Hi again,
I've figured out that it has nothing to do with leaving the session on over
night. I changed the ticket life to 10 minutes, and even if i have a new key i
am denied access once the original one expires...
Any help would be great!
Thomas

Subject: Key has expired - NFS + krb5 + autofs + sssd
Hi,
I mount a NFS share (windows file server) with autofs and sssd on my ubuntu
16.04 server that I connect to via ssh. Where I run into a problem is when i
leave my ssh session on over night and come back in the morning I get a "key
has expired" error when I try and access it. The only thing that fixes it is
if, i close my ssh session and create a new one. I have tried using krenew
(or the built in sssd ticket renewel) but it doesn't fix the problem. I even
wrote a simple script that creates a new ticket every hour i.e. :
kinit ${user} -kt /usr/krb5/keytabs/.${user}.keytab
and it does in fact generate a new ticket every hour. This morning I did a
klist, I saw that I had a new valid ticket but still couldn't access the NFS
share this morning.
Any ideas or suggestions in debuging this would be a great help since I have
spent days trying to find a solution.
Thanks!
Thomas
