Group Authentication

[Mike Wilson]

I have compiled FreeRADIUS 2.1.8 on a fresh Ubuntu 9.10 install.  I am using
Microsoft SQL Server as a backend.  I have installed and successfully
configured UnixODBC and FreeTDS to get FreeRADIUS to communicate with the
server.  FreeRADIUS will authenticate users correctly from the radcheck and
radreply tables.  However, I am also trying to get it to return attributes
based on their group assignment.  I have uncommented the 'read_groups = yes'
directive and also put a 'Fall-Through = yes' into the radreply table, and
FreeRADIUS still will not check the group assignments.  I am at a loss here
as I have tried to get this working for almost a week now.  Any help would
be greatly appreciated!  Below is the output of my radiusd -X.

FreeRADIUS Version 2.1.8, for host i686-pc-linux-gnu, built on Mar 19 2010
