This is an MS Access problem. Access is rarely able to
automatically discern primary or foriegn keys in ODBC
databases. I have the same problem with attaching MS SQL
Server tables, which are supposedly 100% compatible.

See Above.
You're going to have to settle for specifying the primary
key on creation of the linked table, and re-creating the
foriegn keys on the client side, or simply coding in the
referential integrity.
