The General Properties page displays the basic attributes for a realm. To modify these properties, click the realm from the Realm Names list under the Access Control tab. Then, edit the following properties:
Choose a status of active or inactive. The default is active. This can be changed at any time during the life of the realm by selecting the Properties icon. Choosing inactive disables user access when logging in.
Allows you to add alias names for the DNS name for the realm. This attribute only accepts “real” domain aliases (random strings are not allowed).
Once you edit the properties, click Save.
