OmnideskAuth

Add this line to your application's Gemfile:

gem 'omnidesk_auth'

And then execute:

$ bundle

Or install it yourself as:

$ gem install omnidesk_auth

# config/initializers/omnidesk_auth.rb
OmnideskAuth.configure do |auth|
  auth.endpoint = 'http://mycompany.omnidesk.ru'
  auth.secret = '<secret token>'
end

Note: The OmnideskAuth module takes the configuration defaults from environment variables:

• OMNIDESK_AUTH_SECRET
• OMNIDESK_AUTH_ENDPOINT
• OMNIDESK_AUTH_EXPIRE

See: OmnideskAuth::Default

# app/controllers/support_controller.rb
class SupportController < ApplicationController
  def omnidesk_sign_in
    redirect_to OmnideskAuth.sso_auth_url(email: current_user.email)
  end
end

According to the documentation omnidesk service accepts as binding the following fields:

• iat (required) - Issued At (the time when the token was generated))
• email (required) - user email

Parameter "iat" is installed automatically during the generation of the token, but is also available for self-installation via the options hash. Parameter email is the only field that you need to be sure to pass.

Example of filling in all possible fields:

def omnidesk_sign_in
  redirect_to OmnideskAuth.sso_auth_url(
    iat: Time.current.to_i,
    name: current_user.name,
    email: current_user.email,
    external_id: current_user.id,
    company_name: current_user.company.name,
    company_position: current_user.position,
    remote_photo_url: current_user.avatar_url,
    exp: 1.day)
end
