2003-02-17This patch fixes one of my longest-standing pet hates with Samba :-).Andrew Bartlett1-9/+9
When we look see if a user is in a list, and we try to 'expand' an @group, we should lookup the user's own list of groups, rather than looking for all the members of a group. I'm sure this will fix some nasty performance issues, particularly on large domains etc. In particular, this avoids contacting winbind at all, if the group is not a winbind group. (This caused a deadlock on my winbind-on-PDC setup). The groups list always includes the user's primary group, as per the getgrouplist manpage, and my recent changes to our implementation.

2003-02-10Some cleanups:Andrew Bartlett1-10/+31
- Don't use pstrcpy into an allocated string - use safe_strcpy() directly instead. - Keep a copy of the 'server_info' attached to the vuid. In future use this for things like the session key, homedir and full name instead of current copies. - Try to avoid memory leak/segfault on Realloc failure - clear up #endif comments Andrew Bartlett (This used to be commit 162477bb086827950b6cb71afa9bef62c2753c2e)

2002-10-12Nice *big* patch from metze.Andrew Bartlett1-1/+1
The actual design change is relitivly small however: It all goes back to jerry's 'BOOL store', added to many of the elements in a SAM_ACCOUNT. This ensured that smb.conf defaults did not get 'fixed' into ldap. This was a great win for admins, and this patch follows in the same way. This patch extends the concept - we don't store values back into LDAP unless they have been changed. So if we read a value, but don't update it, or we read a value, find it's not there and use a default, we will not update ldap with that value. This reduced clutter in our LDAP DB, and makes it easier to change defaults later on. Metze's particular problem was that when we 'write back' an unchanged value, we would clear any muliple values in that feild. Now he can still have his mulitivalued 'uid' feild, without Samba changing it for *every* other operation. This also applies to many other attributes, and helps to eliminate a nasty race condition. (Time between get and set) This patch is big, and needs more testing, but metze has tested usrmgr, and I've fixed some pdbedit bugs, and tested domain joins, so it isn't compleatly flawed ;-). The same system will be introduced into the SAM code shortly, but this fixes bugs that people were coming across in production uses of Samba 3.0/HEAD, hence it's inclusion here.

2002-08-20Based orginally by work by Kai, this patch moves our NT_TOKEN generation intoAndrew Bartlett1-119/+37
our authenticaion code - removing some of the duplication from the current code. This also gets us *much* closer to supporting a real SAM backend, becouse the SAM can give us the right info then. This also changes our service.c code, so that we do a VUID (rather than uid) cache on the connection struct, and do full NT ACL/NT_TOKEN checks (or cached equivilant) on every packet, for the same r or rw mode the whole share was open for.

2002-06-16Further updates to the service.c code. authorise_login() is now a bit simpilerAndrew Bartlett1-3/+1
and we seem to have eliminated the segfault. Unfortunetly I'm still at a bit of a loss as to why it did segfault, but the patch is correct in any case. Andrew Bartlett (This used to be commit 70c16188c7a267f9f3f8de0b6830f66c9e68a2c7)
2002-06-15Rework much of the service.c code:Andrew Bartlett1-95/+51
The aim of this execise is to give the 'security>=user' code a straight paper path. Security=share will sill call authorise_login(), but otherwise we avoid that mess. This allow *much* more accurate error code reporting, beocuse we don't start pretending that we can use the (nonexistant) password etc. Also in this patch is code to create the 'homes' share at session setup time (as we have done in the past - been broken recently) and to record this on the user's vuser struct for later reference. The changes here should also allow for much better use of %H (some more changes to come here). The service.c changes move a lot of code around, but are not as drastric as they look... (Also included is a fix to srv_srvsvc_nt.c where 'total_entries' not '*total_entries' was compared). This code is needs testing, but passes my basic tests. I expect we have lost some functionality, but the stuff I had expected to loose was already broken before I started. In particular, we don't 'fall back' to guest if the user cannot access a share (for security=user). If you want this kind of stuff then you really want security=share anyway. Andrew Bartlett (This used to be commit 4c0cbcaed95231f8cf11edb43f6adbec9a0d0b5c)

