I like it, will check it out! Thanks for the review 🙏 |
But how to do that, in combination with the Symfony Cache callbacks? They have their own cache, so they could also be evicted separately etc. |

There was a problem hiding this comment.
Do we want to keep synchronous HTTP calls? Shouldn't we do concurrent ones?

Let's have a single cache entry. I don't see the need for many 🤷

When a firewall accepts tokens from multiple identity providers, it needs to validate tokens against different OIDC discovery endpoints. This change allows configuring multiple named discovery servers instead of just one, while keeping backward compatibility.

When a firewall accepts tokens from multiple identity providers, it needs to validate tokens against different OIDC discovery endpoints. This change allows configuring multiple named discovery servers instead of just one, while keeping backward compatibility.
With this change, we allow configuring multiple discovery endpoints with different (or the same) cache storage. They all use a different cache key.
It then builds a JWTSet of all the keys fetched, from the multiple endpoints, and then validates the JWT against that total JWTSet.
/cc @vincentchalamon @Jean-Beru @chalasr @Spomky Tagging you as you were all involved in previous OIDC PR's. Curious to hear your opinions about this 🙏
