This solution will show how to extend the Synchronization Service/Quick Connect connector schema for a certain system
When Synchronization Service/Quick Connect reads the schema from the connected system, it builds and internal map of object classes and associated attributes.
If some attribute is not directly associated with a certain object class, as it may be associated with an auxiliary class, Synchronization Service/Quick Connect will not display that attribute for the desired object class.
This behavior is by design.
You can modify the internal class-attribute association map by using the method described below. As a result, the attributes will be associated with the required object classes.
