I think the "jaas-config-name" should be "drools-guvnor" (the name of
the jaas configuration from the file designated by
java.security.auth.login.config).
I'm not sure what version of seam is used by guvnor; see also here:
http://docs.jboss.org/seam/2.2.2.Final/reference/en-US/html/security.html...
Hope this helps,
Nick
