Hey all, There was an issue a week ago of problem performing DNS SRV records queries from the engine, and it caused issues when working with LDAP. In order to fix these issues please make sure you copy the file: <src>/deployment/modules/sun/jdk/main/module.xml To: $JBOSS_HOME/modules/sun/jdk/main/module.xml You should do that even if you are only working with the internal domain, as one day you might try to work with LDAP one. Note that a fix for that was posted, and it is a part of the RPMs as well, so it is only relevant for people who already have this environment set up, and not for new environments. Thank you, Oved
