# CAS OmniAuth Provider
|
|
|
|
To enable the CAS OmniAuth provider you must register your application with your CAS instance. This requires the service URL GitLab will supply to CAS. It should be something like: `https://gitlab.example.com:443/users/auth/cas3/callback?url`. By default handling for SLO is enabled, you only need to configure CAS for backchannel logout.
|
|
|
|
1. On your GitLab server, open the configuration file.
|
|
|
|
For omnibus package:
|
|
|
|
```sh
|
|
sudo editor /etc/gitlab/gitlab.rb
|
|
```
|
|
|
|
For installations from source:
|
|
|
|
```sh
|
|
cd /home/git/gitlab
|
|
|
|
sudo -u git -H editor config/gitlab.yml
|
|
```
|
|
|
|
1. See [Initial OmniAuth Configuration](omniauth.md#initial-omniauth-configuration) for initial settings.
|
|
|
|
1. Add the provider configuration:
|
|
|
|
For omnibus package:
|
|
|
|
```ruby
|
|
gitlab_rails['omniauth_providers'] = [
|
|
{
|
|
"name"=> "cas3",
|
|
"label"=> "cas",
|
|
"args"=> {
|
|
"url"=> 'CAS_SERVER',
|
|
"login_url"=> '/CAS_PATH/login',
|
|
"service_validate_url"=> '/CAS_PATH/p3/serviceValidate',
|
|
"logout_url"=> '/CAS_PATH/logout'
|
|
}
|
|
}
|
|
]
|
|
```
|
|
|
|
|
|
For installations from source:
|
|
|
|
```
|
|
- { name: 'cas3',
|
|
label: 'cas',
|
|
args: {
|
|
url: 'CAS_SERVER',
|
|
login_url: '/CAS_PATH/login',
|
|
service_validate_url: '/CAS_PATH/p3/serviceValidate',
|
|
logout_url: '/CAS_PATH/logout'} }
|
|
```
|
|
|
|
1. Change 'CAS_PATH' to the root of your CAS instance (ie. `cas`).
|
|
|
|
1. If your CAS instance does not use default TGC lifetimes, update the `cas3.session_duration` to at least the current TGC maximum lifetime. To explicitly disable SLO, regardless of CAS settings, set this to 0.
|
|
|
|
1. Save the configuration file.
|
|
|
|
1. Run `gitlab-ctl reconfigure` for the omnibus package.
|
|
|
|
1. Restart GitLab for the changes to take effect.
|
|
|
|
On the sign in page there should now be a CAS tab in the sign in form.
