Strange problem with ticket renewal

Sorry.
Here's the deal: you must get all the little ducks in a row.
Specifically, the renewable life is set to be the minimum of:
- the requested renewable life
- the client principal's max renewable life
- the service principal's max renewable life
- the max renewable life for the realm (or one day, if not set)
The principals' max renewable life times are set in the KDB records with
kadmin. By default new principals get a max renewable life of 0 if the
max renewable life for the realm is not set in kdc.conf. The kdb5_util
utility sets the max renewable life for the TGS the same way.
So, chances are that your krbtgt/<realm>@<realm> has a max renewable
life time of 0. Fix that, and your users' max renew times and you'll be
set.
As to why the MIT kdc issues tickets with renewal expiration set for one
day ago when the renewable lifetime calculated as above comes to 0, I
don't know. But once you fix the TGS and what not it all works.
Cheers,
Nico
