Thanks, I'll put this in the README for the next version.

On an FC2 test server running samba-3.0.7-2.FC2 and
with idmap_ad, if I start winbind "normally" idmap_ad
fails, but if I first kinit the machine account,
idmap_ad works fine.

Without idmap_ad in smb.conf, winbind is fine.

This problem appears not to occur with samba-3.0.5
(build from source tarball, running RedHat 8.0).  I
will try with samba-3.0.7-1 from samba.org on FC2 as I
get a chance, but I was wondering if anyone had any
clues as to what the problem may be.  I have attached
a little more infor in the postscript.

Thanks,
