Infrastructure/Authentication

OpenID Connect Authentication

Fedora Infrastructure is using OpenID Connect authentication, and this page is used to document the implementation details.

For development purposes, there is https://iddev.fedorainfracloud.org/. For staging and production client secrets please file an Infrastructure ticket.

Terminology

Some basic terminology required to read this page:

• OpenID Provider (OP)/ the Ipsilon deployment, this is the part that does user authentication and issues tokens
• Identity Provider (IdP): see OpenID Provider
• Relying Party (RP): any application that runs the OpenID Connect protocol.
• Resource Server: any application that accepts tokens issued by the OpenID Provider.
• UserInfo: TBD
• ID Token: TBD

Endpoint URLs

• Configuration URL for dynamic configuration: https://id.fedoraproject.org/openidc/.well-known/openid-configuration
• Authorization Endpoint: https://id.fedoraproject.org/openidc/Authorization
• Token Endpoint: https://id.fedoraproject.org/openidc/Token
• UserInfo Endpoint: https://id.fedoraproject.org/openidc/UserInfo
• Token Introspection URL: https://id.fedoraproject.org/openidc/TokenInfo

Suggested implementations

For Flask, the suggested client is Flask-OIDC, for both clients and resource servers. For other clients, no clients have been suggested at this point, please get in touch if you have suggestions.

Custom UserInfo fields

Field	Summary	Scope required
groups	List of groups the user is a member of	groups
cla	List of CLA URIs the user hs signed	cla

Scopes

In the Fedora Infrastructure, various applications are defined that specify various possible token scopes. These scopes are recorded here.

Every service will first list it's base namespace, and then the scope ID and a short summary of the scopes. To get the full scope to request, append the scope ID to the base namespace. So for example, to get the group information, this becomes: https://id.fedoraproject.org/scope/groups

The "Availability" line indicates whether this scope is live on the development, staging and production identity provider. A scope might not have progressed further because the application implementing it is only in a certain stage of development. This should only be edited by the infrastructure member that progresses the scope out further.

Registering new scopes

To register a new set of scopes, please feel free to just create a new section and then file a ticket on https://pagure.io/fedora-infrastructure/ to get them added to the development instance.

Also, once the scopes are finalized, please open a second ticket on https://pagure.io/fedora-infrastructure/ to request the scopes be added to the staging/production systems.

To add new scopes to an existing project, add a second table with the new scopes to the relevant section, follow the above process, and then merge the two tables back into one after the scopes are fully deployed.

Standard

These scopes are standardized, and not namespaced.

Availability: Development, Staging, Production.

Scope ID	Claims provided
openid	- This one is *required* for OpenID Connect requests
profile	name, nickname, preferred_nickname, profile, zoneinfo, locale, updated_at
email	email

Ipsilon

Base namespace: https://id.fedoraproject.org/scope/

Availability: Development, Staging, Production.

Scope ID	Summary
groups	Provides the "groups" attribute in the User Info.
cla	Providees the "cla" attribute in the User Info.

release-monitoring.org

Base namespace: https://release-monitoring.org/oidc/

Note: release-monitoring.org is used here in the sense of "the upstream project that maintains the Anitya software", and hence these scope names are used regardless of where any given Anitya instance is deployed

Availability: Development

Scope ID	Summary
upstream	Permission to register new upstream projects for monitoring
downstream	Permission to register new distros and new upstream/downstream mappings
