Backup Samba config on RHEL4

[jared davis.]

I've been having a problem with winbind that is supposedly solved in the
newer versions of Samba, however the RHEL4 repository only has an old
version.  

Therefore, I need to uninstall the current Samba RPMs in order to
compile/install the new source file.  How do I back up my Samba config
files in order to make the transition smoothly?  I've already backed
up /etc/samba.

Thanks
