hi, i'm writting for the first time to this list. i have setup a linux+samba machine to act as a pdc. i have read the help files ,setup the smb.conf and i added users and machines trust accounts but i have problems when trying to join the domain. at the log files i get the message [2002/09/02 16:21:45, 0] smbd/service.c:make_connection(384) zam logged in as admin user (root privileges)[2002/09/02 16:23:27, 0] passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) unable to open passdb database.[2002/09/03 16:43:43, 0] passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) unable to open passdb database.[2002/09/03 16:48:35, 0] passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) unable to open passdb database.[2002/09/03 17:05:01, 0] passdb/pdb_smbpasswd.c:pdb_getsampwrid(1416) unable to open passdb database. although when i do a start->run-> \\linux_name and login as zam it says that zam is an admin when i try to login as zam when trying to join the domain the client say incorrect username or password and the unable to open database. my setup is as described to samba docs and i found that the same problem exists to winXP. my clients are win 2000. any suggestions? thanks in advance...
