libvirt users - Nov 2018 - user information sent when using sasl or tls

Hello everyone!

I am trying without any success to decipher traffic from client to server
in virt-manager in wireshark, but I don't know the sessioon key there, so
seems no chance to do this.

This is why I want to ask, is any info related to the certificate sent
through the connection? Or if I use kerberos protocol for authentication,
will the user id be sent in every message from client to server? Or only
during authentication?
