2003-07-07and so it begins....Gerald Carter1-4/+198
* remove idmap_XX_to_XX calls from smbd. Move back to the the winbind_XXX and local_XXX calls used in 2.2 * all uid/gid allocation must involve winbindd now * move flags field around in winbindd_request struct * add WBFLAG_QUERY_ONLY option to winbindd_sid_to_[ug]id() to prevent automatic allocation for unknown SIDs * add 'winbind trusted domains only' parameter to force a domain member server to use matching users names from /etc/passwd for its domain (needed for domain member of a Samba domain) * rename 'idmap only' to 'enable rid algorithm' for better clarity (defaults to "yes") code has been tested on * domain member of native mode 2k domain * ads domain member of native mode 2k domain * domain member of NT4 domain * domain member of Samba domain * Samba PDC running winbindd with trusts Logons tested using 2k clients and smbclient as domain users and trusted users. Tested both 'winbind trusted domains only = [yes|no]' This will be a long week of changes. The next item on the list is winbindd_passdb.c & machine trust accounts not in /etc/passwd (done via winbindd_passdb) (This used to be commit 8266dffab4aedba12a33289ff32880037ce950a8)
2003-07-05Fixes to our LDAP/vampire codepaths:Andrew Bartlett1-0/+4
- Try better to add the appropriate mapping between UID and SIDs, based on Get_Pwnam() - Look for previous users (lookup by SID) and correctly modify the existing entry in that case - Map the root user to the Admin SID as a 'well known user' - Save the LDAPMessage result on the SAM_ACCOUNT for use in the next 'update' call on that user. This means that VL's very nice work on atomic LDAP updates now really gets used properly! - This also means that we know the right DN to update, without the extra round-trips to the server. Andrew Bartlett (This used to be commit c7118cb31dac24db3b762fe68ce655b17ea102e0)
2003-07-04This patch cleans up some of our ldap code, for better behaviour:Andrew Bartlett1-1/+1
We now always read the Domain SID out of LDAP. If the local secrets.tdb is ever different to LDAP, it is overwritten out of LDAP. We also store the 'algorithmic rid base' into LDAP, and assert if it changes. (This ensures cross-host synchronisation, and allows for possible integration with idmap). If we fail to read/add the domain entry, we just fallback to the old behaviour. We always use an existing DN when adding IDMAP entries to LDAP, unless no suitable entry is available. This means that a user's posixAccount will have a SID added to it, or a user's sambaSamAccount will have a UID added. Where we cannot us an existing DN, we use 'sambaSid=S-x-y-z,....' as the DN. The code now allows modifications to the ID mapping in many cases. Likewise, we now check more carefully when adding new user entires to LDAP, to not duplicate SIDs (for users, at this stage), and to add the sambaSamAccount onto the idmap entry for that user, if it is already established (ensuring we do not duplicate sambaSid entries in the directory). The allocated UID code has been expanded to take into account the space between '1000 - algorithmic rid base'. This much better fits into what an NT4 does - allocating in the bottom part of the RID range. On the code cleanup side of things, we now share as much code as possible between idmap_ldap and pdb_ldap. We also no longer use the race-prone 'enumerate all users' method for finding the next RID to allocate. Instead, we just start at the bottom of the range, and increment again if the user already exists. The first time this is run, it may well take a long time, but next time will just be able to use the next Rid. Thanks to metze and AB for double-checking parts of this.

2003-07-01* revert change to get_global_sam_name()Gerald Carter1-2/+23
* add get_default_sam_name() to be used by make_user_info_map() * add comments describing get_*_sam_name() (This used to be commit 90470366ea4bdb8021a3453c4bbeb29f009668c1)
2003-06-30* cleanup more DC name resolution issues in check_*domain_security()Gerald Carter1-4/+7
* is_trusted_domain() is broken without winbind. Still working on this. * get_global_sam_name() should return the workgroup name unless we are a standalone server (verified by volker) * Get_Pwnam() should always fall back to the username (minus domain name) even if it is not our workgroup so that TRUSTEDOMAIN\user can logon if 'user' exists in the local list of accounts (on domain members w/o winbind) Tested using Samba PDC with trusts (running winbindd) and a Samba 3.0 domain member not running winbindd. notes: make_user_info_map() is slightly broken now due to the fact that is_trusted_domain() only works with winbindd. disabled checks temporarily until I can sort this out.

