[CentOS] Where can I get samba-vscan from?

Hi there!

Am using CentOS 4.4. Have installed Samba and ClamAV. My understanding
is that there's a vfs module (samba-vscan) which I have to install for
Samba to virus scan its shares. Where can I get it from? I tried stuff
like "yum install samba-vscan" etc but it doesn't seem to be there in
the repos. I have RPMForge and the usual CentOS repos enabled.

Is this something I have to install from the sources or can I get a
binary package from someplace?

Thanks,
Rakhesh
