Problems with PAM in Samba 2.2.0?

[Norman Jordan]

I have a Samba 2.2.0 PDC set up running Linux and I have a Windows 2000 client computer. The Win2k computer can join the domain, but no one can log in. Everytime I try to logon with the Win2k computer, it says that the account is disabled. I can use the account to browse shares and mount the home directory from the PDC. I have added the account to a group on the Win2k computer.

I found the following output in syslog.
Apr 21 17:27:38 Venom smbd[7753]: [2001/04/21 17:27:38, 0] rpc_server/srv_netlog.c:api_net_sam_logon(177)
