was trying to get CAS to work as openID provider and use that openID provider url to login to jenkins. On my CAS side I have a server url as "http://myserver/cas-openid-server/login". However, everytime I try to user this url in jenkins using your plugin, I get this error page which says "javax.servlet.ServletException: java.lang.NoClassDefFoundError: org/openid4java/util/OpenID4JavaDOMParser". The error log doesn't say much
