Trying to place some working Samba servers in to an active directory environment, and things are not working. The server itself seems to work with other services. I am actually at the point that I can log in to my server using a valid Active directory log on, so I know Unix and Active Directory are talking. I can kinit, do "net ads join"s, it would seem the active directory part is fine. When I try an access samba shares, no luck. If I try to access my server shares via IE, it prompts for a paswrod, but never accepts it. It would seem a working implementation would never even prompt for a password, just accept my credentials. I can smbclient -L myhost -U valid_ad_account Supply a password when the prompt appears, and things work, Yet I can't do smbclient -L myhost -k After I do a valid kinit. If I make my samba pam module just pam_warn.so, I see no output, so I am guessing I don't even get that far. My major error message at smbclient -L myhost -k is session setup failed: NT_STATUS_LOGON_FAILURE Cranking up the debug level to d 3, I see lp_load: refreshing parameters Initialising global parameters params.c:pm_process() - Processing configuration file "/etc/samba/smb.conf" Processing section "[global]" added interface ip=10.155.100.175 bcast=10.155.100.255 nmask=255.255.255.0 Client started (version 3.0.2-6.3E).

Ideas?
