Under some network configurations PAM (Pluggable Authentication Modules) will fail to lock access to disabled NIS accounts.

2. Problem description:
The PAM packages shipped with Red Hat Linux 6.1/Intel may allow access to locked NIS accounts on certain network configurations. If you have a Red Hat Linux 6.1 workstation performing authentication against a NIS server then you are at risk.

Previous versions of Red Hat Linux are not affected by this problem.
