Question on renewable lifetime

[miguel.sanders@arcelormittal.com]

Hi

I'm having a background process which requires a service principal to
work correctly.
Currently, I'm having a cron job which does a kinit (with the keytab
supplied) for that service principal.
Wouldn't it be better to renew the ticket instead of doing the above?
As a result, I would have to set the renewable lifetime for that service
principal to unlimited. 

What is your idea on this? What is the best way?
