2003-06-29Here's the code to make winbindd work on a Samba DCGerald Carter1-18/+44
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)
2003-06-21merge of the netsamlogon caching code from APPLIANCE_HEADGerald Carter1-5/+5
This replaces the universal group caching code (was originally based on that code). Only applies to the the RPC code. One comment: domain local groups don't show up in 'getent group' that's easy to fix. Code has been tested against 2k domain but doesn't change anything with respect to NT4 domains. netsamlogon caching works pretty much like the universal group caching code did but has had much more testing and puts winbind mostly back in sync between branches. (This used to be commit aac01dc7bc95c20ee21c93f3581e2375d9a894e1)
2003-05-08This puts real netlogon connection caching to winbind. This becomesVolker Lendecke1-28/+60
important once we start doing schannel, as there would be a lot more roundtrips for the second PIPE open and bind. With this patch logging in to a member server is a matter of two (three if you count the ack...) packets between us and the DC.

2003-04-21Merge from HEAD - save the type of channel used to contact the DC.Andrew Bartlett1-9/+10
This allows us to join as a BDC, without appearing on the network as one until we have the database replicated, and the admin changes the configuration. This also change the SID retreval order from secrets.tdb, so we no longer require a 'net rpc getsid' - the sid fetch during the domain join is sufficient. Also minor fixes to 'net'.

2003-04-07Winbind merges from HEAD:Andrew Bartlett1-5/+18
- fix winbindd_pam bugs - give a better error message for unauthorized access to auth_crap - show this message in wbinfo - fix spelling: privilaged -> privileged ** This changes the location of the winbindd privileged pipe ** (thanks to tpot) Andrew Bartlett (This used to be commit 92c2a33483cc9ddd1dd627224192a3023f8caff8)
2003-03-24(merge from HEAD)Andrew Bartlett1-7/+6
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)

2002-02-15Winbind cleanup.Andrew Bartlett1-2/+2
This patch fixes the segfaults I introduced in the previous conneciton caching patch. It cleans up the connection cache a *lot* - in particular it adds significant robustness to the operation. If a the DC goes down, we no longer fail the next operation - the code checks if the connection died during one of its own operations on the socket, and restarts the conneciton as required. There is still a memory leak in here somewhere - but this code also cleans up a number of these. Also added is the abilty to sepecify the domain of the 'get around restrict anonymous' user that winbind uses. Andrew Bartlett (This used to be commit 92cbefdf2783bf9dbbb2179c1b2f7cdb802d84a9)
2002-02-11A few small winbind updates:Andrew Bartlett1-10/+5
Add a connection cache to the netlogon pipe. This makes a *massive* difference to the time-per-auth. Also fix up *some* of the memory leaks in other connection caches. Add some debugging messages for the is_connected() code. I'm thinking we should get a client implementation of SMBecho and call it here - as it would allow us to always know the DC is around before we start. Down the debug level for some of the pam_winbind code - I'll probably down it further when I'm finished debugging. Andrew Bartlett (This used to be commit 49d3e476662220775ef8da7db01ea17e77e11b0b)

2002-02-05Drastic impromvents to pam_winbind.Andrew Bartlett1-30/+69
This adds code to do generic PAM -> NTSTATUS and NTSTATUS -> PAM error conversions, and uses them to make the error handling in pam_winbind sane. In particular, pam_winbind now uses PAM error codes, not silly '-1, -2 ...' stuff, and logs the NTSTATUS error that winbind now sends over the pipe. Added code to wbinfo to display these - makes a big difference in debugging winbindd. The main change here is the code to allow pam_winbind password changing to correctly stack - This code ripped from pam_unix, and the copyright attached. (Same as for all pam modules, including pam_winbind) Andrew Bartlett (This used to be commit dc1a72f896b83bc1ad3c7bf6c12c36ace3967280)

2002-01-18This is the 'winbind default domain' patch from Alexander BokovoyAndrew Bartlett1-2/+19
<a.bokovoy@sam-solutions.net>. The idea is the domain\username is rather harsh for unix systems - people don't expect to have to FTP, SSH and (in particular) e-mail with a username like that. This 'corrects' that - but is not without its own problems. As you can see from the changes to files like username.c and wb_client.c (smbd's winbind client code) a lot of assumptions are made in a lot of places about lp_winbind_seperator determining a users's status as a domain or local user. The main change I will shortly be making is to investigate and kill off winbind_initgroups() - as far as I know it was a workaround for an old bug in winbind itself (and a bug in RH 5.2) and should no longer be relevent. I am also going to move to using the 'winbind uid' and 'winbind gid' paramaters to determine a user/groups's 'local' status, rather than the presence of the seperator. As such, this functionality is recommended for servers providing unix services, but is currently less than optimal for windows clients. (TODO: remove all references to lp_winbind_seperator() and lp_winbind_use_default_domain() from smbd) Andrew Bartlett (This used to be commit 07a21fcd2311d2d9b430b99303e3532a8c1159e4)

2002-01-12Many thanks to Alexander Bokovoy <a.bokovoy@sam-solutions.net>.Andrew Bartlett1-0/+2
This work was sponsored by Optifacio Software Services, Inc. Andrew Bartlett (various e-mails announcements merged into some form of commit message below:) This patch which adds basics of universal groups support into Samba 3. Currently, only Winbind with RPC calls supports this, ADS support requires additional (possibly huge) work on KRB5 PAC. However, basic infrastructure is here. This patch adds: 1. Storing of universal groups for particular user logged into Samba software (smbd/ two winbind-pam methods) into netlogon_unigrp.tdb as array of uint32 supplemental group rids keyed as DOMAIN_SID/USER_RID in tdb. 2. Fetching of unversal groups for given user rid and domain sid from netlogon_unigrp.tdb. Since this is used in both smbd and winbindd, main code is in source/lib/netlogon_uingrp.c. Dependencies are added to AUTH_OBJ as UNIGRP_OBJ and WINBINDD_OBJ as UNIGRP_OBJ. This patch has had a few versions, the final version in particular: Many thanks to Andrew Bartlett for critics and comments, and partly rewritten code. New: - updated fetching code to changed byte order macros - moved functions to proper namespace - optimized memory usage by reusing caller's memory context - enhanced code to more follow Samba coding rules Todo: - proper universal group expiration after timeout (This used to be commit 80c2aefbe7c1aa363dd286a47d50c5d8b4595f43)
2002-01-10This changes the winbind protcol a bit:Andrew Bartlett1-21/+13
It adds a 'ping' request, just to check winbind is in fact alive It also changes winbindd_pam_auth_crap to take usernames and domain seperatly. (backward incompatible change, needs merge to 2.2, but this is not yet released code, so no workarounds) Finally, it adds some debugs and fixes a few memory leaks (uses talloc to do it).

2001-11-24This is another rather major change to the samba authenticaionAndrew Bartlett1-5/+7
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.

2001-10-31This is a farily large patch (3300 lines) and reworks most of the AuthRewriteAndrew Bartlett1-72/+15
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)
