Realm | A realm is a database of users with a specific name. Users can belong to multiple realms, but any given resource is protected by a single realm. For example, the administration and configuration resources are protected by the "admin" realm, whereas mail is setup by default to use another realm, named "mail".
User Name | The name of a valid existing user to attach zero or more aliases to. It may not contain a colon ":".
Alias | An alias to use for an existing user name. It must not be the same as any existing user name in this realm. It may not contain a colon ":" Common uses for aliases include aliasing "PostMaster" and "WebMaster" e-Mail ids to a single user name. This means the system administrator only needs to examine one mailbox.

Delete an Alias | Delete an existing alias.
Find Users Aliased | Lists all user names that have aliases defined.
Find Aliases of User | Lists all valid aliases for a given user name.
