For login, you should upgrade your server to Samba 4.7.4 and add json 
auth logging with the auth_json_audit parameter [1].

For logout, it won't be really possible to have a definitive information 
from the AD point of view. But you can probably script something on your 
desktop and send it back to the server (if the network connection is 
still up...)
