2007-10-10r4286: Give back 8 byte lm_session_key in Netrsamlogon-reply.Günther Deschner1-1/+1
The old #ifdef JRATEST-block was copying 16 bytes and thus overwriting acct_flags with bizarre values, breaking a lot of things. This patch is successfully running in a production environment for quite some time now and is required to finally allow Exchange 5.5 to access another Exchange Server when both are running on NT4 in a samba-controlled domain. This also allows Exchange Replication to take place, Exchange Administrator to access other Servers in the network, etc. Fixes Bugzilla #1136. Thanks abartlet for helping me with that one.

2007-10-10r1492: Rework our random number generation system.Andrew Bartlett1-1/+1
On systems with /dev/urandom, this avoids a change to secrets.tdb for every fork(). For other systems, we now only re-seed after a fork, and on startup. No need to do it per-operation.

2003-12-31Changes to our PAM code to cope with the fact that we can't handle someAndrew Bartlett1-13/+35
domains (in particular, the domain of the current machine, if it is not a PDC) By changing the error codes, we now return values that PAM can correctly use for better stacking of PAM modules - in particular of the password change module. This allows pam_winbind to co-exist with other pam modules for password changes. Andrew Bartlett (This used to be commit 6a8cc7f0122ac4dd5b10ff1160735ef1a177d448)

2003-12-30Try to gain a bit more consistancy in the output of usernames from ntlm_auth:Andrew Bartlett1-0/+26
Instead of returning a name in DOMAIN\user format, we now return it in the same way that nsswtich does - following the rules of 'winbind use default domain', in the correct case and with the correct seperator. This should help sites who are using Squid or the new SASL code I'm working on, to match back to their unix usernames.

2003-11-22Changes all over the shop, but all towards:Andrew Bartlett1-2/+8
- 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)

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.

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'.

2003-03-24(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'.
