    To check whether your username has been granted a particular role,
    enter it here:
    <form method="GET" action='<%= response.encodeURL("index.jsp") %>'>
    <input type="text" name="role" value="<%= util.HTMLFilter.filter(role) %>">
    </form>
    <br><br>

    If you have configured this app for form-based authentication, you can log
    off by clicking
    <a href='<%= response.encodeURL("index.jsp?logoff=true") %>'>here</a>.
    This should cause you to be returned to the logon page after the redirect
    that is performed.
