Hi use your security-domain name as argument for the flushAuthenticationCache() operation. Tested with jboss-3.2.5 Your security-domain name is : ReportingServcieJAAS in this case invoke : flushAuthenticationCache("ReportingServcieJAAS") 1. start jmx-console and select jboss.security->service=JaasSecurityManager 2. select OperationName : flushAuthenticationCache and insert "ReportingServcieJAAS" as argument. 3. Invoke the operation Now your AuthenticationCache should be flushed. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4024151#...
