free() each auth method. (We had relied on the use of talloc() only, despite providing the free() callback) Andrew Bartlett (This used to be commit 5872c0e26e3407c7c1dcf2074a36896a3ca1325a)
2003-11-22Changes all over the shop, but all towards:Andrew Bartlett4-30/+142
- NTLM2 support in the server - KEY_EXCH support in the server - variable length session keys. In detail: - NTLM2 is an extension of NTLMv1, that is compatible with existing domain controllers (unlike NTLMv2, which requires a DC upgrade). * This is known as 'NTLMv2 session security' * (This is not yet implemented on the RPC pipes however, so there may well still be issues for PDC setups, particuarly around password changes. We do not fully understand the sign/seal implications of NTLM2 on RPC pipes.) This requires modifications to our authentication subsystem, as we must handle the 'challege' input into the challenge-response algorithm being changed. This also needs to be turned off for 'security=server', which does not support this. - KEY_EXCH is another 'security' mechanism, whereby the session key actually used by the server is sent by the client, rather than being the shared-secret directly or indirectly. - As both these methods change the session key, the auth subsystem needed to be changed, to 'override' session keys provided by the backend. - There has also been a major overhaul of the NTLMSSP subsystem, to merge the 'client' and 'server' functions, so they both operate on a single structure. This should help the SPNEGO implementation. - The 'names blob' in NTLMSSP is always in unicode - never in ascii. Don't make an ascii version ever. - The other big change is to allow variable length session keys. We have always assumed that session keys are 16 bytes long - and padded to this length if shorter. However, Kerberos session keys are 8 bytes long, when the krb5 login uses DES. * This fix allows SMB signging on machines not yet running MIT KRB5 1.3.1. * - Add better DEBUG() messages to ntlm_auth, warning administrators of misconfigurations that prevent access to the privileged pipe. This should help reduce some of the 'it just doesn't work' issues. - Fix data_blob_talloc() to behave the same way data_blob() does when passed a NULL data pointer. (just allocate) REMEMBER to make clean after this commit - I have changed plenty of data structures... (This used to be commit f3bbc87b0dac63426cda6fac7a295d3aad810ecc)

* 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.

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)

down failures. Add a 'auto-add on modify' feature to guestsam Fix some segfault bugs on no-op idmap modifications, and on new idmappings that do not have a DN to tack onto. Make the 'private data' a bit more robust. Andrew Bartlett (This used to be commit 6c48309cda9538da5a32f3d88a7bb9c413ae9e8e)

2003-07-03This patch takes the work the jerry did for beta2, and generalises it:Andrew Bartlett7-44/+92
- 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* 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 Carter2-212/+59
* 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)
2003-06-30Valgrind found a bug (subtracting a pointer from a length rather than theJeremy Allison1-1/+1
length of what the pointer points to). Jeremy. (This used to be commit 492a96e9922c1ef96b967f2965f8bba1f5bc8f23)
2003-06-30* rename samstrict auth method to samGerald Carter2-58/+31
* 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 Carter3-7/+16
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)

*) consolidates the dc location routines again (dns and netbios) get_dc_list() or get_sorted_dc_list() is the authoritative means of locating DC's again. (also inludes a flag to get_dc_list() to define if this should be a DNS only lookup or not) (however, if you set "name resolve order = hosts wins" you could still get DNS queries for domain name IFF ldap_domain2hostlist() fails.
