OpenLDAP Faq-O-Matic: Does slapd(8) support multi-master replication?

	OpenLDAP Faq-O-Matic : OpenLDAP Software FAQ : Does slapd(8) support multi-master replication?
	No (excepting dead experimental code) in all releases prior to 2.4. Kurt@OpenLDAP.org, quanah@openldap.org
	slapd(8) provides the single-master replication semantics promised by the X.500/LDAP service model, which ensures the directory service manages concurrency of update operations. Use of multi-master replication, as provided in some directory vendors, may lead to permanent inconsistencies in directory information which may harm directory applications which expect the X.500/LDAP's single-master service model. See the Internet-Draft draft-zeilenga-ldup-harmful-xx.txt for a discussion in this area. Kurt@OpenLDAP.org
	OpenLDAP 2.4 has support for multi-master replication using syncrepl, which addresses many of the concerns Kurt raised. It requires reliable clock syncronization (e.g. NTP) between the participating servers. quanah@openldap.org, hyc@openldap.org
