I have setup a new server centos 5.1 server as a storage server with over 7TB of storage. The server has been integrated into a large Active Directory network there are 5 primary AD servers and a large number of local AD server at each location (over 20). There are also over 15 trusted domains hundreds of groups and thousands of users. It has been quite a challenge to integrate the Linux server with Samba into this incitement. I am now at a point where I can change user and group ownership of filed and folders at AD users and connect to the server with a windows client. There are also issues with Samba not starting on bootup (yes the service is set to start at level 3 system starts non GUI). And it seems to take quite a while for system to recognize domain users on startup. The [TEST] share works with out issue. The [TEST-ENG] share is not working no matter what I do. The issue that I am having is that most of the groups have a @ at the beginning. Ie: @DIV-Engineering This conflicts with the Samba valid users = directive in the smb.conf. I have been able to change the group ownership to @DIV-Engineering in the file-system without any issues. Is there any way to do this?
