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.
