Resolution

  • Create the secret with the correct key name.
  • In the below example, the reference to the key is users.htpasswd:
[user@host beta3]$ oc get secret v4-0-config-user-idp-0-file-data -o yaml
apiVersion: v1
data:
  users.htpasswd: dXNlcjE6JDJ5JDA1JGQ1d2kzRldrVlhUWmJIOXlUNFBzMmVweWhiZzB6R2hrcWxqVHBaTWNpeWJNMFYxcTZxT3dHCg==
kind: Secret
metadata:
  creationTimestamp: 2019-04-12T15:37:58Z
  name: v4-0-config-user-idp-0-file-data
  namespace: openshift-authentication
  • This secret is pulling the information from another secret created in openshift-config project
[user@host beta3]$ oc get secret  htpass-secret -o yaml -n openshift-config
apiVersion: v1
data:
  users.htpasswd: dXNlcjE6JDJ5JDA1JGQ1d2kzRldrVlhUWmJIOXlUNFBzMmVweWhiZzB6R2hrcWxqVHBaTWNpeWJNMFYxcTZxT3dHCg==
kind: Secret
metadata:
  creationTimestamp: 2019-04-12T15:37:58Z
  name: htpass-secret
  namespace: openshift-config
  resourceVersion: "61924"
  selfLink: /api/v1/namespaces/openshift-config/secrets/htpass-secret
  uid: f28a9d73-5d38-11e9-af8f-0e5563093fdc
type: Opaque
  resourceVersion: "61925"
  selfLink: /api/v1/namespaces/openshift-authentication/secrets/v4-0-config-user-idp-0-file-data
  uid: f28c155d-5d38-11e9-af8f-0e5563093fdc
type: Opaque
  • Delete and recreate the secret by specifying the correct key name:
[user@host beta3]$ oc delete secret htpass-secret -n openshift-config
secret "htpass-secret" deleted
[user@host beta3]$ oc create secret generic htpass-secret --from-file=htpasswd=users.htpasswd -n openshift-config
secret/htpass-secret created

Root Cause

  • The secret was generated with the wrong key name.

Diagnostic Steps

  • Check the output of below commands:
$ oc get secret -n openshift-config
$ oc get secret -n openshift-authentication
$ oc get secret <secretname> -o yaml
