RADDB 2.1.7 and /etc/shadow

Greetings,
I installed a fresh copy of FreeRadius v 2.1.7 on CentOS 5. Ran radtest
locally as well as remotely and it works great. Now I want to point
the server to my /etc/shadow file which lives on the same machine. I
have not made any changes to the default config except to change the
group ownership of my shadow file to radiusd so the radius daemon can
access it.
On startup here is the output:
[root at labprinter raddb]# radiusd -X

And yes, there is a user named support with a hashed password that
equals "test"
Although it looks like the unix module is being queried, it does not
look like the server is passing the request to the passwd module
The references in the default and inner-tunnel files to shadow are
meaningless as they refer to a section in radiusd.comf that does not exist.
Any assistance is appreciated.
