Abstract
Techniques are described herein that are capable of dynamically routing an authentication request to a backup authentication system by a client device. For instance, the client device stores a list, which identifies authentication systems that are authorized to respond to authentication requests from the client device. The client device sends the authentication request toward a primary authentication system based at least in part on the authentication request identifying the primary authentication system as a recipient of the authentication request. The authentication request requests authentication of a principal by the primary authentication system. The client device causes the backup authentication system to authenticate the principal using an authentication package received from the primary authentication system by dynamically routing the authentication request to the backup authentication system based at least in part on not receiving a valid response to the authentication request and further based at least in part on the list.
