referral (1) When a server receives a search or update request from an LDAP
client that it cannot process, it usually sends back to the client a pointer to the
LDAP sever that can process the request.
(2) In the context of replication, when a read-only replica receives an update
request, it forwards it to the server that holds the corresponding read-write replica.
This forwarding process is called a referral.
