 # Persistent IDs can be computed on the fly with a hash, or managed in a database
 
 # For computed IDs, set a source attribute and a secret salt:
-#idp.persistentId.sourceAttribute = changethistosomethingreal
+idp.persistentId.sourceAttribute = uid
 #idp.persistentId.useUnfilteredAttributes = true
 # Do *NOT* share the salt with other people, it's like divulging your private key.
