I agree with you, and this is a big security concern at many places BTW,
since it's easy to share keep-alive connections with a proxy with only
one auth.

Some people told me they already got NTLM to work over closed connections
on the server side. I find this strange, though maybe in some setups it
only needs the client's challenge in return to validate both the request
and the session at the same time. I don't know well NTLM auth so I may say
silliness. However, if you want you can try with "option http-server-close"
instead of "option httpclose" and see if it works. But I tend to think that
the connection really has to be maintained, so it should not work. At least
it's easy to test.

Cheers,
Willy
