== Authentication
Once a client is connected to the server, it initiates an authentication
sequence. The next figure shows the steps of the sequence:

* SaslHandshake: the client asks about the SASL mechanisms the server supports. It
can then pick one from the list the server returns.
* SaslAuthenticate: the client answers to the server's challenge(s), using the
SASL mechanism it picked. The server will send a `Tune` frame once it is satisfied
with the client authentication response.
* Tune: the server sends a `Tune` to suggest some settings (max frame size, heartbeat).
The client answers with a `Tune` with the settings he agrees on, possibly adjusted
from the server's suggestion.
* Open: the client sends a `Open` frame to pick a virtual host to connect. The server
answers whether it accepts the access or not.
