A with root previledges running sshd process listens on port 22. When someone tries to login via ssh, this sshd forks, chroot()s to /var/empty and changes his uid to the uid of the user sshd.
Ohh I see! There isn't "an authentication process" but an authentication process for each connection, forked on demand!
I hope this helps a bit.
