2002-10-12Nice *big* patch from metze.Andrew Bartlett1-9/+9
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 Bartlett1-93/+401
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.

2002-06-24Try to get security=domain at least slightly working.Andrew Bartlett1-7/+11
The previous code both had basic logic flaws in it, and some subtle issues regarding the Win2k info3 response. I've tested this against Samba (it looks like that was missed last time due to the 'called name' corruption - which broke my testsuite) and accomidated what I've seen from a info3 printout jmcd gave me. I'll get this tested fully as soon as I get my VMware going again. Andrew Bartlett (This used to be commit 87eba4c811293d2428bfb9bc36de22e66dce7f8b)
2002-06-15This patch does 2 things:Andrew Bartlett1-4/+177
It extends the 'server mutex' to conver security=server, becouse the connection race condition exists here too, and while people *should* use security=domain, some sites don't.... (This probably should be done in 2.2 as well). Also, start to actually extract and use the information that the remote server returns in the info3 struct. The server mutex code is now in a new file.

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)

2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-2/+4
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.

2002-01-15Commit the auth associated changes I missed from the last commit.Andrew Bartlett1-1/+1
Also set the default value of all the allocated strings to "" to avoid changing the interface (becouse pdb_get...() would point to a null string, rather than a null pointer and parts of samba rely on that). Andrew Bartlett (This used to be commit 5b4079f748e25f21162e21b439063249baf8dca6)
2002-01-11Back out the crazy notion that the NTLMSSP flags actually mean anything...Andrew Bartlett1-21/+21
Replace this with some flags that *we* define. We can do a mapping later if we actually get some more reliable info about what passwords are actually valid. Andrew Bartlett (This used to be commit 7f7a42c3e4d5798ac87ea16a42e4976c3778a76b)
2002-01-05I've decided to move the auth code around a bit more...Andrew Bartlett1-13/+50
The auth_authsupplied_info typedef is now just a plain struct - auth_context, but it has been modified to contain the function pointers to the rest of the auth subsystem's components. (Who needs non-static functions anyway?) In working all this mess out, I fixed a number of memory leaks and moved the entire auth subsystem over to talloc(). Note that the TALLOC_CTX attached to the auth_context can be rather long-lived, it is provided for things that are intended to live as long. (The global_negprot_auth_context lasts the whole life of the smbd). I've also adjusted a few things in auth_domain.c, mainly passing the domain as a paramater to a few functions instead of looking up lp_workgroup(). I'm hopign to make this entire thing a bit more trusted domains (as PDC) freindly in the near future. Other than that, I moved a bit of the code around, hence the rather messy diff.

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-133/+75
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.

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 Bartlett1-2/+51
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.

Make some of the code in srv_netlog_nt.c clearer, is passing an array around, so pass its lenght in is definition, not as a seperate paramater.

(This used to be commit c8b2718adfe114b74a155116c5e74f014d6df887)
2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-21/+543
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)
