Hi Peter, I checked the Source of IdentityLoginModule.java and it has getUserName() method which is returning the username converted to lower case. I am not sure why after changing all the usernames on setup.txt to lowercase it still doesn't work when i try to login using the upper case user names !!! [CODE] protected String getUsername() { if (userNameToLowerCase != null && userNameToLowerCase.equalsIgnoreCase("true")) { return super.getUsername().toLowerCase(); } return super.getUsername(); } [/CODE] Thanks Mars View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4246544#...
