Hello Pierangelo,
First, thank you for the response. I will re-test with the current stable release (2.3.32).
FYI, we chose the slapd-meta backend to allow for redundancy and work with multiple remote servers (I had read in the man page "the ldap backend is intended to proxy operations directed to a single server").
Would you have a sample configuration file for the working situtation? I never see a "simple authentication" bind go out from the OpenLDAP meta server, so something is definitely wrong on that end (either configuration or bug).
best to you, donfede

Your setup, with minor changes (the naming contexts, and the remote server is OpenLDAP as well) works just fine with current re23 and HEAD code, using either slapd-meta(5) (why?) or slapd-ldap(5) with slapo-rwm(5). So the devil must be in the details. In any case, since OpenLDAP 2.3.30 there were at least 10 fixes/ehnahcement to slapd-ldap(5) and at least 6 to slapd-meta(5), so an upgrade might help.

With minimal information as requested by the moderators multiple times. Why doesn't idassert-bind work as expected? When I try an anonymous query to an "LDAP" server via an OpenLDAP server configured as a proxy (backend meta , or backend ldap), the query fails because the OpenLDAP server does not bind (even when I try setting the "idassert-bind" option).
