getting bindDN in perl script

[Benin Technologies <benintechnologies@yahoo.fr>]

Hi,

I needed to access from an LDAP client (Outlook or Thunderbird) some 
data stored in several locations (an OpenLDAP server with back-hdb, and 
a PostgreSQL database).

I wrote a perl script used with back-perl, and everything works fine. 
The client queries that back-ldap server, wich in turn retrieves data 
both from the back-hdb server and the PostgreSQL server, does some 
formatting on it, and returns it to the client

It works fine, except that I have to use a standard bindDN/password from 
the perl script to access the back-hdb server, because I don't know how 
to retrieve in that perl script the initial bindDN/password (the 
credentials provided initially by the client).

I guess there is a way to do it, because I found some links like 
http://osdir.com/ml/network.openldap.general/2002-09/msg00021.html where 
people seem to have been able to get the bindDN and password provided by 
the client, but they didn't say how and I couldn't figure it out.

Does anybody know if it's possible to get, within the perl script, the 
bindDN/password provided by the client ?

Thanks
Ben
