Using referrals

["Tux" <csyap@starnet.gov.sg>]

Hi,

I have created 2 separate databases on 2 different ldap servers (Server 1
and Server 2, both v1.2.11 that comes with RH7). I've managed to tie the 2
database using a 3rd LDAP server (Server 3,also v1.2.11) so that a search on
the 3rd LDAP server returns results from both Server1 and Server2.

Command line [ldapsearch -b "c=sg" cn=*"] was able to return results from
both LDAP Server1 and Server 2 (through referrals). However, when performing
a ldap search on the Server3 using Outlook Express, only results from server
1 was returned. It seems that referral to server 2 is not working. I've set
the base in OE to "c=sg" (pls refer below for config)

Has anyone experienced the same problem? Am I missing any configuration on
the LDAP server or Outlook Express?

Pls advice on the steps that I need to perform in order to properly tie the
2 LDAP server and return the correct results from both server 1 and server 2
when using Outlook Express.

Pls feel free to propose other solutions to tie the 2 databases together.

Thanks.

Below are my configuration files:
