* move rid allocation into IDMAP. See comments in _api_samr_create_user() * add winbind delete user/group functions I'm checking this in to sync up with everyone. But I'm going to split the add a separate winbindd_allocate_rid() function for systems that have an 'add user script' but need idmap to give them a RID. Life would be so much simplier without 'enable rid algorithm'. The current RID allocation is horrible due to this one fact. Tested idmap_tdb but not idmap_ldap yet. Will do that tomorrow. Nothing has changed in the way a samba domain is represented, stored, or search in the directory so things should be ok with previous installations. going to bed now.

2003-07-07and so it begins....Gerald Carter1-48/+17
* 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)
2003-07-06This changes our Unix primary GID behaviour back to what most people expect:Andrew Bartlett1-6/+2
Samba will now use the user's UNIX primary group, as the primary group when dealing with the filesystem. The NT primary group is ignored in unix. For the NT_TOKEN, the primary group is the NT priamry group, and the unix primary group is added to the NT_TOKEN as a supplementary group. This should fix bug #109, but will need to be revisited when we get a full NT group database. Also in this commit: - Fix debug statements in service.c - Make idmap_ldap show if it's adding, or modifying an existing DN - Make idmap_ldap show both the error message and error string (This used to be commit 32e455a714b2090fcfd1f6d73daccf600c15d51b)
2003-07-03This patch takes the work the jerry did for beta2, and generalises it:Andrew Bartlett1-19/+60
- The 'not implmented' checks are now done by all auth modules - the ntdomain/trustdomain/winbind modules are more presise as to what domain names they can and cannot handle - The become_root() calls are now around the winbind pipe opening only, not the entire auth call - The unix username is kept seperate from the NT username, removing the need for 'clean off the domain\' in parse_net.c - All sid->uid translations are now validated with getpwuid() to put a very basic stop to logins with 'half deleted' accounts. Andrew Bartlett (This used to be commit 85f88191b9927cc434645ef4c1eaf5ec0e8af2ec)
2003-07-01* fixed volker's wbinfo -a lockup again. This one was my fault.Gerald Carter1-1/+44
It was caused by the winbind_ping() call in is_trusted_domain() o if we are a DC then we check our own direct trust relationships we have to rely on winbindd to update the truatdom_cache o if we are a domain member, then we can update the trustdom_cache ourselves if winbindd is not there (This used to be commit 22dfcafb37f7109dc455f4fb6323a25ba4f097bc)
2003-07-01* revert change to get_global_sam_name()Gerald Carter1-9/+5
* 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)
2003-07-01* fix the trustdom_cache to work when winbindd is not running.Gerald Carter1-3/+0
smbd will update the trustdom_cache periodically after locking the timestamp key (This used to be commit 7bc4b65b91f98271089335cc301146d5f0c76c3a)
2003-06-30* cleanup more DC name resolution issues in check_*domain_security()Gerald Carter1-3/+8
* 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. (This used to be commit e1d6094d066d4c16ab73075caba40a1ae6c56b1e)
2003-06-30* rename samstrict auth method to samGerald Carter1-2/+2
* rename original sam auth method to sam_ignoredomain * remove samstrict_dc auth method (now covered by 'sam') * fix wbinfo -a '...' and getent passwd bugs when running winbindd on a samba PDC (reported by Volker) (This used to be commit 52166faee793d337e045d64f7cb27ea7ac895f60)
2003-06-29Here's the code to make winbindd work on a Samba DCGerald Carter1-3/+5
to handle domain trusts. Jeremy and I talked about this and it's going in as working code. It keeps winbind clean and solves the trust problem with minimal changes. To summarize, there are 2 basic cases where the deadlock would occur. (1) lookuping up secondary groups for a user, and (2) get[gr|pw]nam() calls that fall through the NSS layer because they don't exist anywhere. o To handle case #1, we bypass winbindd in sys_getgrouplist() unless the username includes the 'winbind separator'. o Case #2 is handled by adding checks in winbindd to return failure if we are a DC and the domain matches our own. This code has been tested using basic share connections, domain logons, and with pam_winbind (both with and without 'winbind use default domain'). The 'trustdomain' auth module should work as well if an admin wants to manually create UNIX users for acounts in the trusted domains. Other misc fixes: * we need to fix check_ntlm_password() to be able to determine if an auth module is authoritative over a user (NT_STATUS_WRONG_PASSWORD, etc...). I worked around my specific situation, but this needs to be fixed. the winbindd auth module was causing delays. * fix named server mutex deadlock between trust domain auth module and winbindd looking up a uid * make sure SAM_ACCOUNT gets stored in the server_info struct for the _net_sam_logon() reply. Configuration details: The recommended method for supporting trusts is to use winbind. The gets us around some of the server mutex issues as well. * set 'files winbind' for passwd: and group: in /etc/nsswitch.conf * create domain trusts like normal * join winbind on the pdc to the Samba domain using 'net rpc join' * add normal parameters to smb.conf for winbind * set 'auth method = guest sam winbind' * start smbd, nmbd, & winbindd Problems that remain: * join a Windows 2k/XP box to a Samba domain. * create a 2-way trust between the Samba domain and an NT domain * logon to the windows client as a user from theh trusted domain * try to browse server in the trusted domain (or other workstations). an NT client seems to work ok, but 2k and XP either prompt for passwords or fail with errors. apparanently this never got tested since no one has ever been able to logon as a trusted user to a Samba domain from a Windows client. (This used to be commit f804b590f9dbf1f0147c06a0a2f12e221ae6fc3b)
2003-06-28add check for NT_STATUS_NOT_IMPLEMENTED in auth check so thatGerald Carter1-21/+10
map to guest = bad user works again when "trustdomain" is listed as last auth method. Also clean up some more DC location calls. (This used to be commit 77a5b1032f39b8d20925721b719fdcfff910cb06)
2003-06-22Found out a good number of NT_STATUS_IS_ERR used the wrong way.Simo Sorce1-4/+4
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.

from the PDC as a mapping to the uid we got from getpwnam in the local idmap. This should not be worse than the current state, so I decided to commit it. It is different from abartlet's preliminary patch, but I believe this is the better solution. Feel free to comment and/or revert it.

2003-05-12And finally IDMAP in 3_0Simo Sorce1-21/+22
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. (This used to be commit 0e58085978f984436815114a2ec347cf7899a89d)
2003-04-24Merge auth changes from HEAD:Andrew Bartlett1-24/+7
- better error codes than NT_STATUS_UNSUCCESSFUL for domain logon errors - make auth_winbind load the ntdomain module if winbind isn't there. - use new trusted domains cache to determine if the domain is valid. Andrew Bartlett (This used to be commit ec8d6524c6b0c70927a2b57aab71d9e3a7f8a150)
2003-03-24(merge from HEAD)Andrew Bartlett1-0/+3
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. Andrew Bartlett (This used to be commit ec071ca3dcbd3881dc08e6a8d7ac2ff0bcd57664)
2003-02-24Merge of server-side authentication changes to 3.0:Andrew Bartlett1-26/+47
- user_ok() and user_in_group() now take a list of groups, instead of looking for the user in the members of all groups. - The 'server_info' returned from the authentication is now kept around - in future we won't copy the sesion key, username etc, we will just referece them directly. - rhosts upgraded to use the SAM if possible, otherwise fake up based on getpwnam(). - auth_util code to deal with groups upgraded to deal with non-winbind domain members again.

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.
