Verify that you have given that user permissions in the administration module. Here is my experience when I tried Guvnor 5.5 with JAAS... After I got past that namespace issue, I ran into a Seam issue where user was returning null. After searching, it seemed that was a bug in Seam security that was included in Guvnor. So, I gave up on trying to use JAAS and tried the authenticator. If you dont need the callback that JAAS provides, you have the option of trying Authenticator. If you are using tomcat, you have put your classes in the WEB-INF/classes folder. when I tried to jar and put in the lib folder, it didnt pick up the class. It is possible in your case that you just need to provide the user permissions. Hope this helps. -- View this message in context: http://drools.46999.n3.nabble.com/Drools-Guvnor-User-authentication-tp402... Sent from the Drools: User forum mailing list archive at Nabble.com.
