The 3.5 is a problem in the older 3.5 code base. The fact it doesn't
work with 3.6 (based on what I have read, but not yet tried, sorry
Andrew Bartlett... I haven't yet had the time to get F16 Alpha installed
to play around since the install disks don't work for me) is likely due
to some improper setup of your DNS and the Kerberos/S4 side.

Or, on second read, it sounds like Samba 3.[56] isn't doing the deletes
on failure that Windows does.
