How to skip extenstionAttribute14 and extensionAttribute15 during directory synchronization (4278317)

extensionAttribute14 and extesnionAttribute15 are the default Service Attributes that the DSA (Directory Synchronization Agent) uses to store its internal information. Any attributes which are selected as Service Attributes cannot be skipped by the DSA. 

In order to skip extensionAttribute14 and extensionAttribute15, different Service Attributes will need to be selected for the DSA to use. Any attributes selected as Service Attributes cannot be skipped. 

Service attributes can be modified by right-clicking on the Domain Pair and selecting Properties | Object Matching | Service Attributes. 

extensionAttribute14 and extensionAttribute15 are the default service attributes for Object Classes: contact, group, inetOrgPerson and user. The Auxiliary and Matching attributes for all 4 object classes which use extesnionAttribute14 and extesnionAttribute15 must be changed to use different Service Attributes.

Once the default Service Attributes are changed for the above 4 object classes, then extensionAttribute14 and extensionAttribute15 will be available to be skipped within the Properties of the Synchronization for the domain pair within Advanced Options | Attributes to Skip.
