hi i have been configuring my server following the how to manual CentOS 5.x Samba Domain Controller With LDAP

http://www.howtoforge.com/centos-5.x...h-ldap-backend

but for some reason after i get to slapcat i get an error

This is the error

[root@localhost openldap]# slapcat
bdb_db_open: Warning - No DB_CONFIG file found in directory /var/lib/ldap/otaku.local: (2)
Expect poor performance for suffix dc=otaku,dc=local.

Hi,

slapcat is looking in the wrong directory (/var/lib/ldap/otaku.local), for the database. Are you sure you're using the slapd.conf you've posted? Becaue according to that, the database directory should be /var/lib/ldap. You can use the following:
slapcat -v -f /etc/openldap/slapd.conf -l file.ldif

Yeap it was looking in the wrong file /var/lib/ldap/otaku.local i change to /var/lib/ldap
also use slapcat -v -f /etc/openldap/slapd.conf -l file.ldif it work

but now i tried to do ldapsearch -x -b "dc=otaku,dc=local" it returns it like this
it cant find the otaku.local

[root@otakudns openldap]# ldapsearch -x -b "dc=otaku,dc=local"
# extended LDIF
#
# LDAPv3
# base <dc=otaku,dc=local> with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# search result
search: 2
result: 32 No such object

It looks like that the "dn: dc=otaku,dc=local" does not exist.
Are you sure you've populated ldap with data? What was in the file you got from slapcat?

so far these are the configuration files that i have modified

------------------
/etc/hosts
------------------
# Do not remove the following line, or various programs
# that require network functionality will fail.

You didn't say if you have added the ldif file: /etc/openldap/init.ldif in ldap, but I guess you didn't.
Stop slapd and run:
Then start slapd and do your ldapsearch.

Regards

yeeeeeeeeeeeaaaa is working at last

i have to fix the int.ldif
like this so it accpeted the command: slapadd -l /etc/openldap/init.ldif
leaving the space between and in the dc area only goes the name nothing more


intfile

dn: dc=otaku,dc=local
objectclass: dcObject
objectclass: organization
o: Otaku Directory Server
dc: otaku

dn: cn=root,dc=otaku,dc=local
objectclass: organizationalRole
cn: root

Many Thanks bathory
