[MS-SMB2] does not contain a crisp definition of what the term "application" refers to.

To us, the term "application" somehow suggests that there is an API that an application living in userland can trigger a re-authentication.

Or does the term "application" apply to some Windows internal software like winlogon.exe and there is no publicly available API?

Just want to make sure we get the term "application" right in this context. It would be beneficial for our testing to be able to trigger a re-authentication any time via an API.
