Creating the OpenLDAP server replica
Can you synchronize two LDAP directories? Replication is a mechanism allowing to copy data from one server to another automatically. After copying data from the server storing the main copy of data for servers storing other copies of this data, the mechanism of replication still synchronizes all copies on servers, i.e. changing data on the server with the right to save data results in the same changes in data copies on other servers. The micro-course describes the ways of synchronizing LDAP directories on the basis of the OpenLDAP server. The older model, realized by the slurpd server, and the newer way, done with the SyncRepl mechanism built in the server, are also shown here.

OpenLDAP server
The heart of LDAP in the Linux system is slapd. The OpenLDAP program was created on the basis of the project shared by the University of Michigan that realized access to the LDAP directory. During the development of the project two more software versions which introduced new implementations and functions were created. The micro-course describes the history and basic information about the most popular and the least complicated LDAP server for the Linux system that is the OpenLDAP. Moreover, there is information about installation and the basic way to run it. Keywords: OpenLDAP, slapd, slurpd OpenLDAP server OpenLDAP project Installation and configuration in the Linux environment Installation from sources in the Linux system Installation from binary files Running OpenLDAP
