A clean upgrade, with the same privatedir would have worked fine.  If
you had smbpasswd in /etc/samba/private before (and therefore
secrets.tdb in /etc/samba/private as well) and you upgrade to 3.0 with
the private dir being /usr/local/samba/private, things like this will
break.  Basicly, make sure you put the files in their new locations
*before* you start Samba.

As to your problems, this is due to the SID having changed, which
changes the effect of ACLs in the registry.  The 'profiles' too in
Samba 3.0 might help.
