I suspect this to be some admission webhook or something that API server is making requests to (oauth?)

Mo, any ideas?

(setting severity low to get this off the blocker list as this is likely just some misconfiguration and it is not breaking the cluster)

$ oc get user 'kube:admin'
The User "kube:admin" is invalid: metadata.name: Invalid value: "kube:admin": may not contain ":"
[hasha@fedora_pc ~]$ oc logs apiserver-bh9cn -n openshift-apiserver |grep "received an error"
[hasha@fedora_pc ~]$ 

$ oc get clusterversion
