title: Security role to user/group mapping in WebSphere 7 with file-based user registry
body: <p>I am trying to make a form-based authentication.
  I configured my deployment descriptor correctly, did all the actions listed in IBM Infocenter related to "enabling user authentication using file-based registry only", mapped my users to appropriate roles, clicked OK, tested and it worked. But when I moved on to something else in the administrative console, I realised that there are no "OK", "Save" or "Apply" buttons in "Security role to user/group mapping", thus all my changes can take action only while I stay on that page, and as soon as I click a link in the console all the changes are instantly reset.
  I think it might be a bug in the console. Is there a solution to it? Perhaps a way to directly edit an xml file with these properties?</p>
  
  <p>Thanks in advance.</p>
