Hello, I tried to use a simple ldap proxy configuration to relay the client request and the bind is transmitted. I then added the idassert-bind directive (with several settings) to force SASL EXTERNAL authentication on the backend and the bin is also prioritized in this case. I can't find the configuration that allows me to use SASL EXTERNAL authentication. TLS is present between the backend and the proxy but the proxy certificate is not used for SASL EXTERNAL authentication
