What are the major open source alternatives to Auth0?


I'm trying to get more familiar with the options that exist for open source auth providers that provide similar service to Auth0 or Google Accounts (so, more focused on OIDC than older protocols like LDAP). I'm aware of Keycloak, Kanidm, SuperTokens, Ory, FusionAuth.

Are there any other open source auth providers I should look into?

Also, floating around out there, somewhere, on the 'net, should be whatever became of the old Sun Identity Manager product. During the Jonathon Schwartz era, Sun made a TON of their products Open Source, but after the Oracle acquisition a lot of that stuff was left to more or less die on the vine. But in some cases, other firms picked up the code and continued the project(s). I think that happened for their Idm product, but don't quote me on that.
