The server allows both NTLM and Basic (multiple WWW-Authenticate
headers are transmitted).  The client insists on using NTLM if it's
available which doesn't work properly in a reverse proxy setup (at
least as far as I understand it).

If I remove the NTLM header, the client falls back to Basic and all
works correctly.

The client is BIS (Blackberry) so unfortunately I can't change its
behavior. :)
