Hi all, I have a Samba PDC running on OpenSuSe 10 with LDAP as the backend and am running Mandriva 2006 as a member server with a few shares for users. The PDC seems OK and I've added the member using the instructions in the Samba example documents and I'm at the following point: OpenLDAP is running on the PDC itself. I can login to Linux as any LDAP user account suggesting that NSS Ldap is functioning correctly. Running getent passwd and getent group on the PDC provide a user and group list confirming I can set user and group ownership on any file or folder to a valid LDAP SambaSAM account and set permissions accordingly and these persmissions have the appropriate effect on user's access. The PDC's name is SMB1, the Domain is BGS. If I run net getlocalsid and net getlocasid BGS on the PDC I receive the same SID in the both cases. Smbldap-tools from Idealx.org works fine and I can add, modify and delete user's accounts from the command line without problems. The whole LDAP setup is from the idealx.org example Onto the member server (SMB2)... I've only got one domain so I'm not using Winbind relying instead on the LDAP database on the PDC. The server will authenticate UNIX users and getent returns complete user and group lists. Smb.conf uses ldapsam as the idmap backend and the second server successfully works as a BDC taking logins from clients on the network. There are three users listed as Domain Admins. If any of these users logs into a client and selects a folder or file from a shared directory on the BDC and opens the permissions tab in properties the permission on a folder shows as SMB2\Domain Admins instead of BGS\Domain Admins. If you printscreen the window as the client resolves the SID's however, the SID/RID of the SMB1/Domain Admins group is the same as the SID from the PDC (BGS/Domain Admins). If a domain admin tries to set permission on a folder, it accepts the changes but they vanish from the check boxes after it's been OK'd. The modified permissions do appear in the advanced tab though. Is there a reason for the difference in Domain names? Does it matter if the SIDs are the same? Have I missed out an important setlocalsid command? Help please, I'm getting stressed ;) Cheers, Jools
