radcheck problem

[YvesDM <ydmlog@gmail.com>]

Hi,

I want a specific user (call him john) NOT to be able to login through a specific nas.
So I thought, just add this to radcheck

INSERT INTO `radcheck` (`UserName`, `Attribute`, `op`, `Value`) VALUES ('john','NASIdentifier','!=','nas-id')

(nas-id is the nasidentifier of the specific nas)

Anyway, when I add this entry to radcheck, john gets rejected all the time, no matter what nas he's connecting to.
Am I overlooking something? 


Kind regards
