Metze,

In order to track document bugs properly, I will be following up on these new 
questions in two separate cases. I will start a new thread for each case:
112082370902333 SMB3 encryption of SESSION_SETUP (for reauth/or channel 
binding) and TREE_CONNECT
112082371227089 SMB3 encryption and Oplock/Lease break notifications

Thanks,
Edgar

Hi Edgar,

thanks for the answers, I have some more questions inline.

Windows doesn't complain if the client encrypt SESSION_SETUP (for reauth/or 
channel bind) and TREE_CONNECTS.

For Oplocks the server known the session from the file_id, but what session is 
used for leases?

To my understanding a lease key can be shared between sessions, is that correct?
