Kerberos Ticket renewal when in sleep mode with Active Directory integration

Hi,

I experience the following troubles: My Mac is integrated into an Active Directory.

I let the computer sleep overnight putting the Logon window on (I do not log out, I just activate the Logon Window!). Every time I come back to work, my Kerberos Tickets expired. They will not auto-renew when I log in through the logon window (but they will when I logout and re-logon).

I then experience quite slow access to SMB Network Volumes, etc. until I manually renew the Tickets via kinit.
