Hello! Meanwhile I could find out where the problem is, but I need help for fixing. While Linux machines have no problem with mounting a SAMBA 3.0.7 server with every possible username (existing on the samba server), I always get the following error when I try to do that from a windows-client. [2004/12/14 15:21:52, 0] auth/pampass.c:smb_pam_passcheck(810) smb_pam_passcheck: PAM: smb_pam_auth failed - Rejecting User wewerka ! The samba server is configured to use no password encryption, and the windows machines have the correct entry for enabling plaintext passwords in their registry. Also, there is no domain controller configured, the network is a trivial "workgroup". That the Windows-Machines are working correctly is assured, because they can connect to the second SAMBA server, running samba 2.0.6, also using no password encryption. If somebody could help me getting the authentification running, please. Security is absolutely not required. mfg Rainer Hantsch
