Invalid character value for cast specification

I'm trying to test Radius 2.5 and my server will not authenticate users.
It can't find them after the select to query to see if it's in the
subaccount table, there is an error that is returned:

ODBC Error:22005:0: Invalid character value for cast specification.

Any ideas on this?
