Description

Attempted to disable kerb, fails on step to unkerberize because KDC admin is locked out.

Click retry, can't make it past that.

Need option to skip and finish "disable kerberos" even if Ambari cannot get the principals cleaned up (i.e. cannot access the KDC) Losing access to the KDC and attempting to disable where ambari can't clean-up the principals should be a skip'able step. User should still be able to get to a clean, not-enabled-kerberos-ambari-state w/o accessing the KDC.

Solution
Based on user input, execute API call to disable Kerberos with the manage_kerberos_identities directive set to false. Example:

PUT /api/v1/clusters/c1?manage_kerberos_identities=false

{
  "Clusters": {
    "security_type" : "NONE"
  }
}
