That's a solution, but I don't fancy the tedium of getting all my
users to change to https:// links or of setting up SSL on my apache
install. It's an internal server and I really don't care too much
about the insecure nature of NTLM over HTTP.

The trunk (1.5) has a new option for the servers file -
http-auth-types , which allows you to control which auth types the
Neon library uses on a per-server basis. That would be great for me
but I can't really go to 1.5 yet because I'm working on projects that
use 1.4 clients that have no 1.5 equivalent release yet. I had a look
at the source and the devs have chosen not to backport this to the 1.4
branch. The thread discussing this is
http://svn.haxx.se/dev/archive-2006-10/0224.shtml - Joe Orton alludes
to this in his post on the Neon list.

On the whole, I'm not too bothered - my users are used to using their
NTLM credentials over Basic. I have a feeling that some patch that IT
Services have inflicted on us may have broken mod_sspi on the server
anyway because TSVN build 7501 has stopped working for me. It's just
that niggling little splinter in your mind when something doesn't
work... :-)

I don't know whether setting http-auth-types = negotiate will force
the use of SSPI over plain HTTP though. It would be nice to find that
