Kerberized NFSv3 client for Linux

[sureshjayaram@gmail.com]

A brief on my setup
KDC Server: RedHat Linux
NFS Server: Kerberized Solaris NFS Server (v3)

I want to setup NFSv3 client for Linux. I know Kerberized NFSv4 client
is available here http://www.citi.umich.edu/projects/nfsv4/linux/

Please let me know whether Kerberized NFSv3 client for Linux is
available or not; if available, any pointers to setup the client. Can I
use kerberized NFSv4 client ?

Thanks for your time
Suresh
