+==== grouper_members_identifiers
+
+Make sure identifiers.  (hopefully unique)
+
+When subjects are looked up, it can be a two part process (instead of N-part for N subject sources).
+
+Look at groups in group table,
+Look at grouper local entities in group table (maybe move to entities table)
+Look at subjects (including GrouperSystem, users, apps, things) in the data_field tables based on data fields that are marked as
+identifiers
+Perhaps make external calls if configured
