I have a RedHat 5.2 and I have some problem with a Windows 2003 Domain. I have configured winbind (the configuration is the same and works in other installation) if I use as a password server a Windows 2000 Domain Server always works, if I use as password server a Windows 2003 Domain Server it is impossible validate on domain via ssh and I have to to turn off the Windows 2000 server. What could be different on server 2003, is the first server 2003 that does not works ... With Windows 2003 server i see users and groups with wbinfo command but if i try to connect via ssh with a domain user this is the output of /var/log/secure Dec 2 12:47:56 localhost sshd[7092]: pam_winbind(sshd:auth): [pamh: 0x09f59410] ENTER: pam_sm_authenticate (flags: 0x0001) Dec 2 12:47:56 localhost sshd[7092]: pam_winbind(sshd:auth): getting password (0x00000091) Dec 2 12:47:56 localhost sshd[7092]: pam_winbind(sshd:auth): Could not retrieve user's password Dec 2 12:47:56 localhost sshd[7092]: pam_winbind(sshd:auth): [pamh: 0x09f59410] LEAVE: pam_sm_authenticate returning 20 Dec 2 12:47:58 localhost sshd[7092]: Failed password for proj from 10.120.12.51 port 4352 ssh2 what does it mean : pam_sm_authenticate returning 20 Thanks Simone
