I did note that the /etc/openldap/slapd.d/cn=config folder doesn't have a database corresponding to mdb, so I'm not sure if I need to install that. This gives the following error: slapadd: could not add entry dn='cn=config' (line=1): slapadd -n 0 -F /etc/openldap/slapd.d -l /usr/share/openldap-servers/slapd.ldif I'm running this command to initialize the database, which is the same as the provided command except for the folders (which were different on my machine). OlcDbDirectory: /usr/local/var/openldap-data Here is my slapd.ldif file, which is the same as the sample one except for the domain name (redacted here): dn: olcDatabase=mdb,cn=config If you look at chapter 5.2.5.I'm trying to install OpenLDAP on Centos 7 by following the instructions here: Let's generate directory manager's password first and then open the 'chdomain.ldif' to put below text in it but make sure to replace your own domain name for 'dc=***,dc=***' section and specify the password generated for 'olcRootPW' section. In this tutorial we are going use two test servers to make the process simple using following host names and IP addresses. In the multi master replication topology, two or more than two servers can act as masters, all of these master servers are authoritative for any change in the directory server. Generate a password hash to be used as the admin password. Openldap have multiple replication configurations like Master-Master replication and Master-consumer replication are mostly used. Run the following command: root yum -y install openldap openldap-clients openldap-servers. So we have to distribiute the load of the clients with multiple servers with the help of Replication. When your directory is very big with lots of client which creates lots of traffic on the directory server then it is very difficult to meet the SLA. In this article we will be setting up Multi-Master replication of OpenLDAP server on CentOS 7.

Then access rights are evaluated by the server and when granted, the server responds with answer or maybe with a referral to another LDAP server where the client can have the query serviced. An LDAP client binds(logins) to an LDAP server that submits a query to request information or submits information to be updated. In Linux/Unix, access rights to file systems are based on file/directory permissions. In OpenLDAP access rights to address directory are based on two categories of functions in slapd, Access Control List and Authorization functions. In OpenLDAP, data information are arranged like branches of a tree, one striking difference with other varieties of commonly used databases.

It is 'lightweight' or 'smaller' when compared to the X.500 designed to run on smaller computers such as desktop computers. OpenLDAP is an open source Address Directory software.
