OUD virtualization: AddOutboundAttribute

Hi all,

I look forward a sample code or more explanation regarding "AddOutboundAttribute" that in the following Oracle Doc is described:

Oracle Fusion Middleware Configuration Reference Guide for Oracle Unified Directory 11g Release 2 PS2 (11.1.2.2.0)

and

Understanding the Proxy Functionality - 11g Release 2 (11.1.2)

e.g.

Find the groups that they are stored below ou=groups,o=myOrg and I want to use virtualization and create an AddOutboundAttribute built using

isMemberOf = {gid=%departmentNumber%,ou=groups,o=myOrg}

Is there additional information, sample or experience available regarding this task?

Thanks in advance,

Moh
