Currently the only backend which works is smbpasswd (tdb, LDAP, and NIS+)
are broken, but they were somewhat broken before. :)
The following functions implement the storage manipulation interface
/*The following definitions come from passdb/pdb_smbpasswd.c */
BOOL pdb_setsampwent (BOOL update);
void pdb_endsampwent (void);
SAM_ACCOUNT* pdb_getsampwent (void);
SAM_ACCOUNT* pdb_getsampwnam (char *username);
SAM_ACCOUNT* pdb_getsampwuid (uid_t uid);
SAM_ACCOUNT* pdb_getsampwrid (uint32 rid);
BOOL pdb_add_sam_account (SAM_ACCOUNT *sampass);
BOOL pdb_update_sam_account (SAM_ACCOUNT *sampass, BOOL override);
BOOL pdb_delete_sam_account (char* username);
There is also a host of pdb_set..() and pdb_get..() functions for
manipulating SAM_ACCOUNT struct members. Note that the struct
passdb_ops {} has gone away. Also notice that struct smb_passwd
(formally in smb.h) has been moved to passdb/pdb_smbpasswd.c
and is not accessed outisde of static internal functions in this
file. All local password searches should make use of the the SAM_ACCOUNT
struct and the previously mentioned functions.
I'll write some documentation for this later. The next step is to fix
the TDB passdb backend, then work on spliting the backends out into
share libraries, and finally get the LDAP backend going.
What works and may not:
o domain logons from Win9x works
o domain logons from WinNT 4 works
o user and group enumeration
as implemented by Tim works
o file and print access works
o changing password from
Win9x & NT ummm...i'll fix this tonight :)
If I broke anything else, just yell and I'll fix it. I think it
should be fairly quite.

cleanup of create_user
cleanup of rid/sid mix in samr. now we only have sid.
some prs_align() missing in parse_samr.c
a small debug change in srv_pipe.c
You still can't change a user's password in this commit.
Will be availble in the next one.

Added a become_root()/unbecome_root() (push/pop security context)
around the initgroups() call to ensure it would succeed. Hmmm - I
wonder if this call being done as non-root might explain any "group access"
bugs we've had in the past....

obscure way.

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.

structure so authenticated pipe users can have their unix groups set when
become_authenticated_pipe_user() is called.
(This used to be commit 55c9bf124dc661df43bfe582ef14b1297aeaf0fa)
through to the individual pipe api calls. Instead of passing two
prs_struct pointers, we now pass the pipes_struct pointer which contains
the former information as well as other useful stuff like the vuid.

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.

can now do a :

size of SMBtrans response, timeout of 10 seconds. read_data() _certainly_
doesn't work, as you don't know what size of the data is going to come
back that needs to be fed back in the SMBtrans response. yes, oops :-)

part of the data stream. read_data() is a wrapper to guarantee
receiving exactly the requested number of bytes.
(This used to be commit 90c27b7bffa9b2121eaed0e07931830c3ba308d7)
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.
(This used to be commit caa50525220b0d0250fa139367593c2de2c12135)
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()...)
(This used to be commit aa3c659a8dba0437c17c60055a6ed30fdfecdb6d)
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.
(This used to be commit 30c7fdd6ef10ecd35594311c1b250b95ff895489)
one horrible cut / paste job from smbd, plus a code split of shared
components between the two.
the job is not _yet_ complete, as i need to be able to do a become_user()
call for security reasons. i picked lsarpcd first because you don't
_need_ security on it (microsoft botched so badly on this one, it's not
real. at least they fixed this in nt5 with restrictanonymous=0x2).
fixing this involves sending the current smb and unix credentials down
the unix pipe so that the daemon it eventually goes to can pick them
up at the other end.
i can't believe this all worked!!!

desired flag MUST be set in any NBT UDP packets sent to a WINS
server, else they will go to the WINS client side of the NT NetBIOS
kernel instead, and will get trashed.

- disabled (AGAIN) the GETDC "if (MAILSLOT\NTLOGON)" code that will get
NT5rc2 to work but WILL break win95 (AGAIN). this needs _not_ to be
re-enabled but to be replaced with a better mechanism.
- added SMBwrite support (note: SMBwriteX already existed) as NT5rc2 is
sending DCE/RPC over SMBwrite not SMBwriteX.

- removed SAMR_UNKNOWN_32
- added SAMR_SET_USERINFO (opcode 0x32)
- added level 0x1 to SAMR_QUERY_DOM_INFO (needed for create user)
- fixed pwdb_gethexpwd() it was failing on XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
- added mod_sam21pwd_entry()
- preparing to call mod_sam21pwd_entry()

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).
