[CentOS] CentOS 6.2 Autofs stopped working

Seems that autofs in 6.2 stopped working like it used to.

We use NIS and automount maps.

Primary map  auto.sf
ssdt            -fstype=autofs,rw   auto_ssdt

auto.ssdt map
scratch    -fstype=nfs,hard,intr gold:/vol/ssdt/scratch

So finding a path  such as /sf/ssdt/scratch has always worked and continues to work on non CentOS 6.2 machines.
This ability stopped with CentOS 6.2

CentOS 6.0  uses
autofs-5.0.5-23.el6.x86_64.rpm

CentOS 6.2 uses
autofs-5.0.5-39.el6.x86_64.rpm

The work around seems to be to remove autofs in CentOS 6.2
And do an rpm install of autofs from CentOS 6.0.

I presume it is a flaw upstream.
Anyone else observing this behavior?
