32 bit PAM package for RHEL 6.5 x86_64, for use with McAfee Virus Scan Enterprise for Linux

McAfee Virus Scan Enterprise for Linux requires a 32 bit PAM library to be installed in order to use the web browser functions of McAfee.

I am running RHEL 6.5 kernel 2.6.32-431.el6.x86_64

What/where is the 32 bit PAM library that I need to download and install?

yum install pam.i686 gives no results (no package available).

Thanks in advance,

Mark
