Use libwin32 along with HTTP-DAV?

Hello World,

I'm currently trying to access a sharepoint server (IIS) using perl.
The server allows only login through NTLM.

First try was to create a new user agent using LWP and utilize
LWP::Authen::NTLM and put this one into HTTP-DAV. But somehow, the
implementation of Authen::NTLM (from Mark Bush) that get's used by
LWP::Authen::NTLM seems to be broken: IIS as well as APACHE returns a
500 internal server error after the first step of authorization (as
described here: http://www.innovation.ch/personal/ronald/ntlm.html).

So, I took CURL and tried --> success. So, it has to be something
wrong with the Authen::NTLM module. Comparing the authentication
headers of CURL and Authen::NTLM showed me: yes, different. I got the
first stage of authentication working now, but not yet the second
stage.

Therefore, I'd like to know:
- can I use libwin32 to authenticate via NTLM?
- if so, can I take the libwin32 object together with the HTTP-DAV
module? Has this been done before?

Thanks,

eckes
