When a server receives a modify operation for an entry in a part of the
DIT for which it is a slave, it issues a referral to the master.
Clients need to detect this and submit the operation to the master. The
LDAP-3.3 library includes some support for chasing referrals and
rebinding on referral, but the client tools like ldapmodify don't do
this yet. A client which wanted to implement this should set the
LDAP_OPT_REFERRALS option in the LDAP structure (it's on by default),
and should register a rebind proc using ldap_set_rebind_proc(). The
rebind proc will be called when referrals are chased and allows the
client to bind to the master before the library re-submits the modify
