Important Reading
This section contains important elements that you should carefully consider before configuration of an OpenID Connect 1.0 Registered Client.
Common Notes
- The OpenID Connect 1.0
client_id
parameter:- This must be a unique value for every client.
- The value used in this guide is merely for readability and demonstration purposes and you should not use this value in production and should instead utilize the How do I generate a client identifier or client secret? FAQ. We recommend 64 random characters but you can use any arbitrary value that meets the other criteria.
- This must only contain RFC3986 Unreserved Characters.
- This must be no more than 100 characters in length.
- The OpenID Connect 1.0
client_secret
parameter:- The value used in this guide is merely for demonstration purposes and you should absolutely not use this value in production and should instead utilize the How do I generate a client identifier or client secret? FAQ.
- This string may be stored as plaintext in the Authelia configuration but this behaviour is deprecated and is not guaranteed to be supported in the future. See the Plaintext guide for more information.
- When the secret is stored in hashed form in the Authelia configuration (heavily recommended), the cost of hashing can, if too great, cause timeouts for clients. See the Tuning the work factors guide for more information.
- The configuration example for Authelia:
- Only contains an example configuration for the client registration and you MUST also configure the required elements from the OpenID Connect 1.0 Provider Configuration guide.
- Only contains a small portion of all of the available options for a registered client and users may wish to configure portions that are not part of this guide or configure them differently, as such it’s important to both familiarize yourself with the other options available and the effect of each of the options configured in this section by looking at the OpenID Connect 1.0 Clients Configuration guide.
Assumptions
This example makes the following assumptions:
- Application Root URL:
https://minio.example.com/
- Authelia Root URL:
https://auth.example.com/
- Client ID:
minio
- Client Secret:
insecure_secret
Some of the values presented in this guide can automatically be replaced with documentation variables.
Configuration
Authelia
Additional Configuration Required: Claims Conformance
For the reasons noted below; in addition to the configuration example you will likely have to configure a claims policy and assign that policy to the client in order to get the expected claims into the ID Token which is described and documented here.
Authelia has adopted a claims architecture that is conformant with the specification. This expects the clients to act inline with the OpenID Connect 1.0 specification and either obtain user information from the user information endpoint or explicitly request them via the claims parameter.
At the time of this writing this client did not support this, and very likely also ignores the
claims stability warning
which requires clients to anchor accounts via the sub
and iss
claims. Both of these
elements are clear indications the client does not properly support
OpenID Connect 1.0 and is not conformant.
The following YAML configuration is an example Authelia client configuration for use with MinIO which will operate with the application example:
identity_providers:
oidc:

Application
To configure MinIO to utilize Authelia as an OpenID Connect 1.0 Provider you can either use the GUI or environment variables.
You may also want to consider adding a default policy to your user groups in Authelia.
GUI
- Login to MinIO
- On the left hand menu, go to
Identity
, thenOpenID
- On the top right, click
Create Configuration
- On the screen that appears, enter the following information:
- Name:
authelia
- Config URL:
https://auth.example.com/.well-known/openid-configuration
- Client ID:
minio
- Client Secret:
insecure_secret
- Claim Name:
groups
- Display Name:
Authelia
- Claim Prefix: Leave Empty
- Scopes:
openid,profile,email,groups
- Redirect URI:
https://minio.example.com/oauth_callback

- Redirect URI Dynamic: Disabled
- Name:
- Press
Save
at the bottom - Accept the offer of a server restart at the top
- Refresh the page and sign out if not done so automatically
- Add your user to an authelia group that matches the policy name in MinIO. There are select default policies that can be used. (The group name and policy name must match.)
- When the login screen appears again, click the
Other Authentication Methods
open, then selectAuthelia
from the list. - Login
