5.8  Domain Access 
In addition to data, NFS and CIFS security information is also replicated between DR appliances. This allows access to 
each DR appliance joined to the same domain / forest from user or group accounts with appropriate permissions. Access 
to a given DR appliance will be denied when not joined to the same domain/forest. Make certain that all DR appliances 
are joined to the same domain, which provides access to all devices without concern for entering different permissions 
for each appliance. 
Note: CIFS and NFS protocol access is not synced between source and target DRs. It is not known what is at the 
remote site so these settings are not transferred. Before failing over, make sure the target DR is setup with the 
appropriate protocol access as required.
