SecGuide 5.1: Chap. 13. UsersRolesLoginModule - problems

Sect. 13.1.5. UsersRolesLoginModule
We should provide example configuration with full class name of the login module. The class name is missing in this section.
e.g.
<deployment xmlns="urn:jboss:bean-deployer:2.0">

<!-- ejb3 test application-policy definition -->
<application-policy xmlns="urn:jboss:security-beans:1.0" name="ejb3-sampleapp">
<authentication>
<login-module code="org.jboss.security.auth.spi.UsersRolesLoginModule" flag="required">
<module-option name="usersProperties">ejb3-sampleapp-users.properties</module-option>
<module-option name="rolesProperties">ejb3-sampleapp-roles.properties</module-option>
</login-module>
</authentication>
</application-policy>

</deployment>
