slapd Neu starten

service slapd stop
 
# Das bestehende LDAP Verzeichnis /etc/ldap/slapd.d umbenennen
mv /etc/ldap/slapd.d /etc/ldap/slapd.d.orig
 
# Das Verzeichnis wieder anlegen
mkdir /etc/ldap/slapd.d
 
# Über slaptest kann man das neue Verzeichnis mit allem Notwendigen befüllen lassen
slaptest -f /etc/ldap/slapd.conf -F /etc/ldap/slapd.d
 
# Bei Problemen
slaptest -u -f /etc/ldap/slapd.conf -F /etc/ldap/slapd.d
 
# Noch die Rechte anpassen
chown openldap:openldap -R slapd.d
chown openldap:openldap -R /var/run/slapd/
 
# Dann kann man das Service wieder starten
service slapd start

Anpassung der ldap.conf

vi ldap.conf

ldap_version 3
URI ldap://usdemo.local
SIZELIMIT 0
TIMELIMIT 0
DEREF never
BASE dc=usdemo, dc=local

Achten Sie darauf, dass der Rechner wirklich usdemo.local heißt.

Wenn noch Problem auftreten

Zum testen:

service slapd stop
slapd -u openldap -g openldap -F /etc/ldap/slapd.d -f /etc/ldap/slapd.conf -d -1
# Abbruch
service slapd start
