First of all, authzID is only useful if "mode" is not given, as specified in the man page; it's ignored in your case.

Second, the idassert-bind directive is only honored if the user authenticates, while your application is probably binding anonymously to the proxy.

If you want idassert to work also for anonymous operations (not recommended, as this defeats the security model of the remote server, by letting it believe that the proxy authenticated users while it didn't), you need to explicitly enable it using an idassert-authzFrom rule that includes anonymous, like

idassert-authzFrom "dn.regex:.*"
