We use an integrated subversion client in out software and updated from 1.6.x
to 1.8.x recently. We also use latest released version of serf, 1.3.8.
Everything is ok without proxies. But we made some tests with a proxy which
requires NTLM authentication and the checkout process breaks after a few files
with an "The handle is invalid" message. TortoiseSvn 1.8.10 is also affected.
The invalid handle error results from a call to InitializeSecurityContext in
auth_spnego_sspi.c. I think, the problem is related to the fact, that serf uses
the same authentication context for proxies for all connections, unlike the
context for server authentication. NTLM is a multiphase authentication protocol
and the responses seam to overlap which leads to problems.
We need to release our software soon, so I changed the code to store the proxy
authentication infos in the connection object as well and everything works.
Could you please investigate it?
