DSfW must be installed on a new OES server. The OES server can be configured on an existing SLES server or as a new install of SLES where OES is the add-on product. We recommend that you install SLES and OES together to provide update sources during the installation, to ensure that all available patches are installed in YaST before the DSfW configuration in YaST. Follow the recommendations given below:
Create separate filesystems or partitions for boot, root, tmp, swap, and var.
If you plan to use the existing password policies, ensure that the Retain existing Novell Password Policies on Users check box is selected.
Always install and configure DNS.
Replicate Schema and Configuration to all domain controllers in a domain.
