I am trying to evaluate RadiusNT 2.2 using a SQL server as the
authentication database. When I run the radius from the command prompt
in debug mode I get

radius: Invalid Database or Computer Date

When I test the connectivity of the ODBC datasource, it works fine. Can
someone please help as to what this error means.
