The Authen::NTLM::HTTP module on CPAN has been sat there for about 5 years unmaintained, and in a namespace conflict with the 'NTLM' distribution. Unfortunately, this code is the only server side NTLM implementation on the CPAN, and I have a branch of Catalyst::Authentication::Credential::HTTP waiting for this to be fixed so it can be merged/released.
I emailed the maintainer of the module around a month ago about getting co-maint rights to fix this and maintain the code in an ongoing way, and also reported RT#44996 - but I haven't heard anything back since.
Therefore, I'm posing a public notice that I intend to follow the module takeover procedure for unresponsive authors (http://www.cpan.org/misc/cpan-faq.html#How_adopt_module).
Rather than forcibly take over the module, if anyone knows the author, can you please put me in touch with them so that I can get co-maint rights / we can get a new release out which I can actually depend on in my code.
