OpenLDAP mdb backend - openldap

Question

I try to setup an OpenLDAP Server with mdb backend. But neither the version from packet repository nor a self compiled version (to be shure that back_mdb is compiled into slapd) works for me.
Config database is accessible, log doesn't print any errors and the database file is created (data.mdb) - but my root (suffix) won't show up and isn't writeable.
A basic configuration suggested by the OpenLDAP administrator's guide won't help either.
My config:
include /etc/openldap/schema/core.schema
include /etc/openldap/schema/cosine.schema
include /etc/openldap/schema/nis.schema
include /etc/openldap/schema/inetorgperson.schema
pidfile /var/run/openldap/slapd.pid
argsfile /var/run/openldap/slapd.args
database mdb
maxsize 1073741824
suffix "dc=directory,dc=local"
rootdn "cn=admin,dc=directory,dc=local"
rootpw "{SSHA}Lh2sewmXFDo+bwc0Vqy12Xwc61n9sQ5t"
directory /var/lib/openldap/openldap-data
index objectClass eq
access to dn.subtree="ou=contacts,dc=directory,dc=local" by self write by dn="cn=server,ou=people,dc=directory,dc=local" write by dn="cn=phone,ou=people,dc=directory,dc=local" read
access to * by dn="cn=admin,dc=directory,dc=local" write by anonymous auth by dn.subtree="ou=people,dc=directory,dc=local" read by * none
database config
rootdn "cn=admin,cn=config"
rootpw "{SSHA}Lh2sewmXFDo+bwc0Vqy12Xwc61n9sQ5t"

Answer 1

I had to add the ldif to create my root dn on the localhost.
Create LDIF file:
dn: dc=directory,dc=local
dc: directory
o: directory.local
objectClass: top
objectClass: dcObject
objectClass: organization
structuralObjectClass: organization
Add the LDIF file and recreate database index:
slappadd -b "dc=directory,dc=local" -v -l basedn.ldif
slapindex
Start the ldap daemon and there it is: my root dn.
