Hi, I am running a couple of Samba / LDAP servers. While they all do work fine, I get a message like this on all of them when I run pdbedit -L -v: Unix username: administrator NT username: administrator Account Flags: [UX ] User SID: S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-21000 init_group_from_ldap: Entry found for group: 512 lookup_global_sam_rid: looking up RID 512. ldapsam_getsampwsid: Unable to locate SID [S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-512] count=0 init_group_from_ldap: Entry found for group: 512 lookup_rids: Domain Admins:2 Primary Group SID: S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-512 Full Name: Administrator I thought the "unable to locate SID message" would vanish after indexing slapd's database, but it does not. I copied the following settings for the index from the Samba Howto: # Indices to maintain ## required by OpenLDAP index objectclass eq index cn pres,sub,eq index sn pres,sub,eq ## required to support pdb_getsampwnam index uid pres,sub,eq ## required to support pdb_getsambapwrid() index displayName pres,sub,eq ## uncomment these if you are storing posixAccount and ## posixGroup entries in the directory as well index uidNumber eq index gidNumber eq index memberUid eq index sambaSID eq index sambaPrimaryGroupSID eq index sambaDomainName eq index default sub This is a new install, which is not in use yet. It is running Samba 3.0.28. The following group mappings are setup on the server: Domain Admins (S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-512) -> Domain Admins Domain Users (S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-513) -> Domain Users Domain Guests (S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-514) -> Domain Guests Domain Computers (S-1-5-21-XXXXXXXXXX-XXXXXXXXXX-XXXXXXXXXX-515) -> Domain Computers Administrators (S-1-5-32-544) -> Administrators Account Operators (S-1-5-32-548) -> Account Operators Print Operators (S-1-5-32-550) -> Print Operators Backup Operators (S-1-5-32-551) -> Backup Operators Replicators (S-1-5-32-552) -> Replicators Thanks in advance.
