unable to authenticate okd against keycloak 21.1.1

[jas01]

I'm using OKD with keycloak authentication. It's was working until I upgrade keycloak to 21.1.1
Of course my first reflexe was «the problem are with keycloak», but I got many other application who authenticate perfectly with keycloak 21.1.1 (at least gitlab, discours, tulipchat, etc.)

Version

4.12.0-0.okd-2023-04-16-041331

How reproducible
The okd can authenticate with Keycloak 20.0.2, but not working with 21.1.1
It's 100% reproductible.

I eventually find out the problem, I write this comment in case someone got the same issue.

It come from the name of the object

kind: OAuth
metadata:
  labels:
    app.kubernetes.io/instance: openshift-config
  name: cluster
spec:
  identityProviders:
  - mappingMethod: claim
    name: OIDC_something

if the name containt a space (like OIDC something) it's not working anymore with keycloak 21.1.1 but without it's working well.
