I'm trying to 'secure' a JBoss cluster (3 nodes) so that new nodes that are put up on the network do not join without proper authorization. I have configured the cluster-service.xml to give the cluster a unique name, so I can avoid problems with the default settings. What I would like to do, however, is secure it such that a node must pass some authorization to join (such as a username/password from an LDAP repository). I have been searching for information on the JGroups AUTH, but is seems to be few and far between (only these urls, not very useful: http://blogs.jboss.com/blog/bela/2005/12/16/JGroups_and_authentication_or... and http://wiki.jboss.org/wiki/Wiki.jsp?page=Authentication and finally, http://wiki.jboss.org/wiki/Wiki.jsp?page=JGroupsAUTH) Is there more information out there on setting this up that I'm not looking in the right place for? This seems like it should be somewhat trivial, but I can't find it... Thanks for help or pointers. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4040711#...
