#Keycloak question: is there a way to allow multiple service accounts/machines to use one OIDC client?

Normally we'd go one OIDC client in confidential mode with the service account using client credentials flow - per machine access.

However, each OIDC client/service account means a new OIDC audience - and AWS has a hard limit of 100.

Direct Access grant flow is deprecated already and removed entirely I think from Oauth2.1 spec in strict mode.

Maybe we could just create users to represent the machines - but we'd have to find a way to exempt them from Realm policies like MFA etc and it still feels icky.
