I am having a frustrating time trying to do something with Perl that would take a couple of lines of code in C#, namely to call a web service on a Windows server that requires Integrated Windows Authentication.

The most likely candidate I've found for success is a module called LWP::Authen::Ntlm, but all the examples I've googled require you to explicitly supply username, password and domain. I don't want to do that - I just want the request to use the credentials of the currently logged in user, a la CredentialCache.DefaultCredentials in .NET.

Have any of you Perl gurus out there ever had to do this?

Thanks.
