kstart

Automated Kerberos ticket cache and keytab management utilities

k5start is a modified version of kinit that can use keytabs to authenticate, can run as a daemon and wake up periodically to refresh a ticket, and can run single commands with their own authentication credentials and refresh those credentials until the command exits. It is commonly used to maintain Kerberos tickets for services that need to authenticate to minimize the amount of Kerberos-related logic that must be in the service itself.
