Linux File server to authenticate with AD
 

I just started at a new company and they have a Linux file server that has users authenticate using samba / openLDAP. We are a windows based environment, so every time we create a new user in AD we also have to create that user in openLDAP so that the user can access the file server. What can I do so that I dont need to create a user in LDAP and samba every time I create a new AD user. We are using centos 4.6 on the file server.

Also, we want our tier1 support to be able to add/remove/edit permissions of files and folders the way you would in windows(right click --> security tab) since the person has no linux background at all.

Look into Winbind or pam_winbind - it's component of Samba that allows it to integrate with AD logons. For permissions, you may need to enable POSIX ACLs on your filesystem (if ext3) - you can use Windows Explorer to change file/folder permissions on the samba server, but keep in mind that the Unix permissions for user, group, other are always there.
