## 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
|
|
|
|
|
```
|
|
