Adds NTLM authentication to HTTP requests using the rubyntlm gem. A drop-in replacement for ruby-ntlm with NTLMv2 support.

NTLM authentication is used in Microsoft's server products, such as MS Exchange Server and IIS.

gem install net-http-ntlm

If you'd rather install net-http-ntlm using bundler, add a line for it in your Gemfile:

gem 'net-http-ntlm'

NTLM potentially uses legacy ciphers, which need to be enabled explicitly.

You can either create a custom OpenSSL profile in Ruby or load a custom SSL configuration by setting OPENSSL_CONF= before Ruby loads.

There's an example in the [Github Actions][.github/workflows/ci.yml]

require 'net/http/ntlm'
http = Net::HTTP.new('www.example.com')
request = Net::HTTP::Get.new('/')
request.ntlm_auth('User', 'Domain', 'Password')
response = http.request(request)
