Re: Use libwin32 along with HTTP-DAV?

Hi,

the main problem seems to be Authen::NTLM.

There are two packages with this name present on CPAN:
- (1) http://search.cpan.org/~buzz/NTLM-1.05/ (used along with LWP::Authen::NTLM)
- (2) http://search.cpan.org/dist/Authen-NTLM/ (not used)

I have tested both of them accessing a sharepoint (IIS6) and an APACHE server with mod_auth_sspi (http://sourceforge.net/projects/mod-auth-sspi/). And IIS and APACHE show the same behavior for each of the two packages: return a 500 internal server error in response to the Negotiate Message.

Since NTLM access works with CURL, I compared the headers sent by CURL and those sent by the perl modules. And they're way different:
the CURL headers don't seem to have anything in the DomainName- and Workstation-Fields and it's Negotiate Message is accepted by both of the servers, whereas the headers of the two perl modules both turn into the 500 internal server error.

I think, the work that needs to be done is not in the HTTP::DAV module but in the Authen::NTLM module itself.
And since module (1) above is used directly by LWP, I'd prefer to do a re-implementation of the module so that it truly matches the specification.

By the way: on several places I came through during the investigations to this topic, there was claimed that NTLM has to be re-engineered 'cause there's no specification available. But MSDN obviously has one: http://msdn.microsoft.com/en-us/library/cc236621
