just wanted to let anyone interested know that there was slight updated made to the wiki detailing some configuration differences between using this plug in with a JBoss AS server installed via the ZIP file, versus the JBoss AS server installed via the JBoss Installer jar. You can view the updated instructions (basically just step 3) at http://wiki.jboss.org/wiki/Wiki.jsp?page=NegotiateKerberos View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3964141#...
