OpenID Connect service configuration¶
Go in Manager and click on
OpenID Connect Service node.
Set the issuer identifier, which should be the portal URL.
For example: http://auth.example.com
Name of different OpenID Connect endpoints. You can keep the default values unless you have a specific need to change them.
- User Info
- End of session
- Check Session
The end points are published inside JSON metadata.
You can associate here an authentication context to an authentication level.
- Keys : define public/private key pair to do asymmetric signature
- Signing Key ID: ID of signing key
- Dynamic Registration: Set to 1 to allow clients to register themselves. This may be a security risk as this will create a new configuration in the backend per registration request. You can limit this by protecting in the WebServer the registration end point with an authentication module, and give the credentials to clients.
- Authorization Code flow: Set to 1 to allow Authorization Code flow
- Implicit flow: Set to 1 to allow Implicit flow
- Hybrid flow: Set to 1 to allow Hybrid flow
It is recommended to use a separate sessions storage for OpenID Connect sessions, else they will stored in the main sessions storage.
If dynamic registration is enabled, you can configure the following
options to define attributes and extra claims when a new relying party
is registered trough the
- Exported vars for dynamic registration
- Extra claims for dynamic registration
Key rotation script¶
OpenID Connect specification let the possibility to rotate keys to improve security. LL::NG provide a script to do this, that should be put in a cronjob.
The script is
/usr/share/lemonldap-ng/bin/rotateOidcKeys. It can be
run for example each week:
5 5 * * 6 www-data /usr/share/lemonldap-ng/bin/rotateOidcKeys
Set the correct Apache user, else generated configuration will not be readable by LL::NG.
LL::NG implements the OpenID Connect Chance Notification specification
changed state will be sent if the user is disconnected from LL::NG
portal (or has destroyed its SSO cookie). Else the

To work, the LL::NG cookie must not be protected against
