Section Number and Name:
4.14.4.1. Connecting to custom directory information services

Describe the issue:
Two uberfire interceptor classes are shown as "business-central.war/WEB-INF/beans.xml" example configuration

<interceptors>
<class>org.uberfire.security.server.authz.cdi.RolesInterceptor</class>
<class>org.uberfire.security.server.authz.cdi.TraitInterceptor</class>
</interceptors>

These two classes are provided in "/business-central.war/WEB-INF/lib/uberfire-security-server-0.3.x-redhat-y.jar" in BPMS 6.0, But this artifact is Not available in BPMS 6.1 version.
By configuring these, it will lead to errors when starting up BPMS 6.1.

In addition, it is not explained why we need these 2 interceptors in BPMS 6.0 doc.
Is it necessary ? Why ?

Suggestions for improvement:

Confirm with developer 1) what's the purpose of these 2 interceptors in 6.0; 2) which class should we use if these are not available any more in 6.1;
and update this chapter accordingly.
