Xml-rpc and Weblogic 9.2

xml-rpc with Basic Authentication works fine in Resin, but not Weblogic. This turned out to be a new feature in 9.2 which forces authentication checks when you specifically don't want one.

Basic Authentication does not work with WebLogic 9.2. (Issue #55793)

Workaround: If users do NOT want to authenticate basic authentication headers, they need to add this to their config.xml. Add this element:

<enforce-valid-basic-auth-credentials>false</enforce-valid-basic-auth-credentials> to the last line of <security-configuration> in config.xml for the users domain, usually in /bea/user_projects/domains/mydomain/config/config.xml. This keeps WebLogic from trying to authenticate basic authentication headers.
