
for setting up an schannel connection. This solves the problem
of a Samba DC running winbind, trusting a native mode AD domain,
and needing to enumerate AD users via wbinfo -u.
group_info4 in set_dom_group_info also has the level in the record
itself. This seems not to be an align. Tested with NT4 usrmgr.exe. It can
still create a domain group on a samba machine.
Volker
As well as avoiding DOS charset issues, this scheme returns useful error
codes, that we can map back via the pam interface.
This patch also cleans up the interfaces used for password buffers, to
avoid duplication of code.
Andrew Bartlett
domains, this patch ensures that we always use the ADS backend when
security=ADS, and the remote server is capable.
The routines used for this behaviour have been upgraded to modern Samba
codeing standards.
This is a change in behaviour for mixed mode domains, and if the trusted
domain cannot be reached with our current krb5.conf file, we will show
that domain as disconnected.
This is in line with existing behaviour for native mode domains, and for
our primary domain.
As a consequence of testing this patch, I found that our kerberos error
handling was well below par - we would often throw away useful error
values. These changes move more routines to ADS_STATUS to return
kerberos errors.
Also found when valgrinding the setup, fix a few memory leaks.
While sniffing the resultant connections, I noticed we would query our
list of trusted domains twice - so I have reworked some of the code to
avoid that.

defaults specified by the caller to prevail.
Don't use NTLM2 for RPC pipes, until we know how it works in signing or sealing.
Call ntlmssp_sign_init() unconditionally in the client - we setup the
session key, why not setup the rest of the data.
Andrew Bartlett
This means that we now support 'net rpc join' with KRB5 (des based)
logins. Now, you need to hack 'net' to do that, but the principal is
important...
When we add kerberos to 'net rpc', it should be possible to still do
user management and the like over RPC.
(server-side support to follow shortly)
Andrew Bartlett
- NTLM2 support in the server
- KEY_EXCH support in the server
- variable length session keys.
In detail:
- NTLM2 is an extension of NTLMv1, that is compatible with existing
domain controllers (unlike NTLMv2, which requires a DC upgrade).
* This is known as 'NTLMv2 session security' *
(This is not yet implemented on the RPC pipes however, so there may
well still be issues for PDC setups, particuarly around password
changes. We do not fully understand the sign/seal implications of
NTLM2 on RPC pipes.)
This requires modifications to our authentication subsystem, as we
must handle the 'challege' input into the challenge-response algorithm
being changed. This also needs to be turned off for
'security=server', which does not support this.
- KEY_EXCH is another 'security' mechanism, whereby the session key
actually used by the server is sent by the client, rather than being
the shared-secret directly or indirectly.
- As both these methods change the session key, the auth subsystem
needed to be changed, to 'override' session keys provided by the
backend.
- There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation.
- The 'names blob' in NTLMSSP is always in unicode - never in ascii.
Don't make an ascii version ever.
- The other big change is to allow variable length session keys. We
have always assumed that session keys are 16 bytes long - and padded
to this length if shorter. However, Kerberos session keys are 8 bytes
long, when the krb5 login uses DES.
* This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. *
- Add better DEBUG() messages to ntlm_auth, warning administrators of
misconfigurations that prevent access to the privileged pipe. This
should help reduce some of the 'it just doesn't work' issues.
- Fix data_blob_talloc() to behave the same way data_blob() does when
passed a NULL data pointer. (just allocate)
REMEMBER to make clean after this commit - I have changed plenty of data structures...
the bind response to WKSSVC it does not send \PIPE\ntsvcs as NT4 (did not
check w2k) but \PIPE\wkssvc. I'm not sure whether we should make this check at
all, so making it a bit more liberal should hopefully not really hurt.
Volker
In cli_lsa_lookup_sids don't leave the domain field uninitialized if
some sid could not be mapped. Otherwise this call is unnecessarily
complicated to call.
Volker
(no need to include all of smbd files to use some basic sec functions)
also minor compile fixes
couldn't compile to test these due to some kerberos problems wirh 3.0,
but on HEAD they're working well, so I suppose it's ok to commit
>Fix for #480. Change the interface for init_unistr2 to not take a length

>Jeremy.
- When connecting to the NETOGON pipe, we make a call to auth2, in order
to verify our identity. This call was being made with negotiation flags
of 0x1ff. This caused our account to be downgraded. If we instead make
the call with flags > 1ff (such as 0x701ff), then this does not occour.
- This is *not* related to the use of kerberos for the CIFS-level connection
My theory is that Win2k has a test to see if we are sending *exactly* what
NT4 sent - setting any other flags seems to cause us to remain intact.
Also ensure that we only have 'setup schannel' code in a few places, not
scattered around cmd_netlogon too.
Andrew Bartlett
NTLMSSP with "" username, NULL password), and add --machine-pass (-P) to
all of Samba's clients.
When connecting to an Active Directory DC, you must initiate the CIFS level
session setup with Kerberos, not a guest login. If you don't, your machine
account is demoted to NT4.
Andrew Bartlett
* use DsEnumerateDomainTrusts() instead of LDAP search.
wbinfo -m now lists all trusted downlevel domains and
all domains in the forest.
Thnigs to do:
o Look at Krb5 connection trusted domains
o make sure to initial the trusted domain cache as soon
as possible
connection that set it up has been shut down.
(Also, pipes still connected, and reconnections to the same pipe (eg SAMR)
may continue to use that session key until their TCP/IP connection is shut
down)
Allow further testing by printing out the session key, and allowing it's input
into rpcclient.
Next step is automatic storage in a TDB.
Andrew Bartlett
the schannel code, but I've included that anyway. :-)
This patch revives the client-side NTLMSSP support for RPC named pipes
in Samba, and cleans up the client and server schannel code. The use of the
new code is enabled by the 'sign', 'seal' and 'schannel' commands in
rpcclient.
The aim was to prove that our separate NTLMSSP client library actually
implements NTLMSSP signing and sealing as per Microsoft's NTLMv1 implementation,
in the hope that knowing this will assist us in correctly implementing
NTLMSSP signing for SMB packets. (Still not yet functional)
This patch replaces the NTLMSSP implementation in rpc_client/cli_pipe.c with
calls to libsmb/ntlmssp.c. In the process, we have gained the ability to
use the more secure NT password, and the ability to sign-only, instead of
having to seal the pipe connection. (Previously we were limited to sealing,
and could only use the LM-password derived key).
Our new client-side NTLMSSP code also needed alteration to cope with our
comparatively simple server-side implementation. A future step is to replace
it with calls to the same NTLMSSP library.
Also included in this patch is the schannel 'sign only' patch I submitted to
the team earlier. While not enabled (and not functional, at this stage) the
work in this patch makes the code paths *much* easier to follow. I have also
included similar hooks in rpccleint to allow the use of schannel on *any* pipe.
rpcclient now defaults to not using schannel (or any other extra per-pipe
authenticiation) for any connection. The 'schannel' command enables schannel
for all pipes until disabled.
This code is also much more secure than the previous code, as changes to our
cli_pipe routines ensure that the authentication footer cannot be removed
by an attacker, and more error states are correctly handled.
(The same needs to be done to our server)
Andrew Bartlett
channel:
- If the domain name passed to create_rpc_bind_req() is empty, use
lp_workgroup()
- Correctly set the auth_padding field when the send_size is a multiple
of 8 bytes
I've tested with nt4sp6 and win2ksp0 and it seems to work, although
there are no password hashes transferred from win2k. The empty
passwords are being protected by the secure channel encryption though.
useful in the auth verifier yet. So this patch ignores it.
Really checking this would be a lot more intrusive: in rpc_api_pipe we
would have to distinguish between binds and normal requests, or have
more state in the netsec info of cli_state, which is also somewhat
hackish.
Volker
important once we start doing schannel, as there would be a lot more
roundtrips for the second PIPE open and bind. With this patch logging
in to a member server is a matter of two (three if you count the
ack...) packets between us and the DC.

- return NT_STATUS_NO_MEMORY instead of NT_STATUS_UNSUCESSFUL if a
talloc fails
- don't try and tallocate memory when the number of entries returned was
zero
- rename some cut&pasted variable names in enum domain aliases function
- return NT_STATUS_NO_MEMORY instead of NT_STATUS_UNSUCESSFUL if a
talloc fails
- don't try and tallocate memory when the number of entries returned was
zero
- rename some cut&pasted variable names in enum domain aliases function
This allows us to join as a BDC, without appearing on the network as one
until we have the database replicated, and the admin changes the configuration.
This also change the SID retreval order from secrets.tdb, so we no longer
require a 'net rpc getsid' - the sid fetch during the domain join is sufficient.
Also minor fixes to 'net'.
Andrew Bartlett
workstation, we have to use the workstation type, if we have a BDC account,
we must use the BDC type - even if we are pretending to be a workstation
at the moment.
Also actually store and retreive the last change time, so we can do
periodic password changes again (for RPC at least).
And finally, a couple of minor fixes to 'net'.
Andrew Bartlett
requests and responses and is only compiled in when --enable-developer
is passed to configure. It includes server and client side code for
generating and responding to functions on this pipe. The functions are:
- AddOne: add one to the uint32 argument and return ig
- EchoData: echo back a variable sized char array to the caller
- SourceData: request a variable sized char array
- SinkData: send a variable sized char array and throw it away
There's a win32 implementation of the client and server in the
junkcode CVS repository in the rpcecho-win32 subdirectory.
NTLM Authentication:
- Add a 'privileged' mode to Winbindd. This is achieved by means of a directory
under lockdir, that the admin can change the group access for.
- This mode is now required to access with 'CRAP' authentication feature.
- This *will* break the current SQUID helper, so I've fixed up our ntlm_auth
replacement:
- Update our NTLMSSP code to cope with 'datagram' mode, where we don't get a
challenge.
- Use this to make our ntlm_auth utility suitable for use in current Squid 2.5
servers.
- Tested - works for Win2k clients, but not Win9X at present. NTLMSSP updates
are needed.
- Now uses fgets(), not x_fgets() to cope with Squid environment (I think
somthing to do with non-blocking stdin).
- Add much more robust connection code to wb_common.c - it will not connect to
a server of a different protocol version, and it will automatically try and
reconnect to the 'privileged' pipe if possible.
- This could help with 'privileged' idmap operations etc in future.
- Add a generic HEX encode routine to util_str.c,
- fix a small line of dodgy C in StrnCpy_fn()
- Correctly pull our 'session key' out of the info3 from th the DC. This is
used in both the auth code, and in for export over the winbind pipe to
ntlm_auth.
- Given the user's challenge/response and access to the privileged pipe,
allow external access to the 'session key'. To be used for MSCHAPv2
integration.

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).
Andrew Bartlett
this commit change the structure and code to reflect this
some test revelead I'm right.
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 :-) :-).
