I'm using a scanner tool from IBM about the configuration settings in WAS6.1. It is running on AIX 5.3, but when I run it I get an error. The name of the tool is: IBM Security Configuration Scanner for WebSphere Application Server, tool version 1.0

The error occurs when it hits the 3: Certificate Checker, processing key store: NodeDefaultKeyStore:
