Abstract
A method is disclosed for determining the authentication capabilities of a supplicant before initiating an authentication conversation with a client, for example, using Extensible Authentication Protocol (EAP). In one aspect, the method provides for sending, to a supplicant that is requesting access to a computer network subject to authentication of a user of the supplicant, a list of first authentication methods that are supported by an authentication server; receiving, from the supplicant, a counter-list of second authentication methods that are supported by the supplicant; determining how many second authentication methods in the counter-list match the first authentication methods; and performing an authentication policy action based on how many of the second authentication methods match the first authentication methods. Policy actions can include blocking access, re-directing to sources of acceptable authentication methods, granting one of several levels of network access, etc.
