This works for me.

I have this in "/etc/auto.cifs"

Share -fstype=cifs,multiuser,cruid=${UID},sec=krb5 ://server/Share


and this in "/etc/auto.master"

/cifs /etc/auto.cifs --timeout=300 --ghost


This ways if the share is not used it is unmounted and mounted again 
when the folder is opened.

But my Kerberos ticket is renewed automatically.

By the was which SPNs did you create? I did not have to do this.
