cisco 3825 authentication error

[Dom]

I am trying to terminate vpdn sessions through our cisco 3825 using 
freeradius.  I am new to this whole process and I was hoping to get some 
assistance with the missing configuration.

Below is the error message I am receiving when trying to authenticate 
via the router.
