Netlogon profiles should be sync'd from Master PDC to Backup.

Reported by: Dave Loper
On Windows system, the login scripts located in the /var/samba/netlogon on the primary (PDC) server are replicated to the backup server.
Login scripts on the primary should then replicate to the backup. The first time this is run, it should backup any scripts that may exist on the backup (PDC).
Comment 1:
From the Samba documentation:
The netlogon share has to be replicated from the PDC to the BDC. This can be done manually whenever login scripts are changed, or it can be done automatically using a cron job that will replicate the directory structure in this share using a tool like rsync. The use of rsync for replication of the netlogon data is not critical to network security and is one that can be manually managed given that the administrator will make all changes to the netlogon share as part of a conscious move."
