Description Avinash Hanwate 2023-11-02 04:06:24 UTC 
Windows Machine Config Operator approves CSRs for all nodes trying to join a cluster with WMCO installed. This fails here:
https://github.com/openshift/windows-machine-config-operator/blob/fbe9551005ca0f192c5cbc57e7ab781313dfc827/pkg/csr/csr.go#L84
validateCSRContents can return false without setting an error. This was introduced in
https://github.com/openshift/windows-machine-config-operator/commit/2a00c3129f810cc840b1fd2adcf3e7c6bf303ac9
before this commit, only !valid was checked.
