+#  * Save the configuration: slapcat -n0 > /tmp/config.ldif
+#  * Backup slap.d:          cp -a /etc/ldap/slapd.d/ /tmp/slap.d_back
+#  * Edit the schema in /tmp/config.ldif
+#  * Load the new config:    mkdir -m 0700 /tmp/slapd.d_new && slapadd -F /tmp/slapd.d_new -n0 -l /tmp/config.ldif
+#  * Stop slapd:             /etc/init.d/slapd stop
+#  * Load the new config:    rm -rf /etc/ldap/slapd.d/ && mv /tmp/slapd.d_new /etc/ldap/slapd.d && chown -R openldap:openldap /etc/ldap/slapd.d
+#  * Create indexes:         sudo -u openldap slapindex -b 'o=mailHosting,dc=fripost,dc=dev'
