Does OpenLDAP provide a way to authenticate on it using a DN / pwd of

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).

Some time ago, I wrote a custom LDAP backend for hijacking authentication. My goal was to redirect it to a RADIUS server, but you could modify my code to authenticate against anything else.

For the specific case of RADIUS, a full backend is not needed. If your users already have LDAP entries, you can set their userpassword to use the {RADIUS} scheme which will cause a RADIUS server to be used for Simple Bind authentication. That code is in the contrib/slapd-modules/passwd directory in HEAD and will also be in 2.4.
