Hi All, I have just upgraded from Samba 3.0.7 to 3.0.20 on mandrake 10.1 Before upgrading I could add a machine account and admin (root) user to the password backend, join to the domain and check the trust secret. All was well. wbinfo -a name%password would authenticate, as I require for ntlm_auth with squid (which was working well). Now with the same layout, I do this :- Add unix account for machine nimfm$:x:401:400:Machine Account:/var/lib/samba/machines:/bin/false add samba account with smbpasswd or pdbedit pdbedit -m -a -u nimfm Join the domain [root@nimfm samba]# net rpc join PDC Password: Joined domain NIMFMNET. [root@nimfm root]# wbinfo -t checking the trust secret via RPC calls failed error code was (0x0) Could not check secret Winbindd logs shows this when I do wbinfo -t [2005/11/16 21:40:14, 3] nsswitch/winbindd_misc.c:winbindd_check_machine_acct(35) [ 0]: check machine account All password checks via smbclient to a service work as expected. I have read untill my eyes blurr, checked nsswitch.conf for passwd and group winbind settings, checked the pam_winbind.so bit are where they should be. I have started from a clean slate (removing /var/cache/samba/*tdb and /etc/samba/passwd.tdb and secrets.tdb ), numerous times but get to the same point. Some funny things are happening with getent It seems that I get 2 lists of passwd or group ie the users or groups appear twice, and no Domain Groups are listed in getent group. ? This is the pdbedit output for the machine account [root@nimfm samba]# pdbedit -v nimfm$ Unix username: nimfm$ NT username: Account Flags: [W ] User SID: S-1-5-21-3407367817-49127962-788306835-1802 Primary Group SID: S-1-5-21-3407367817-49127962-788306835-515 Full Name: Machine Account Home Directory: \\nimfm\nimfm_\profile HomeDir Drive: Logon Script: Profile Path: \\nimfm\Profiles\nimfm_ Domain: NIMFMNET Account desc: Workstations: Munged dial: Logon time: 0 Logoff time: Sat, 14 Dec 1901 07:45:51 GMT Kickoff time: Sat, 14 Dec 1901 07:45:51 GMT Password last set: Wed, 16 Nov 2005 21:03:26 GMT Password can change: Wed, 16 Nov 2005 21:03:26 GMT Password must change: Sat, 14 Dec 1901 07:45:51 GMT Last bad password : 0 Bad password count : 0 Logon hours : FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF And for the auth_user account [root@nimfm samba]# pdbedit -v root Unix username: root NT username: Account Flags: [U ] User SID: S-1-5-21-3407367817-49127962-788306835-1000 Primary Group SID: S-1-5-21-3407367817-49127962-788306835-1001 Full Name: root Home Directory: \\nimfm\root\profile HomeDir Drive: Logon Script: Profile Path: \\nimfm\Profiles\root Domain: NIMFMNET Account desc: Workstations: Munged dial: Logon time: 0 Logoff time: Sat, 14 Dec 1901 07:45:51 GMT Kickoff time: Sat, 14 Dec 1901 07:45:51 GMT Password last set: Wed, 16 Nov 2005 19:13:52 GMT Password can change: Wed, 16 Nov 2005 19:13:52 GMT Password must change: Sat, 14 Dec 1901 07:45:51 GMT Last bad password : 0 Bad password count : 0 Logon hours : FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF [root@nimfm samba]# smbclient -L //NIMFM -Uroot Password: Domain=[NIMFMNET] OS=[Unix] Server=[Samba 3.0.20] Sharename Type Comment --------- ---- ------- netlogon Disk Network Logon Service Profiles Disk IPC$ IPC IPC Service (Samba Server 3.0.20) ADMIN$ IPC IPC Service (Samba Server 3.0.20) root Disk Home Directories Domain=[NIMFMNET] OS=[Unix] Server=[Samba 3.0.20] Server Comment --------- ------- NIMFM Samba Server 3.0.20 Workgroup Master --------- ------- NIMFMNET NIMFM -- Regards Greg Matheson Systems Admin NWT Pty Ltd
