             Summary: Kerberos: during disable, need option skip if unable to access KDC to remove principals
                 Key: AMBARI-10305
                 URL: https://issues.apache.org/jira/browse/AMBARI-10305
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.0.0
            Reporter: Robert Levas
            Assignee: Robert Levas
            Priority: Critical
             Fix For: 2.1.0


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*
Add a flag to the kerberos-env configuration to specify whether Kerberos identities should be managed by Ambari (true, default) or not (false).  This flag is to be overridable via a _directive_ like {{manage_identities=false}} when disabling Kerberos, which will skip over any KDC administrative processes.
