OpenLDAP Server and client Configuration File

  1. /etc/openldap/slapd.conf
    1. Standalone OpenLDAP server configuration file
    2. You should set/modify the following directives
      1. rootdn - DN of the LDAP server administrator account
      2. rootpw - password for the administrator account
      3. database - what back end database to use
      4. suffix - the DN of the base directory on the LDAP server
      5. directory - where to put the database
  2. /etc/openldap/ldap.conf
    1. This is the configuration file for the ldap clients. The following are ldap client programs:
      1. ldapadd
      2. ldapcompare
      3. ldapdelete
      4. ldapmodify
      5. ldapmodrdn
      6. ldappasswd
      7. ldapsearch
      8. ldapwhoami
    2. You could set/modify the following directives:
      1. BASE
      2. URL
  3. /etc/ldap.conf
    1. This is the configuration file for the LDAP nameservice switch library and the LDAP PAM module
    2. You could set/modify the following directives:
      1. base
      2. host - IP or hostname of the LDAP server. If you use hostname, it must be resolvable without using LDAP. Multiple hosts may be specified, each separated by a space.

Important LDAP Commands and Sample LDIF files

  • Base LDIF file
  • POSIX User account file
  • ldapadd, ldapsearch, ldapdelete command

Tools/Utilities for Testing OpenLDAP Server

  • ldapsearch
    • To display LDAP Protocol features and extensions supported by OpenLDAP, use the following ldapsearch examples:

Using OpenLDAD for Apache Basic Authentication

  • In httpd.conf configure the directory for basic authentication for apache 2.0
 <Directory /var/www/html/openldap>
 AuthType Basic
 AuthName "Case Network ID"
 AuthLDAPURL "ldap://127.0.0.1/ou=people,dc=fedora,dc=directory,dc=server"
 AuthLDAPBindDN "uid=root,ou=people,dc=fedora,dc=directory,dc=server"
 AuthLDAPBindPassword "your-openldap-password"
 # All users in openldap
 require valid-user
 # Just the listed user
 # require user pma
 </Directory>
  • For apache 2.2
 <Location /var/www/html/openldap>
 AuthType Basic
 AuthBasicProvider ldap
 AuthName "Case Network ID"
 AuthzLDAPAuthoritative off
 AuthLDAPURL ldap://127.0.0.1/ou=people,dc=fedora,dc=directory,dc=server