2003-06-22Found out a good number of NT_STATUS_IS_ERR used the wrong way.Simo Sorce1-1/+1
As abartlet rememberd me NT_STATUS_IS_ERR != !NT_STATUS_IS_OK This patch will cure the problem. Working on this one I found 16 functions where I think NT_STATUS_IS_ERR() is used correctly, but I'm not 100% sure, coders should check the use of NT_STATUS_IS_ERR() in samba is ok now. Simo.

2003-06-18Ok, this patch removes the privilege stuff we had in, unused, for some time.Simo Sorce1-4/+4
The code was nice, but put in the wrong place (group mapping) and not supported by most of the code, thus useless. We will put back most of the code when our infrastructure will be changed so that privileges actually really make sense to be set. This is a first patch of a set to enhance all our mapping code cleaness and stability towards a sane next beta for 3.0 code base Simo.

2003-05-12And finally IDMAP in 3_0Simo Sorce1-238/+84
We really need idmap_ldap to have a good solution with ldapsam, porting it from the prvious code is beeing made, the code is really simple to do so I am confident it is not a problem to commit this code in. Not committing it would have been worst. I really would have been able to finish also the group code, maybe we can put it into a followin release after 3.0.0 even if it may be an upgrade problem. The code has been tested and seem to work right, more testing is needed for corner cases. Currently winbind pdc (working only for users and not for groups) is disabled as I was not able to make a complete group code replacement that works somewhat in a week (I have a complete patch, but there are bugs) Simo.

2003-05-07Set our 'global sam name' in one place. For domain controllers, this isAndrew Bartlett1-6/+8
lp_workgroup(), for all other server this is global_myname(). This is the name of the domain for accounts on *this* system, and getting this wrong caused interesting bugs with 'take ownership' on member servers and standalone servers at Snap. (They lookup the username that they got, then convert that to a SID - but becouse the domain out of the smbpasswd entry was wrong, we would fail the lookup).

2003-04-22Remove ldapsam_search_one_user_by_uid from pdb_ldap.Andrew Bartlett1-3/+2

2002-03-02This patch merges my private LDAP tree into HEAD.Andrew Bartlett1-10/+12
The main change here is to move ldap into the new pluggable passdb subsystem and to take the LDAP location as a 'location' paramter on the 'passdb backend' line in the smb.conf. This is an LDAP URL, parsed by OpenLDAP where supported, and by hand where it isn't. It also adds the ldap user suffix and ldap machine suffix smb.conf options, so that machines added to the LDAP dir don't get mixed in with people. Non-unix account support is also added. This means that machines don't need to be in /etc/passwd or in nss_ldap's scope. This code has stood up well under my production environment, so it relitivly well tested. I'm commiting this now becouse others have shown interest in using it, and there is no point 'hording' the code :-). Andrew Bartlett (This used to be commit cd5234d7dd7309d88944b83d807c1f1c2ca0460a)

2002-01-26 - Provide sid->name lookup support for non-unix accounts.Andrew Bartlett1-13/+39
- Rework the name -> sid lookup function to always try local lookup first (for local domain names) before trying winbind. This seems to eliminate my winbind feedback loop problems. (I don't use winbind for nsswitch, where there are almost certainly further issues). Andrew Bartlett (This used to be commit 25cadce67bc8effd4248ab993ae78e1d8511d994)

