3.4. Role Mapping LoginModule

If the LoginModule you are using exposes role names that you wish to map to more application specific names, then you can use the RoleMappingLoginModule. This uses a properties file to inject additional role names, and optionally replace the existing role, on authenticated subjects. This is what the security domain should look like: 
<subsystem xmlns="urn:jboss:domain:security:1.2">
    <security-domains>
        <security-domain name="jdv_security_domain">
            <authentication>
                ...
                <login-module code="org.jboss.security.auth.spi.RoleMappingLoginModule" flag="optional">
                    <module-option name="rolesProperties" value="${jboss.server.base.dir}/configuration/roles.properties" />
                    <module-option name="replaceRole" value="false" />
                </login-module>
                ...
            </authentication>
        </security-domain>
    </security-domains>
</subsystem>
