Lets say a client does a search (or other operation) with
DN dc=example,dc=net against against their local server (not
part of example.net).
- 
Client submits request for dc=example,dc=net to local server
 - 
Local server responds with referral ldap://root.openldap.org/
 - 
Client chases referral to root.openldap.org
 - 
root.openldap.org, based upon DNS SRV RRs, responds with a
referral to ldap://ldap.example.net/
 - 
Client chases referral to ldap.example.net.
 - 
ldap.example.net responds with appropriate results.
