SYMPTOMS
Microsoft Internet Authentication Server (RADIUS) can be used to authenticate remote dial-in users from another domain if the Radius server's domain trusts the user's domain.
To successfully authenticate users from a domain other than the RADIUS server's domain, the user name supplied should be in the form of domain\user and the Radius server's domain should trust the user's domain.
However, when you dial into a Routing and Remote Access server that is using a Radius server for authentication, cross-domain authentication may fail even when you specify the user name in the domain\user format.
