[CentOS] How to Disable PAM in Centos 5.1

Hello all

I would like to disable PAM authentication in my test server running Centos5.1.

Currently I get an error that states:

"Feb 22 02:01:31 localhost login: pam_securetty(login:auth): access
denied: tty 'tty1' is not secure !"

I would like to DISABLE the PAM authentication; am unable to get the
answer after googl'ing for hours; if anyone is familiar on how to do
this: please advise.  I am quite new to the intricacies of this OS;
please bear the naive questions.
