The
inbound user ID is used to authorize individual messages arriving from the
foreign bus to destinations in this bus. When set, this property replaces
the user Id in messages entering this bus from the foreign bus. If this is
not a secure bus, this property has no affect on messages. You may wish to
specify an inbound user ID:
- if the foreign bus is in a different security domain from this bus and
user IDs from the foreign bus are not recognized in this bus
- to locally-control access of inbound messages to this bus.
If this is a secure bus and the foreign bus is not secure, and no inbound
user ID is set, any inbound messages from the foreign bus will only be authorized
to destinations that allow unauthenticated users access.
