> When generating accounts in an Active Directory, it may be useful to add a unique value to CN's.  In the past generating this value was done by taking the SHA1 hash of the relevant normalized principal name. For example {{ambari-qa-c1@EXAMPLE.COM}} yields {{d9b48cb1c075d3da9fab4855a4031266bab8fb6a}}.  
> Because using SHA1 at all may not be desirable, Ambari should provide options to use the following digest algorithms in the Active Directory account creation attribute template ({{kerberos-env/ad_create_attributes_template}}:
> ||Attribute Variables||Example||
> |$principal_digest|SHA1 hash of the $normalized_principal|
> |$principal_digest_256|SHA256 hash of the $normalized_principal|
> |$principal_digest_512|SHA512 hash of the $normalized_principal|
>
