From 04fef7b8886bb78f3473e143894a521ca578f1db Mon Sep 17 00:00:00 2001 From: Alexander Date: Fri, 2 Feb 2018 10:18:55 +0100 Subject: [PATCH] pam authentication (#5303) * add pam support, without extra column * bugfixes for pam login * document options * fix code style * fix codestyle * fix tests * don't call remember_me without password * fix codestyle * improve checks for pam usage (should fix tests) * fix remember_me part 1 * add remember_token column because :rememberable requires either a password or this column. * migrate db for remember_token * move pam_authentication to the right place, fix logic bug in edit.html.haml * fix tests * fix pam authentication, improve username lookup, add comment * valid? is sometimes not honored, return nil instead trying to authenticate with pam * update devise_pam_authenticatable2 and adjust code. Fixes sideeffects observed in tests * update devise_pam_authenticatable gem, fixes for codeconventions, fix finding user * codeconvention fixes * code convention fixes * fix idention * update dependency, explicit conflict check * fix disabled password updates if in pam mode * fix check password if password is present, fix templates * block registration if account is maintained by pam * Revert "block registration if account is maintained by pam" This reverts commit 8e7a083d650240b6fac414926744b4b90b435f20. * fix identation error introduced by rebase * block usernames maintained by pam * document pam settings better * fix code style --- Gemfile | 3 + Gemfile.lock | 5 ++ app/controllers/application_controller.rb | 5 ++ .../auth/registrations_controller.rb | 5 ++ app/controllers/auth/sessions_controller.rb | 6 +- app/models/user.rb | 69 +++++++++++++++++++ .../unreserved_username_validator.rb | 6 ++ app/views/auth/passwords/edit.html.haml | 18 +++-- app/views/auth/registrations/edit.html.haml | 15 ++-- app/views/auth/sessions/new.html.haml | 5 +- config/initializers/devise.rb | 34 ++++++++- config/locales/simple_form.de.yml | 1 + config/locales/simple_form.en.yml | 1 + ...80109143959_add_remember_token_to_users.rb | 5 ++ db/schema.rb | 3 +- 15 files changed, 164 insertions(+), 17 deletions(-) create mode 100644 db/migrate/20180109143959_add_remember_token_to_users.rb diff --git a/Gemfile b/Gemfile index eaa1d29de..f3844aca6 100644 --- a/Gemfile +++ b/Gemfile @@ -30,6 +30,9 @@ gem 'iso-639' gem 'cld3', '~> 3.2.0' gem 'devise', '~> 4.4' gem 'devise-two-factor', '~> 3.0' + +gem 'devise_pam_authenticatable2', '~> 8.0' + gem 'doorkeeper', '~> 4.2' gem 'fast_blank', '~> 1.0' gem 'goldfinger', '~> 2.1' diff --git a/Gemfile.lock b/Gemfile.lock index b3bd6fcb0..7da9bfe39 100644 --- a/Gemfile.lock +++ b/Gemfile.lock @@ -137,6 +137,9 @@ GEM devise (~> 4.0) railties (< 5.2) rotp (~> 2.0) + devise_pam_authenticatable2 (8.0.1) + devise (>= 4.0.0) + rpam2 (~> 3.0) diff-lcs (1.3) docile (1.1.5) domain_name (0.5.20170404) @@ -420,6 +423,7 @@ GEM actionpack (>= 4.2.0, < 5.3) railties (>= 4.2.0, < 5.3) rotp (2.1.2) + rpam2 (3.1.0) rqrcode (0.10.1) chunky_png (~> 1.0) rspec-core (3.7.0) @@ -570,6 +574,7 @@ DEPENDENCIES climate_control (~> 0.2) devise (~> 4.4) devise-two-factor (~> 3.0) + devise_pam_authenticatable2 (~> 8.0) doorkeeper (~> 4.2) dotenv-rails (~> 2.2) fabrication (~> 2.18) diff --git a/app/controllers/application_controller.rb b/app/controllers/application_controller.rb index e1aae0b67..b38a68467 100644 --- a/app/controllers/application_controller.rb +++ b/app/controllers/application_controller.rb @@ -14,6 +14,7 @@ class ApplicationController < ActionController::Base helper_method :current_session helper_method :current_theme helper_method :single_user_mode?
