Abstract

See full text

Authentication requests are redistributed among a plurality of authentication servers and to centrally managing authentication affinities among distributed servers using a secure channels affinity service. A computer system instantiates a secure channel management service configured to manage secure channel connections. The secure channel management service receives state inputs from currently deployed authentication servers. The authentication servers may be configured to queue authentication requests for transmission to authentication servers. The computer system determines that, based on the received state input, at least one of the secure channels is to be remapped to a different authentication server. The computer system also remaps the determined secure channels to distribute future authentication requests among the authentication servers. In some cases, the current state of an authentication proxy server is embedded in communications transmitted by the authentication server, such that the secure channel connections are managed using the embedded state information.
