By I have uninstall old samba version and save and replace old /var/lib/samba/*.tdb files on new one I can't access to my samba box with new user created on NT server. The old user works fine again but if I create a new user and connect to domain and dbclick on samba-box it ask me user&password. The authentication is via winbind, is possible that any *tdb files is corrupted? Thanks, Marco.
