My client has a Keycloak setup from a previous developer, and we are having some trouble setting up a token exchange to work with new Facebook compliance standards for iOS login. I've asked one of the mods of this mailing list if I can send an email for anyone who might be interested in working on this - most of the work should be done (I think), it should mostly be a matter of correctly setting client policies. If you're interested feel free to contact me with an idea of what you think this will cost.
