The Directory Proxy Server supports the ability to forward a sequence of requests to the same external server if specific conditions are met. This feature, called server affinity, is applied by the load balancing algorithms. The following server affinity methods are available in the Directory Proxy Server:
  • Client Connection. Requests from the same Directory Proxy Server client connection are consistently routed to the same external server.

  • Client IP. Directory Proxy Server client requests coming from the same client IP address are routed to the same external server.

  • Bind DN. Requests from all client connections authenticated as the same bind DN are routed to the same external server.

For each algorithm, you can specify the set of operations for which an affinity will be established, as well as the set of operations for which affinity will be used. Affinity assignments have a time-out value so that they are in effect for some period of time after the last operation that may cause the affinity to be set or updated.
