+# OmniAuth CAS Strategy [![Gem Version][version_badge]][version] [![Build Status][travis_status]][travis]
+
+This is a fork of [omniauth-cas3](https://github.com/tduehr/omniauth-cas3) to
+support:
+
+1. OmniAuth v1 and v2. OmniAuth v2 disables GET requests by default
+   and defaults to POST. GitLab already has patched v1 to use POST,
+   but other dependencies need to be updated:
+   https://gitlab.com/gitlab-org/gitlab/-/issues/30073.
+2. We may deprecate this library entirely in the future:
+   https://gitlab.com/gitlab-org/gitlab/-/issues/366212
+
+[version_badge]: https://badge.fury.io/rb/omniauth-cas3.png
+[version]: http://badge.fury.io/rb/omniauth-cas3
+[travis]: http://travis-ci.org/tduehr/omniauth-cas3
+[travis_status]: https://secure.travis-ci.org/dlindahl/omniauth-cas3.png
+[releases]: https://github.com/tduehr/omniauth-cas3/releases
+
+This is a OmniAuth 1.0 compatible port of the previously available
+[OmniAuth CAS strategy][old_omniauth_cas] that was bundled with OmniAuth 0.3. This strategy has also been updated for CAS protocol version 3.0 and patched to deal with namespace issues.
+
+* [View the documentation][document_up]
+* [Changelog][releases]
+
+## Installation
+
+Add this line to your application's Gemfile:
+
+    gem 'omniauth-cas3'
+
+And then execute:
+
+    $ bundle
+
+Or install it yourself as:
+
+    $ gem install omniauth-cas3
+
+## Usage
+
+Use like any other OmniAuth strategy:
+
+```ruby
+Rails.application.config.middleware.use OmniAuth::Builder do
+  provider :cas3, host: 'cas.yourdomain.com'
+end
+```
+
+### Configuration Options
+
+#### Required
+
+OmniAuth CAS requires at least one of the following two configuration options:
+
+  * `url` - Defines the URL of your CAS server (i.e. `http://example.org:8080`)
+  * `host` - Defines the host of your CAS server (i.e. `example.org`).
+
+#### Optional
+
+Other configuration options:
+
+  * `port` - The port to use for your configured CAS `host`. Optional if using `url`.
+  * `ssl` - TRUE to connect to your CAS server over SSL. Optional if using `url`.
+  * `service_validate_url` - The URL to use to validate a user. Defaults to `'/serviceValidate'`.
+  * `callback_url` - The URL custom URL path which CAS uses to call back to the service.  Defaults to `/users/auth/cas3/callback`.
+  * `logout_url` - The URL to use to logout a user. Defaults to `'/logout'`.
+  * `login_url` - Defines the URL used to prompt users for their login information. Defaults to `/login` If no `host` is configured, the host application's domain will be used.
+  * `uid_field` - The user data attribute to use as your user's unique identifier. Defaults to `'user'` (which usually contains the user's login name).
+  * `ca_path` - Optional when `ssl` is `true`. Sets path of a CA certification directory. See [Net::HTTP][net_http] for more details.
+  * `disable_ssl_verification` - Optional when `ssl` is true. Disables verification.
+  * `on_single_sign_out` - Optional. Callback used when a [CAS 3.1 Single Sign Out][sso]
+    request is received.
+  * `fetch_raw_info` - Optional. Callback used to return additional "raw" user
+    info from other sources.
+
+    ```ruby
+    provider :cas3,
+             fetch_raw_info: lambda { |strategy, options, ticket, user_info|
+               ExternalService.get(user_info[:user]).attributes
+            }
+    ```
+
+Configurable options for values returned by CAS:
+
+  * `uid_key` - The user ID data attribute to use as your user's unique identifier. Defaults to `'user'` (which usually contains the user's login name).
+  * `name_key` - The data attribute containing user first and last name.  Defaults to `'name'`.
+  * `email_key` - The data attribute containing user email address.  Defaults to `'email'`.
+  * `nickname_key` - The data attribute containing user's nickname.  Defaults to `'user'`.
+  * `first_name_key` - The data attribute containing user first name.  Defaults to `'first_name'`.
+  * `last_name_key` - The data attribute containing user last name.  Defaults to `'last_name'`.
+  * `location_key` - The data attribute containing user location/address.  Defaults to `'location'`.
+  * `image_key` - The data attribute containing user image/picture.  Defaults to `'image'`.
+  * `phone_key` - The data attribute containing user contact phone number.  Defaults to `'phone'`.
+
+## Migrating from OmniAuth 0.3
+
+Given the following OmniAuth 0.3 configuration:
+
+```ruby
+provider :CAS, cas_server: 'https://cas.example.com/cas/'
+```
+
+Your new settings should look similar to this:
+
+```ruby
+provider :cas3,
+         host:      'cas.example.com',
+         login_url: '/cas/login',
+  	     service_validate_url: '/cas/p3/serviceValidate'
+```
+
+If you encounter problems wih SSL certificates you may want to set the `ca_path` parameter or activate `disable_ssl_verification` (not recommended).
