HOWTO utilize javax.servlet.http.HttpServletRequest isUserInRole( java.lang.String role )

Hopefully these notes will evolve into a more formal tutorial.

This example assumes user roles are stored in a database like so:

mysql> select * from VW_USER_ROLES;
+----+-----------+---------------+
| ID | LOGINNAME | ROLENAME      |
+----+-----------+---------------+
|  1 | me        | DEBUG         |
|  1 | me        | Super User    |
+----+-----------+---------------+

Currently only works with SAML 1.1