2002-01-20This is another *BIG* change...Andrew Bartlett1-42/+38
Samba now features a pluggable passdb interface, along the same lines as the one in use in the auth subsystem. In this case, only one backend may be active at a time by the 'normal' interface, and only one backend per passdb_context is permitted outside that. This pluggable interface is designed to allow any number of passdb backends to be compiled in, with the selection at runtime. The 'passdb backend' paramater has been created (and documented!) to support this. As such, configure has been modfied to allow (for example) --with-ldap and the old smbpasswd to be selected at the same time. This patch also introduces two new backends: smbpasswd_nua and tdbsam_nua. These two backends accept 'non unix accounts', where the user does *not* exist in /etc/passwd. These accounts' don't have UIDs in the unix sense, but to avoid conflicts in the algroitmic mapping of RIDs, they use the values specified in the 'non unix account range' paramter - in the same way as the winbind ranges are specifed. While I was at it, I cleaned up some of the code in pdb_tdb (code copied directly from smbpasswd and not really considered properly). Most of this was to do with % macro expansion on stored data. It isn't easy to get the macros into the tdb, and the first password change will 'expand' them. tdbsam needs to use a similar system to pdb_ldap in this regard. This patch only makes minor adjustments to pdb_nisplus and pdb_ldap, becouse I don't have the test facilities for these. I plan to incoroprate at least pdb_ldap into this scheme after consultation with Jerry. Each (converted) passdb module now no longer has any 'static' variables, and only exports 1 init function outside its .c file. The non-unix-account support in this patch has been proven! It is now possible to join a win2k machine to a Samba PDC without an account in /etc/passwd! Other changes: Minor interface adjustments: pdb_delete_sam_account() now takes a SAM_ACCOUNT, not a char*. pdb_update_sam_account() no longer takes the 'override' argument that was being ignored so often (every other passdb backend). Extra checks have been added in some places. Minor code changes: smbpasswd no longer attempts to initialise the passdb at startup, this is now done on first use. pdbedit has lost some of its 'machine account' logic, as this behaviour is now controlled by the passdb subsystem directly. The samr subsystem no longer calls 'local password change', but does the pdb interactions directly. This allow the ACB_ flags specifed to be transferred direct to the backend, without interference. Doco: I've updated the doco to reflect some of the changes, and removed some paramters no longer applicable to HEAD. (This used to be commit ff354c99c585068af6dc1ff35a1f109a806b326b)
2002-01-20Kill off another ugly wart from the side of the passdb subsystem.Andrew Bartlett1-33/+0
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.

conversion across to the pdb_set...() interface. Now we only set strings that are non-null. This allows Win2k to join the domain again, particularly when using tdbsam. Andrew Bartlett (This used to be commit 6d0b3d051f8f74ea6235173a89e96f5934aff4f3)
2002-01-17A nice *big* change to the fundemental way we do things.Andrew Bartlett1-4/+10
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)
2002-01-15Commit the auth associated changes I missed from the last commit.Andrew Bartlett1-0/+15
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)
2002-01-15Change the passdb interface to use allocated strings.Andrew Bartlett1-50/+75
These strings are allocated using talloc(), either using its own memory context stored on the SAM_ACCOUNT or one supplied by the caller. The pdb_init_sam() and pdb_free_sam() function have been modifed so that a call to pdb_free_sam() will either clean up (remove hashes from memory) and destroy the TALLOC_CTX or just clean up depending on who supplied it. The pdb_init_sam and pdb_free_sam functions now also return an NTSTATUS, and I have modified the 3 places that actually checked these returns. The only nasty thing about this patch is the small measure needed to maintin interface compatability - strings set to NULL are actually set to "". This is becouse there are too many places in Samba that do strlen() on these strings without checking if they are NULL pointers. A supp patch will follow to set all strings to "" in pdb_default_sam(). Andrew Bartlett (This used to be commit 144345b41d39a6f68d01f62b7aee64ca0d328085)

2002-01-02We go to a lot of effort to avoid strcpy() in Samba, but its not much use ifAndrew Bartlett1-12/+12
people start doing using strlen(src) in strncpy() :-) This occured when the talloc based passdb was reverted in favor of a pstring based one. In the talloc version this was fine, becouse the buffer was strlen(src) bytes long. This no longer applies... This doesn't seem to have broken anything, but I'm chasing up an oddity with NT password changing from the last merge.

2002-01-02Actually enforce the passdb API.Andrew Bartlett1-186/+261
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)
