Hi We have Windows 2003 AD Domain Controller and a linux servers which join in NT4-style domain. idmap is configured to use LDAP (openldap on a linux server). After we run: smbpasswd -W net join rpc -S server -U administrator /usr/sbin/smbd -D /usr/sbin/nmbd -D /usr/sbin/winbindd -D "wbinfo -u" and "wbinfo -g" get a list users and groups from a domain. if we restart all Samba processes on a server it stay working also. But when we reboot a server it stop working and produce error in winbindd log: Could not receive trustdoms So we must re-join the domain manually and restart Samba processes. What can be a problem ? We tried 3.0.30 and 3.2.0 on Slackware-12.0 with the same result. With unknown reason 3.0.31 was not able to join our domain at all. We used the same config file for all versions and made clean up before checking every version: remove /etc/smaba/private/secrets.tdb remove all files from /var/cache/samba remove the server name from AD on the domain controller Vladimir Shiray
