Need help deploying kubernetes with always allow as authorization mode

Cluster information:

Kubernetes version: 1.18
Cloud being used: bare-metal
Installation method: I need info on how to deploy kubernetes with authorization mode as AlwaysAllow. But when i deploy using config file or change mode after deploying with default config from(Node,RBAC) to (AlwaysAllow), accessing api server https://myserver.domain.com:6443 shows 401 unauthorized and api server container keeps recreating after a minute. Please help me out, pointing what are the changes i need to do to achieve my expected configuration to work(like in api server config file, kubelet)
Host OS: Oracle Linux 7.x
CNI and version: 0.8.6
I am using docker 19.03.01.ol

I haven’t found much documentation on this other than setting the following on Kube-apiserver:

--authorization-mode=AlwaysAllow

Can you share details of exactly what you tried?
Also share ps -ef output of running kube-apiserver to confirm the flag is set correctly.

Are you setting this for testing purposes?
Most website seem to suggest against using it for anything other than testing.

Kind regards,
Stephen
