When a user with an admin role logs in, they get access to functionality not available to standard users.
However, if a standard user types in the URL to one of the admin pages, they get access to it.
It appears the permissions are only checked when rendering the menus and not when executing the action.
Essentially any authenticated user can bypass authorisation.
The permissions are correctly checked when accessing the services through the Restful interface.
I'm talking about bookmarkable URL's in the format
http://localhost:7001/rma/wicket/wicket/bookmarkable/<Page class name>?pageType=ACTION&actionSingleResultsMode=REDIRECT&objectOid=<class name>:1&actionType=USER&actionOwningSpec=<class name>&actionId=<method description>&pageTitle=<page title>&actionMode=PARAMETERS
It's not the invocation that's being accessed by the bookmarkable URL, it's the form to enter the parameters.
Clicking the "OK" button on that form invokes the method.
The actual URL that causes the method invocation is
with a standard x-www-form-urlencoded post body.
