I believe I have everything setup correctly on my RH9 server running Samba 3.0.3.rc1 and openLDAP 2.1.22. I can join computers to the domain and authenticate to the domain without any problems. What I am having problems with is trying to do a group map so Domain Admins have administrative rights on the workstation when they login. I can get this to work on non LDAP setups by issuing net groupmap modify ntgroup="Domain Admins" unixgroup=ntadmins. Then when I login to the workstation as a Domain Admin member I get administrator rights to that workstation. I followed the steps in Chapter 6 of the Samba-3 by example book but it seems to be missing a couple of entries which I can't figure out. I've populated my LDAP database with IDEALX smbldap-populate. However when I login to the workstation as a Domain Admin member I don't have administrative privileges. When I issue a net groupmap list I get this. [root@massive /]# net groupmap list Domain Admins (S-1-5-21-3532146760-1190644406-3147972635-512) -> Domain Admins Domain Users (S-1-5-21-3532146760-1190644406-3147972635-513) -> Domain Users Domain Guests (S-1-5-21-3532146760-1190644406-3147972635-514) -> Domain Guests Print Operators (S-1-5-21-3532146760-1190644406-3147972635-550) -> Print Operators Backup Operators (S-1-5-21-3532146760-1190644406-3147972635-551) -> Backup Operators Replicator (S-1-5-21-3532146760-1190644406-3147972635-552) -> Replicator Domain Computers (S-1-5-21-3532146760-1190644406-3147972635-553) -> Domain Computers When I attempt to change Domain Admins I get this [root@massive /]# net groupmap modify ntgroup="Domain Admins" unixgroup=root [2004/04/30 14:49:47, 0] passdb/pdb_ldap.c:ldapsam_update_group_mapping_entry(2141) ldapsam_update_group_mapping_entry: No group to modify! Could not update group database What am I doing wrong? Where are the group mappings stored? Thanks, Chris
