In case you wanna use LDAP over secured connections (TLS), you need to get/install the SSL certificates for your server. If you do not have any certifcates, you may generate a self-signed as follows: cd /etc/openldap ./gencert.sh This creates a certificate file named ldap.pem in the current working directory. It should be readable by the user 'root' and group 'ldap' and no one else. Self-signed SSL certificates are treated harshly by OpenLDAP 2.1+ add 'TLS_REQCERT never' if you want to use them. Default schemas are installed in: @CLIENT_BASEDIR@/share/openldap/schema/ Default OpenLDAP Backends can be found in: @CLIENT_BASEDIR@/lib/openldap/ If you need more information or help, please have a look at the documentation coming with the package named LNFopenldap-docs or have a look at http://www.openldap.org/ .
