What is the linking field between IAM and PowerSchool?

Several Home Base User Group members have asked which PowerSchool field will be matched against the UID in the SAML Assertion when a user logs into PowerSchool. The UID number is the unique identifier for IAM, it is stored within PowerSchool as follows:

employee => SIF_StatePrid

student => State_studentnumber

Please note that on some screens SIF_StatePrid may show up as StatePrId. It is the same thing. So for employees,  (SIF_StatePrid = StatePrID = UID)

Also note that if you see Student_number on the screen it is the same number as the state_studentnumber.  (Student_number = state_studentnumber)
