I have successfully setup a samba PDC with ldap backend. I am using the padl tools libnss_ldap and pam_ldap to tie in the linux users. I have setup a second PC running samba in security domain mode using the PDC as password server. Also I am using winbind idmap ldap backend to store its mappings in ou=Idmap. Now the problem: uid/gid mapping is consistent across all domain servers, except the PDC itself! I am unable to convince winbind running on the PDC to use the ldap mappings. How can I cure this? Any hints appreciated! Thank you, Roland
