We let the caller use auth_generic_server_step() instead.
This allows us to request GENSEC_FEATURE_SIGN_PKT_HEADER before
starting the gensec_update() dance.

This ensures that gensec, and then the NTLM auth subsystem under it, always gets the
remote and local address pointers for potential logging.
The local address allows us to know which interface an authentication is on

The first pdu is always a BIND.
REQUEST pdus are only allowed once the authentication
is finished.
A simple anonymous authentication is finished after the BIND.
Real authentication may need additional ALTER or AUTH3 exchanges.
