nfsv4 sec=krb5 + xscreensaver

[FM]

Hello,

We are are using MIT krb5 + LDAP on server and pam_krb5
(pam_krb5-2.1.2-1) on clients

I'd like to use nfsv4 sec=krb5 for my home users folers.

with sec=krb5, the nfs server will check the TGT of the user, the prob is :
when you unlock you computer, yout TGT is not creat of renew.
So user nee to kinit again.

So , I suppose, that I won't be able to use my home folder after the TGT
expiration.


Is there a way to renew TGT when locking computer with xscreensaver ?
