## Tested Versions
* [Authelia]
* [v4.35.5](https://github.com/authelia/authelia/releases/tag/v4.35.5)
* [GitLab] CE
* 14.0.1
## Before You Begin
You are required to utilize a unique client id and a unique and random client secret for all [OpenID Connect] relying
parties. You should not use the client secret in this example, you should randomly generate one yourself. You may also
choose to utilize a different client id, it's completely up to you.
This example makes the following assumptions:
* __Application Root URL:__ `https://gitlab.example.com`
* __Authelia Root URL:__ `https://auth.example.com`
* __Client ID:__ `gitlab`
* __Client Secret:__ `gitlab_client_secret`
## Configuration
### Application
To configure [GitLab] to utilize Authelia as an [OpenID Connect] Provider:
1. Add the Omnibus [OpenID Connect] OmniAuth configuration to `gitlab.rb`:
```ruby
gitlab_rails['omniauth_providers'] = [
{
name: "openid_connect",
label: "Authelia",
icon: "https://avatars.githubusercontent.com/u/59122411?s=280&v=4",
args: {
name: "openid_connect",
scope: ["openid","profile","email","groups"],
response_type: "code",
issuer: "https://auth.example.com",
discovery: true,
client_auth_method: "query",
uid_field: "preferred_username",
send_scope_to_token_endpoint: "false",
client_options: {
identifier: "gitlab",
secret: "gitlab_client_secret",
redirect_uri: "https://gitlab.example.com/users/auth/openid_connect/callback"
}
}
}
]
```
### Authelia
The following YAML configuration is an example __Authelia__
[client configuration](../../../configuration/identity-providers/open-id-connect.md#clients) for use with [GitLab]
which will operate with the above example:
```yaml
- id: gitlab
secret: gitlab_client_secret
public: false
authorization_policy: two_factor
scopes:
- openid
- profile
- groups
- email
redirect_uris:
- https://gitlab.example.com/users/auth/openid_connect/callback
userinfo_signing_algorithm: none
```
