Ruby Sinatra - Authenticate user against local user database (linux / mac)

Question

Is it possible to authenticate user against the local user database on linux/mac? I would like to create users locally on linux and then force authentication using sinatra or any other suggested ruby gem (no rails knowledge :()

I don't have any database and my app is so simple it should look like this:

require 'sinatra'

use Rack::Auth::Basic, "Restricted Area" do |username, password|
  [username, password] == ['admin', 'admin']
end

get '/' do
  "You're welcome"
end

My recommendation is to use a database. If you end up going that route here is how you would do it:

Add to your gemfile gem 'sqlite' and gem 'sinatra-activerecord' Run the command bundle exec rake db:create_migration NAME=setup_users_table . This will create a db directory containing migrations/<random numbers>_setup_users_table.rb . In that file, add code inside the change function. To create a Users table with a username and password field add the following code:

create_table :users do |i|
    i.string :username
    i.string :password
end

Now run bundle exec rake db:migrate . If that has succeded then you have a working database. To access it you need to add to your app file the following code:

class User < ActiveRecord::Base
end

Now you're good to go!

To create a user:

User.create(username:<whatever>,password:<whatever>)
