For tunnelling EAP types, such as TTLS and PEAP, this optional parameter specifies the User-Name that is used in the RADIUS request resulting from the EAP inner request. The default value is anonymous. Special characters can be used. %0 is replaced by the EAP identity of the inner EAP request.

This parameter is useful when proxying the inner authentication. If there is a realm in the EAPAnonymous name, it is used to choose a local Realm to handle the inner authentication.
