LDAP Problem

[pinguingilo]

hai all... I have Problem when configuration, error like this :

# ldapadd -x -D “cn=admin,dc=ngoprek,dc=com” -W -f /etc/openldap/ngoprek.com.ldif 
Enter LDAP Password: 
ldap_bind: Invalid DN syntax (34)
        additional info: invalid DN

Here my ngoprek.com.ldif config :

dn: dc=ngoprek,dc=com
objectclass: dcObject
objectclass: organization
o: Dk
dc: ngoprek

dn: cn=admin,dc=ngoprek,dc=com
objectclass: organizationalRole
cn: admin

Here my slapd.conf :
