Based on a simple experiment, I don't think this is true (or I'm mis-understanding your explanation). What I did is log into a host that uses NFSv4 sec=krb5p home directories. klist shows the service ticket for nfs as not expiring until October 27, 2016 (I have all ticket lifetimes in Kerberos configured for 70 days). Now, I do a "kdestroy" and make a note of the time. I then run a simple loop like this: # while [ 1 ] ; do date ; ls ; sleep 1m ; done Twice now I've done this experiment on two different hosts. After almost exactly an hour, I start getting "Permission denied". But from your description above, I would expect that I shouldn't see "Permission denied" until the end of October, right? -- To unsubscribe from this list: send the line "unsubscribe linux-nfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
