Ambari is able to configure Kerberos in the cluster to work with an existing MIT KDC, or existing Active Directory installation. This section describes the steps necessary to prepare for this integration.
![[Note]](../common/images/admon/note.png) | Note |
|---|---|
If you do not have an existing KDC (MIT or Active Directory), Install a new MIT KDC . Please be aware that installing a KDC on a cluster host after installing the Kerberos client may overwrite the krb5.conf file generated by Ambari. |
