[Help-gnu-radius] Extending authentication with GNU RADIUS

[David Beards]

Hi Everyone,

I'd like to extend the authentication of GNU RADIUS to not only exclude 
Simultaneous users, but also allow for the checking and recording of 
failed attempts at connecting.

i.e. When authentication is performed, part of the process is to check 
to see if the correct username password is provided. If it is not, a 
counter in a file is incremented until such time as the user has a 
predetermined number of failures. Once the predetermined number of 
failures has been reached they are automatically denied access to the 
NAS until the users entry is manually removed. If a successful 
connection is achieved prior to being locked out, the users login 
attempts are zeroed and the process occurs all over again. (Basically 
similar to the way that Windows NT/2000/XP locks its users out.)

If anyone has any suggestions as to how this might be achieved I'd be 
very appreciative.
