Hi,

I know this topic is years old but I faced the same issue today, running the current version of OpenLDAP.

The problem can also occur when using the translucent backend.

While troubleshooting the issue, I found two possible workarounds for our setup.

1. acl-bind Instead of using idassert-bind I used acl-bind. The connection problem "Error: ldap_back_is_proxy_authz returned 0, misconfigured URI?" didn't happen anymore, but since I got different results with my search filters, it wasn't sufficient.

2. flags=3Doverride After I added the flags=3Doverride setting in the idassert-bind section the problem was gone and everything works for me. I don't know if it's a good approach but at least it works for now with our openLDAP backend server.

=2D- Regards
