The problem is the following:
two users are created in the server admin panel, belonging to different users & managers groups.
It is necessary to redirect the user to a specific page depending on his group.
For authorization, a bean is used with the login() method, which returns a string with the page name. How to determine the user's group at this stage so that the page name depends on the group? The request.isUserInRole method returns the entered username.
