Customer Managed Applies to customer-managed instances of Alation


Alation Cloud Service customers can request server configuration changes through Alation Support.

Enter the Alation shell:

sudo /etc/init.d/alation shell

Change the alation_conf alation.db_authentication.credential_days_to_live parameter to the desired value, which is the number of days after which you want the credentials to expire. The default value is minus one (-1), which turns the feature off.


For keytab files, there is no automated cleanup; such cleanup would be the purview of server administrators at customer sites.
