openLDAP ldap_add: No such object (32)


I've been getting this error when importing users in the openldap db:
ldapsrv1:~# ldapadd -x -W -D "cn=admin,dc=ldapsrv1,dc=csaa,dc=com" -f ~/group.ldif
Enter LDAP Password:
adding new entry "cn=root,ou=Group,dc=ldapsrv1,dc=csaa,dc=com"
ldap_add: No such object (32)
matched DN: dc=ldapsrv1,dc=csaa,dc=com

Can someone please advise?
Cheers!
DB

You should post the ldif file and maybe slapd.conf, because without them we cannot diagnose what the problem is

Thanks for the reply.

Here are a few entries in my group ldif:
dn: cn=root,ou=Group,dc=ldapsrv1,dc=csaa,dc=com
objectClass: posixGroup
objectClass: top
cn: root
userPassword: {crypt}x
gidNumber: 0

dn: cn=daemon,ou=Group,dc=ldapsrv1,dc=csaa,dc=com
objectClass: posixGroup
objectClass: top
cn: daemon
userPassword: {crypt}x
gidNumber: 1

Here's my slapd.conf:

First of all you haven't define a password for rootdn. Are you sure you want this?

You have to add first the following 2 DNs, before adding users:
dc=ldapsrv1,dc=csaa,dc=com
ou=Group,dc=ldapsrv1,dc=csaa,dc=com

Where and how would I define the password for rootdn? I have defined one password in admin when I did the initial setup dpkg-reconfigure slapd

Where would I add the 2 following DNs you mentioned?
Please advise.

Thanks mate!

In slapd.conf, along with rootdn there should be also a rootpw entry for the administrator.
When you run ldap commands, like ldapadd, with the -W option it asks you for a password which in turn is compared with rootpw. To create one (since you use crypt) run:
Code:
slappasswd -h {CRYPT}
Give the password you want twice and copy/paste the output in rootpw in slapd.conf:
Code:
rootdn "cn=admin,dc=ldapsrv1,dc=csaa,dc=com"
rootpw {CRYPT}blahblah
Then you can restart slapd.

Before adding users, groups etc, you must first create the basedn, that is "dn: dc=ldapsrv1,dc=csaa,dc=com" in your case, as the directory tree is hierarchical. Also you have to add "dn: ou=Group,dc=ldapsrv1,dc=csaa,dc=com" in order to add users under that dn.
So you have to use a ldif with something like:
Code:
dn: dc=ldapsrv1,dc=csaa,dc=com
objectClass: top
objectClass: dcObject
objectClass: organization
o: ldapsrv1
dc: ldapsrv1

dn: ou=Group,dc=ldapsrv1,dc=csaa,dc=com
objectClass: top
objectClass: organizationalUnit
ou: Group
You can take a look at this tutorial for more info.

Sorry but this is where I'm confused about.
Where would I create the basedn you stated?
I created an ldif file called people_group.ldif with these values:
dn: dc=ldapsrv1,dc=csaa,dc=com
objectClass: top
objectClass: dcObject
objectClass: organization
o: ldapsrv1
dc: ldapsrv1

dn: ou=People,dc=ldapsrv1,dc=csaa,dc=com
objectClass: top
objectClass: organizationalUnit
ou: People

dn: dc=ldapsrv1,dc=csaa,dc=com
objectClass: top
objectClass: dcObject
objectClass: organization
o: ldapsrv1
dc: ldapsrv1

dn: ou=Group,dc=ldapsrv1,dc=csaa,dc=com
objectClass: top
objectClass: organizationalUnit
ou: Group

I'm basically migrating my current unix users from an old server and copying them on to our ldap server following this tutorial:
http://www.debuntu.org/ldap-server-a...x-ldap-clients

These commands on where I get stuck:
# ldapadd -x -W -D "cn=admin,dc=ldapsrv1,dc=csaa,dc=com" -f ~/group.ldif
# ldapadd -x -W -D "cn=admin,dc=ldapsrv1,dc=csaa,dc=com" -f ~/passwd.ldif

I get this error when initiating the above commands:
root@ldapsrv1:~# ldapadd -x -W -D "cn=admin,dc=ldapsrv1,dc=csaa,dc=com" -f ~/group.ldif
Enter LDAP Password:
adding new entry "cn=admin,dc=ldapsrv1,dc=csaa,dc=com"
ldap_add: No such object (32)
matched DN: dc=ldapsrv1,dc=csaa,dc=com

Have you created and added the people_group.ldif? It must be done first according to the tutorial you've used.
Also run:
Code:
ldapsearch -x -z 100 -b 'dc=ldapsrv1,dc=csaa,dc=com' '(objectclass=*)' -D "cn=admin,dc=ldapsrv1,dc=csaa,dc=com" -W
to see if you already have an entry for the basedn?
What happens if you give a wrong password when prompted?
