The
inbound user ID is used to authorize individual messages arriving from the
foreign bus to destinations in the local bus. Where it is defined, the inbound
user ID supersedes the user ID in messages arriving at the local bus from
the foreign bus. If the local bus is not secure, the inbound user
ID has no affect on messages. You may want to specify an inbound user ID for
the local bus when:
- The foreign bus is in a different security domain, user IDs in the foreign
bus are not recognized in the local bus
- You want to control locally access to inbound messages to the local bus.
In the case where the local bus is secure, the foreign bus is not secure,
and an inbound user ID has not been set, an inbound message from the foreign
bus is only authorized to destinations that allow unauthenticated users access.
