I have installed 3.4.3 on a CentOS 5.4 box as a PDC with tdbsam for a backend. All seems to be working as expected in the Samba world. With the intention of getting ordinary maintenance off of my back, I downloaded and installed usrmgr and srvmgr in /root/bin. When I launch either of them from a WinXP workstation member while logged into the domain as root, the domain is not found. I can find the domain from the menu and look at various settings, but cannot do much of anything that can be made permanent. Question: Have I omitted some critical setting to make these tools useful? Should I not be able to add users to groups, for example? What follows is some output that shows thing to be configured correctly. I think. root at foobar {~} net rpc group MEMBERS "Domain Admins" Enter root's password: PS2\root PS2\b0fh root at foobar {~} net groupmap list ... cut several local groups from this list ... Domain Users (S-1-5-21-2487701501-27877076-1099799052-513) -> staff Domain Guests (S-1-5-21-2487701501-27877076-1099799052-514) -> nobody Domain Admins (S-1-5-21-2487701501-27877076-1099799052-512) -> wheel Administrators (S-1-5-32-544) -> 10000 Users (S-1-5-32-545) -> 10001 Note: I'm not sure what the groups Administrators and Users are about. root at foobar {~} net rpc rights list Enter root's password: SeMachineAccountPrivilege Add machines to domain SeTakeOwnershipPrivilege Take ownership of files or other objects SeBackupPrivilege Back up files and directories SeRestorePrivilege Restore files and directories SeRemoteShutdownPrivilege Force shutdown from a remote system SePrintOperatorPrivilege Manage printers SeAddUsersPrivilege Add users and groups to the domain SeDiskOperatorPrivilege Manage disk shares Note: I see no priv to add users to an existing group? Thank you for your time, Ray
