Bind using credentials from another directory server

Hello all !

Does OpenLDAP provide a way to authenticate on it using a DN / pwd of another LDAP server ? I have read the manual page about the LDAP and META backends, but I did not find if it match my will.

At the end I would like to authenticate on OpenLDAP with a DN/pwd of another directory (or maybe SASL credentials ?), and access (probably only through OpenLDAP) to the data of both OpenLDAP and the other directory server.

I can customize the OpenLDAP server (in fact: our server), and not the other server (the customer server).

Thank you

François
