CentOS - May 2009 - CentOS5 Desktops authenticating to 389 Directory Server

Hi Everyone.

I am doing some LDAP testing.  I have setup a 389 Directory Server on 
CentOS 5 and using the default schema I have populated it with a couple 
of users. I then did the configuration on the  client that I thought was 
needed to make it authenticate.

To test this I expected to be able to use id <uidNumber> of a user I had 
defined.
But I get id: 1001: No such user id: 5001: No such user

I then thought perhaps it was an LDAP permissions problem so I tried 
binding to the LDAP server using a user I know has full rights using 
these entries in /etc/openldap/ldap.conf  there was no change.

BINDDN cn=admin,dc=scms,dc=waikato,dc=ac,dc=nz
BINDPW LDAPt3st

I can query these users from a desktop that I want to use the LDAP 
server as an authentication source.

Using

* ldapsearch -x -H ldap://distilled.scms.waikato.ac.nz -b

The three files config files I am aware of are

cat /etc/openldap/ldap.conf
#

# See ldap.conf(5) for details
# This file should be world readable but not world writable.

Can anyone give me any pointers as to where I am going wrong ??  And can 
anyone confirm or deny that by default I should be able to bind 
anonymously and get the required authentication information ?

Thank you for any help you can offer.
