An SSL handshake failure occurs with $WS* HTTP headers in an HTTP binding for WebSphere Process Server (WPS) or WebSphere Enterprise Service Bus (WESB)

Troubleshooting


Problem

When WebSphere Process Server and WebSphere Enterprise Service Bus applications do a handshake with another application on a different Websphere Application Server, an SSL handshake failure occurs.

Symptom

The following exception exists in the log file:
SECJ0056E: Authentication failed for reason No Client Certificate Available

Cause

$WS* headers are standard HTTP headers, such as $WSAT, which stores the Auth Type that is being used to make the request. There are other $WS* headers, such as $WSCC, $WSCS, $WSIS, and $WSSC. By default, the WebSphere Process Server and WebSphere Enterprise Bus HTTP binding will not refactor these $WS* header values when they pass through the process. If the Propagate HTTP header option is enabled, WebSphere Process Server and WebSphere Enterprise Service Bus propagate them from export to import.

The HTTP binding code for WebSphere Process Server and WebSphere Enterprise Service Bus does not refactor the value in the $WS* header. When the handshake takes place with other applications on a different server, the authentication information in the $WS* header is used. This scenario causes the handshake failure.

Resolving The Problem