2002-05-25Clean up a few unused functions, add a bit of static etc.Andrew Bartlett1-1/+1
Importantly: The removal of the silly 'delete user script' behaviour when secuity=domain. I have left the name the same - as it still does the (previously documented, but not in smb.conf(5)) sane behaviour of deleting users on request. When we decide what to do with the 'add user' functionality, we might rename it. Andrew Bartlett (This used to be commit cdcfe3671eb7570e15649b77f708e6579055e7bc)
2002-05-18A few things in this commit:Andrew Bartlett1-2/+12
cleanup some of the code in net_rpc_join re const warnings and fstrings. Passdb: Make the %u and %U substituions in passdb work. This is done by declaring these paramters to be 'const' and doing the substitution manually. I'm told this is us going full circle, but I can't really see a better way. Finally these things actually seem to work properly... Make the lanman code use the pdb's recorded values for homedir etc rather than the values from lp_*() Add code to set the plaintext password in the passdb, where it can decide how to store/set it. For use with a future 'ldap password change' option, or somthing like that... Add pdb_unix, so as to remove the 'not in passdb' special cases from the local_lookup_*() code. Quite small, as it uses the new 'struct passwd -> SAM_ACCOUNT' code that is now in just one place. (also used by pdb_smbpasswd) Other: Fix up the adding of [homes] at session setup time to actually pass the right string, that is the unix homedir, not the UNC path. Fix up [homes] so that for winbind users is picks the correct name. (bad interactions with the default domain code previously) Change the rpc_server/srv_lsa_nt.c code to match NT when for the SATUS_NONE_MAPPED reply: This was only being triggered on no queries, now it is on the 'no mappings' (ie all mappings failed). Checked against Win2k. Policy Question: Should SID -> unix_user.234/unix_group.364 be considered a mapping or not? Currently it isn't.

2002-01-30Removed version number from file header.Tim Potter1-2/+1

2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-0/+2
This time its the pdb_getsampwuid() function - which was only being used by the SAMR rpc subsystem to gain a 'user session key'. This 'user session key' is actually generated at login time, and the other changes here simply move that data around. This also means that (when I check some details) we will be able to use the user session key, even when we are not actually the DC, becouse its one of the components of the info3 struct returned on logon. Andrew Bartlett (This used to be commit 799ac01fe08a338e4e94289f5d6767ebf905c1fa)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-0/+16
Samba (ab)uses the returns from getpwnam() a lot - in particular it keeps them around for a long time - often past the next call... This adds a getpwnam_alloc and a getpwuid_alloc to the collection. These function as expected, returning a malloced structure that can be free()ed with passwd_free(&passwd). This patch also cuts down on the number of calls to getpwnam - mostly by taking advantage of the fact that the passdb interface is already case-insensiteve. With this patch most of the recursive cases have been removed (that I know of) and the problems are reduced further by not using the sys_ interface in the new code. This means that pointers to the cache won't be affected. (This is a tempoary HACK, I intend to kill the password cache entirly). The only change I'm a little worried about is the change to rpc_server/srv_samr_nt.c for private groups. In this case we are getting groups from the new group mapping DB. Do we still need to check for private groups? I've toned down the check to a case sensitve match with the new code, but we might be able to kill it entirly. I've also added a make_modifyable_passwd() function, that copies a passwd struct into the form that the old sys_getpw* code provided. As far as I can tell this is only actually used in the pass_check.c crazies, where I moved the final 'special case' for shadow passwords (out of _Get_Pwnam()). The matching case for getpwent() is dealt with already, in lib/util_getent.c Also included in here is a small change to register the [homes] share at vuid creation rather than just in one varient of the session setup. (This picks up the SPNEGO cases). The home directory is now stored on the vuid, and I am hoping this might provide a saner way to do %H substitions. TODO: Kill off remaining Get_Pwnam_Modify calls (they are not needed), change the remaining sys_getpwnam() callers to use getpwnam_alloc() and move Get_Pwnam to return an allocated struct. Andrew Bartlett (This used to be commit 1d86c7f94230bc53daebd4d2cd829da6292e05da)
2002-01-02Actually enforce the passdb API.Andrew Bartlett1-1/+1
Thou shalt not reference SAM_ACCOUNT members directly - always use pdb_get/pdb_set. This is achived by making the whole of SAM_ACCOUNT have a .private member, where the real members live. This caught a pile of examples, and these have beeen fixed. The pdb_get..() functions are 'const' (have been for some time) and this required a few small changes to constify other functions. I've also added some debugs to the pdb get and set, they can be removed if requested. I've rewritten the copy_id2x_to_sam_pass() functions to use the new passdb interface, but I need the flags info to do it properly. The pdb_free_sam() funciton now blanks out the LM and NT hashes, and as such I have removed many extra 'samr_clear_sam_passwd(smbpass)' calls as a result. Finally, any and all testing is always appriciated - but the basics seem to work. Andrew Bartlett (This used to be commit d3dd28f6c443187b8d820d5a39c7c5b3be2fa95c)

