I'm changing this bug report into an RFP bug against wnpp since it's
not libwww-perl's fault that Authen::NTLM is not yet packaged :)

Relevant info:

* Package name    : libauthen-ntlm-perl
  Version         : 0.31
  Upstream Author : Yee Man Chan (ymc at yahoo.com)
* URL             : http://search.cpan.org/dist/Authen-NTLM/
* License         : Perl (Artistic | GPL-1+)
  Programming Lang: Perl
  Description     : Perl extension for NTLM related computations

    The NTLM (Windows NT LAN Manager) authentication scheme is the
    authentication algorithm used by Microsoft.

    NTLM authentication scheme is used in DCOM and HTTP environment. It is
    used to authenticate DCE RPC packets in DCOM. It is also used to
    authenticate HTTP packets to MS Web Proxy or MS Web Server.

    Currently, it is the authentication scheme Internet Explorer chooses to
    authenticate itself to proxies/web servers that supports NTLM.

    As of this version, NTLM module only provides the client side functions
    to calculate NT response and LM response. The next revision will provide
    the server side functions that computes the nonce and verify the NTLM
    responses.

    This module was written without the knowledge of Mark Bush's (MARKBUSH)
    NTLM implementation. It was used by Yee Man Chan to implement a Perl
    DCOM client.

Hm, the last sentence is interesting. Searching CPAN for MARKBUSH and
NTLM I get to http://search.cpan.org/dist/NTLM/ which also provides
Authen:NTLM, which is newer. Information for this module:

* Package name    : libauthen-ntlm-perl
  Version         : 1.05
  Upstream Author : Mark Bush <Mark.Bush at bushnet.demon.co.uk>
* URL             : http://search.cpan.org/dist/NTLM/
* License         : weird [0]

"do not try ... to sell" and "send me any diffs" sound non-free to me.


Coming back to the original request:
lib/LWP/Authen/Ntlm.pm has
  use Authen::NTLM "1.02";
so it seems to need the second of the above mentioned modules.

If someone is interested to work on it I guess the first step would
need to be to discuss licensing with upstream ...


Cheers,
