My environment: CentOS4.2, Samba + openldap

I was doing below procedure to add the /etc/group to LDAP but fail:

[root@web migration]# cp /etc/group /root/group

[root@web migration]# ./migrate_group.pl /root/group > /root/group.ldif

[root@web migration]# ldapadd -x -D "cn=root,dc=wilson,dc=com" -W -f /root/group.ldif
Enter LDAP Password
adding new entry "cn=teachers,ou=Group,dc=wilson,dc=com"
ldap_add: No such object (32)
matched DN: dc=wilson,dc=com

passwd.ldif info:

dn: cn=teachers,ou=Group,dc=wilson,dc=com
objectClass: posixGroup
objectClass: top
cn: teachers
userPassword: {crypt}x
gidNumber: 521
memberUid: 521

dn: cn=students,ou=Group,dc=wilson,dc=com
objectClass: posixGroup
objectClass: top
cn: students
userPassword: {crypt}x
gidNumber: 522
memberUid: 522


ldapsearch -x -b 'dc=wilson,dc=com'

# Groups, wilson.com
dn: ou=Groups,dc=wilson,dc=com
ou: Groups
objectClass: organizationalUnit

I don't know where to be wrong
