Security Software

Hi,
We are running OAS 10g R2 on Win2k. Performed standard install. No tricky config.
I have been trying to load the sample_out.ldif file from the OID tutorial with the following comand

%ORACLE_HOME%/bin/ldapadd –h %OID_Host% -p %OID_Port% -D "cn=orcladmin" –w "managepassword" -v -f %SAMPLE_HOME%/sample_out.ldif

==> Result

add objectclass:
domain
add dc:
sample_users
adding new entry dc=sample_users,cn=Users,dc=eatchip, dc=eurocontrol, dc=be
ldap_add: Insufficient access

The sample_out.ldif file contains

dn: dc=sample_users,cn=Users,dc=eatchip, dc=eurocontrol, dc=be
changetype: add
objectclass: domain
dc: sample_users

dn: cn=SCOTT,dc=sample_users,cn=Users,dc=eatchip, dc=eurocontrol, dc=be
changetype: add
objectclass: inetOrgPerson
objectclass: orclUser
objectclass: orclUserV2
c: us
cn: SCOTT
givenname: Scott
uid: scott
sn: scott
manager: cn=JONES,cn=Users,dc=eatchip, dc=eurocontrol, dc=be
orclHireDate: 19-APR-87
title: Analyst
mail: SCOTT@eurocontrol.COM
userpassword: welcome1

What is wrong ?
I have figured out it was an ACP issue and read through the ACP chapter 14. And did my homework but I still getting the same error.
Google, Metalink and even this forum were helpless.
Can anyone tell me how to add Groups and Users using ldapmodify ?

Lalaina
