Ldap Slapd Failed

Hallo alle Linux Freunde danke schonmal fürs lesen und antworten...

Ich habe folgendes Problem mit meinem LDAP Server wenn ich ihn starten will unter Debian Lenny

Starting OpenLDAP: slapd - failed.
The operation failed but no output was produced. For hints on what went
wrong please refer to the system's logfiles (e.g. /var/log/syslog) or
try running the daemon in Debug mode like via "slapd -d 16383" (warning:
this will create copious output).

Below, you can find the command line options used by this script to
run slapd. Do not forget to specify those options if you
want to look to debugging output:
slapd -g openldap -u openldap -f /etc/ldap/slapd.conf

meine slapd.conf datei sieht so aus:

include /etc/ldap/schema/core.schema
include /etc/ldap/schema/cosine.schema
include /etc/ldap/schema/inetorgperson.schema
include /etc/ldap/schema/nis.schema
include /etc/ldap/schema/samba.schema

pidfile /var/run/ldap/slapd.pid
argsfile /var/run/slapd.args

modulepath /usr/lib/ldap
moduleload back_ldbm
backend ldbm

schemacheck on
loglevel 0
database ldbm
