[Serusers] SER and Radiusclient-ng on 64bit Linux OS

I've compiled and installed the sources successfully on a Sun Mircosystems 20z with Red Hat Enterprise v3 running the OS. When I try to use radius it always fails to log the user in and authenticate with radius. If I run SER on a 32 bit system with the same configurations as the 64 bit system it works fine. After reading some documentation, I caught reference in regards to radiusclient-ng only supported on 32 bit systems. Is this true? The only thing that doesn't work is when a user tries to authenticate through radius the authentication always fails on the 64 bit OS. Am I missing any pre-configuration options prior to compiling on a 64 bit OS? Please help. ~Alan Error message received from debug: pre_auth(): Credentials with given realm not found
