I think it's safe to say the Ironic community would be very invested in such an effort. Let's make sure the time chosen for vPTG with this is such that Ironic contributors can attend as well.

Thanks,

Hello Everyone,

Recently, Tacker and Keystone have been working together on a new Keystone Middleware that can work with external authentication
services, such as Keycloak. The code has already been submitted [1], but we want to make this middleware a generic plugin that works
with as many OpenStack services as possible. To that end, we would like to hear from other projects with similar use cases
(especially Ironic and Barbican, which run as standalone services). We will make a time slot to discuss this topic at the next vPTG.
Please contact me if you are interested and available to participate.
