Summary: check_radius doesn't detect or report authentication errors

Initial Comment:
The check_radius plugin exits with status 0 and no messages if it gets a "result" it isn't expecting. This issue is tickled when you use an incorrect password. In that case, radiusclient returns REJECT_RC (2).

The attached patch (against 1.4.13) adds a case to handle REJECT_RC and also complains if an unexpected result is returned.

Although I did not actually test the snapshot version, examination of the code indicates that 1.4.14-61-g45e2 still has these issues.

Message:
I'm using radiusclient-ng 0.5.6 (which although is a few years old also
appears to be the current release) on a FreeBSD 7.2-RELEASE system. I build
radiusclient-ng and nagios-plugins using ports.

% find . -name '*.[ch]' | xargs egrep REJECT_RC
./radiusclient-ng-0.5.6/include/radiusclient-ng.h:#define REJECT_RC     2
./radiusclient-ng-0.5.6/lib/sendserver.c:               result =
REJECT_RC;

Message:
Which library/version are you using for radius? We currently support the
original radiusclient and radiusclient-ng, and none of them provide the
REJECT_RC macro. 

I'll apply the last hunk anyway, but for the rest i'd like to know where
it's from at the very least.

Thanks
