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.
