Ruby: Get currently logged in user on windows

Question

In C# I can get the current user of a web app using the HttpContext, however, I can\'t figure out how to do this in Ruby. Is there any way of doing this?

This is what worked for me but there are some limitations:

• won't work in Chrome: undefined method 'encode' for nil:NilClass
• won't validate user credentials

If you don't care about these issues, go ahead:

1. In your rails application, add Rekado's gem to your Gemfile: gem 'ntlm-sso', '=0.0.1'

2. Create an initialiser config/initializers/ntlm-sso.rb with:

   require 'rack'
   require 'rack/auth/ntlm-sso'
   
   class NTLMAuthentication
     def initialize(app)
       @app = app
     end
   
     def call(env)
       auth = Rack::Auth::NTLMSSO.new(@app)
       return auth.call(env)
     end
   end
   

3. On your application.rb file, add the line: config.middleware.use "NTLMAuthentication"

4. Call request.env["REMOTE_USER"] on your view or controller to get current username.

PS: Let me know if you find anyway to make it work on Chrome or to validate user credentials.