members (such as uid and gid). This way we will be able to keep ourselves from writing out default smb.conf settings when the admin doesn't want to, That part is not done yet. Tested compiles with ldap/tdb/smbpasswd. Tested connection with smbpasswd backend. oh...and smbpasswd doesn'y automatically expire accounts after 21 days from the last password change either now.

(This used to be commit 507ef80f48a8fca762e41be5cdb80ce86544da3f)
2001-11-09This change updates lp_guestaccount() to be a *global* paramater, rather thanAndrew Bartlett1-5/+6
per-share. I beleive that almost all the things that this could have done on a per-share basis can be done with other tools, like 'force user'. Almost all the user's of this paramater used it as a global anyway... While this is one step at a time, I hope it will allow me to considerably simplfy the make_connection() code, particularly for the user-level security case. This already removes an absolute truckload of extra attempted password lookups on the guest account. Andrew Bartlett (This used to be commit 8e708332eded210c1d1fe0cebca3c9c19f054b71)
2001-11-08Change to guest logon code.Andrew Bartlett1-9/+9
This changes the way we process guest logons - we now treat them as normal logons, but set the 'guest' flag. In particular this is needed becouse Win2k will do an NTLMSSP login with username "", therefore missing our previous guest connection code - this is getting a pain to do as a special case all over the shop. Tridge: We don't seem to be setting a guest bit for NTLMSSP, in either the anonymous or authenticated case, can you take a look at this? Also some cleanups in the check_password() code that should make some of the debugs clearer. Various other minor cleanups: - change the session code to just take a vuser, rather than having to do a vuid lookup on vuser.vuid - Change some of the global_client_caps linking - Better debug in authorise_login(): show the vuid.

2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-19/+32
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 (This used to be commit f70fb819b2f57bd57232b51808345e2319d52f6c)
2001-10-29This commit is number 3 of 4.Andrew Bartlett1-2/+2
In particular this commit focuses on: Changing the Get_Pwnam code so that it can work in a const-enforced environment. While these changes have been mildly tested, and are pretty small, any assistance in this is appreciated. ---- These changes allow for 'const' in the Samba tree. There are a number of good reasons to do this: - I want to allow the SAM_ACCOUNT structure to move from wasteful pstrings and fstrings to allocated strings. We can't do that if people are modifying these outputs, as they may well make assumptions about getting pstrings and fstrings - I want --with-pam_smbpass to compile with a slightly sane volume of warnings, currently its pretty bad, even in 2.2 where is compiles at all. - Tridge assures me that he no longer opposes 'const religion' based on the ability to #define const the problem away. - Changed Get_Pwnam(x,y) into two variants (so that the const parameter can work correctly): - Get_Pwnam(const x) and Get_Pwnam_Modify(x). - Reworked smbd/chgpasswd.c to work with these mods, passing around a 'struct passwd' rather than the modified username (This used to be commit e7634f81c5116ff4addfb7e495f54b6bb78e8f77)

2001-08-03This is my 'Authentication Rewrite' version 1.01, mostly as submitted toAndrew Bartlett1-1072/+0
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). (This used to be commit b30b6202f31d339b48d51c0d38174cafd1cfcd42)
