[Samba] Best strategy to undo an update

[Andrew B. Young]

My http authentication through winbind has stopped working with a Fedora
Core 2 update of httpd and samba (and others),
  httpd-2.0.49-4 -> httpd-2.0.50-2.1  & samba-3.0.3-5 ->  samba-3.0.6-2.fc2
which I believe is caused by a winbind bug 
(http://us1.samba.org/samba/news/#comingsoon_3.0.7)

What is the best strategy to fix this?  I can think of two:
1)      rpm --erase all the samba-*-3.0.6-2.fc2 packages and
        rpm --install all the samba-*-3.0.3-5 packages

    I have never done this, but suppose it will work.

2)  download the Samba 3.0.6 source, apply the patch, compile, install, 
& run

    I am worried this will somehow interfer w/ samba-*-3.0.6-2.fc2 packages
    preventing me from using the Fedora update in the future.

Thanks,
Andrw
