ruby - How pass oAuth2 server URL in config/gitlab.yml under providers -

we have setup gitlab , working well. have our own oauth2 server we'd connect to, account in our oauth2 server can have access gitlab.

we've installed omniauth-oauth2 (https://rubygems.org/gems/omniauth-oauth2) , have enabled in gitlab.yml this:

omniauth: enabled: true providers: - { name: 'oauth2' }

when restart gitlab see oauth2 button on login page, url our oauth2 server wrong, , haven't set out app_id , app_secret.

my question is: how pass params , related data app_id, app_secret , oauth2 server url via settings file. we've tried number of things far, haven't gotten far.

notes:

• i've never used ruby before week. learned lot far!
• we've attempted set additional args args: { url: 'url-to-our-oauth2-server' }
• i believe need create own strategy file, plan on doing based on supplied omniauth-oauth2 strategy file

to use our own oauth server, had write our own strategy implements omniauth, , import via gemfile. oauth urls within strategy. placed our oauth keys in /home/git/gitlab/config/initializers/devices.rb file before last 'end' statement:

    end     config.omniauth :strategy_name, "{client_id_goes_here}", "{client_key_goes_here}" end 

our strategy looks this, replacing strategy_name strategy name, , replacing site, authorize_url , token_url own urls:

require 'omniauth-oauth2'  module omniauth   module strategies     class strategy_name < omniauth::strategies::oauth2    option :client_options, {     :site => 'https://authserve.mydomain.com',     :authorize_url => 'https://authserve.mydomain.com/oauth/authorize',     :token_url => '/oauth/access_token'   }    def request_phase     super   end    def authorize_params     super.tap |params|       %w[scope client_options].each |v|         if request.params[v]           params[v.to_sym] = request.params[v]         end       end     end   end    uid { raw_info['id'].to_s }    info     {       :email => raw_info['email'],       :name => raw_info['name'],       :nickname => raw_info['username']     }   end        {:raw_info => raw_info}   end    def raw_info     @raw_info ||= access_token.get("/v1/users?access_token=#{access_token.token}").parsed   end  end   end end
