Migrate from slapd.conf to cn=config

Tip

This documentation is generic

Assumptions:

<SLAPD_CONF>

the path to the slapd.conf OpenLDAP configuration file

<SLAPD_CONF_DIR>

the path to the slapd.d folder that is going to store the future cn=config configuration

<SLAPD_USER>

the user that owns the slapd process

<SLAPD_GROUP>

the group that owns the slapd process

1. Stop OpenLDAP:

   systemctl stop slapd-ltb
   

2. Create cn=config directory:

   mkdir <SLAPD_CONF_DIR>
   

3. Convert configuration file:

   slaptest -f <SLAPD_CONF> -F <SLAPD_CONF_DIR> -d 256
   
   # set correct permissions
   chown -R <SLAPD_USER>:<SLAPD_GROUP> <SLAPD_CONF_DIR>
   find <SLAPD_CONF_DIR> -type d -exec chmod 750 {} \;
   find <SLAPD_CONF_DIR> -type f -exec chmod 640 {} \;
   

4. Update the arguments for your OpenLDAP launch command. It can be in any of these paths:

   • the systemd configuration file,

   • /etc/default/slapd,

   • /etc/sysconfig/slapd,

   • /usr/local/openldap/etc/openldap/slapd-cli.conf for OpenLDAP LTB packages

You should replace the argument: -f <SLAPD_CONF> by -F <SLAPD_CONF_DIR>

5. Start OpenLDAP:

   systemctl start slapd-ltb
