Yes.  The master is the source of authority.  The slave only
holds a copy.

read redundancy, not write.  The LDAP/X.500 data model does not
support multiple master architectures.

If a client send an update request to a slave, the slave should
(if properly configured) refer the client to the master.   The
client then needs to chase this referral to complete the operation.
