Dear all,

I am running Samba4 with a couple of Windows XP computers.

I started to watch at the windows event log and I see quite often this message

The kerberos subsystem encountered a PAC verification failure.  This indicates that the PAC from the client mycomputer$ 
in realm TESTAD.TST had a PAC which failed to verify or was modified.  Contact your system administrator.

I did some search on internet and find this
Everything is ok except for the KDC service but I think it's quite logic due to the fact that XP should not act as a 
kerberos Key Distribution Center (to my mind).

I am wondering if it's related to samba4 or not at all.
