Enable password backup for DSRM accounts

When you enable this setting, the DSRM administrator account password will be managed and backed up to Active Directory. Enabling this setting has no effect unless the managed device is a domain controller and password encryption is also enabled. If this setting is enabled, the password for the DSRM administrator account on the domain controller will be backed up to Active Directory. If this setting is disabled or not configured, the password for the DSRM administrator account on the domain controller will not be backed up to Active Directory.
