When a RADIUS server receives an AAA request for a user name containing a realm, the server will reference a table of configured realms. If the realm is known, the server will then proxy the request to the configured home server for that domain. The behavior of the proxying server regarding the removal of the realm from the request ("stripping ...
The root user can do many things an ordinary user cannot, such as changing the ownership of files and binding to network ports numbered below 1024. The name root may have originated because root is the only user account with permission to modify the root directory of a Unix system.
