Methods, apparatus, systems and computer program products are described and claimed that provide for automatically and positively determining that an associate accessing a business domain/application using an application-specific associate identifier is the same associate that is accessing another business domain/application using another application-specific associate identifier. Once the positive determination of same associate is made, a federated identifier key is generated and applied to all of the platforms in which the associate can be positively identified, so as to globally identify the associates across multiple enterprise-wide domains/applications. As such, the present invention eliminates the need to manually analyze associate data to determine if an associate interfacing with one domain/application is the same associate interfacing with another domain/application.
