Hi ! I made some workaround to this problem. I have moved all databases from /var/lib/samba to /var/lib/samba_lock folder, add: lock directory = /var/lib/samba_lock to smb.conf and it is working now - i can log into domain, i can browse machine list etc. but in logs i have many errors like that: lut 14 23:46:31 codo smbd[13803]: [2004/02/14 23:46:31, 0, pid=13803, effective(1002, 221), real(1002, 0)] groupdb/mapping.c:get_group_from_gid(655) lut 14 23:46:31 codo smbd[13803]: failed to initialize group mappingget_alias_user_groups: gid of user boka doesn't exist.
