Problem with SslStream when using Windows Vista

[Dave]

Hi.

When my client program runs under XP and calls a server (solaris in
this case) via an SslStream all is well. The client may make multiple
calls and multiple authentication calls and be fine. I expressly "clean up"
everything streamwise and socketwise and all is well.
Running the client under Vista, when the second authentication call is made
it returns the following SSPI error:

"A call to the SSPI failed, see inner exception"
which reads
"the Local Security Authority cannot be contacted"
Well that was pretty mystifying so I looked at what was going on with
ethereal. Apparently, on the second authentication go-round Vista asks the
server to re-use a session Id. The server responds and then
Vista rejects a re-used session Id (even though it asked to do that).
What I have found out is that the .net framework caches SslStream sessions
automatically, I have not found any way to turn this off for Vista - any
ideas on how to do this or to get Vista to use the cached SessionId which it
requested?

Here is a link to a sample that seemingly generates the same flaw that I
have described.
