Proxy servers and IBM HTTP Server for Kerberos SSO

IBM® Engineering Lifecycle Management (ELM) deployments commonly install IBM HTTP Server as a proxy fronting server.

This configuration also works with SPNEGO, but it requires extra steps.

If you use IBM HTTP Server as a proxy server, configure WebSphere® Application Server for SPNEGO authentication before you configure Lightweight Third-Party Authentication (LTPA) to avoid unnecessary network calls.
