Marco Brizi [http://community.jboss.org/people/mbrizi] created the discussion "Re: User: null is NOT authenticated" To view the discussion, visit: http://community.jboss.org/message/571786#571786 -------------------------------------------------------------- The problem I have described was caused by a deployed application that attempt to modify configured login modules in javax.security.auth.login.Configuration. After this operation the jmx-console login module is not available anymore and the authentication is available only before the DefaultCacheTimeout period (5 mins). I hope this could help someone. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/571786#571786] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
