Abstract: A system and method that supports disjoint authentication server farms and disjoint policy or authorization servers for multi-session establishment. The authentication server has global knowledge of authenticators for additional sessions for a supplicant and can split authentication requests as needed to different authentication servers. The split authentication and authorization requests can be aggregated should the other authentication and authorization servers have the capability to handle multiple requests. In the case of server farms, authentication and implied authorization requests can be split to facilitate load balancing.
