Fabio,

The threshold throttle is a rate. In your example it works out to 1 failed 
attempt in 100 seconds. Any user will try a second time within that 100 
seconds. Set the numbers to a reasonable user action time - how long does it 
take for a user to type and press enter, maybe 5 seconds. Set threshold at 1 
and range at 5.

Hi All, is there someone that can give me some tips to implement temporary

It seems that authentication throttling is something really different. If I got 
it, authentication throttling is used to temporary inhibit successful 
authentication attempts after a failed one.

For example, with a configuration like as

  *   failureThreshold: 3
  *   failureRangeInSeconds: 300

If a failed authentication attempt occurs, all the following attempts will 
fails (resulting in 423) for 100 seconds (300/3 -> thresholdRate 0.01).


As anticipated, I would lockout a user after 3 consecutive failed login 
attempts occurred within 60 seconds. Is it possible?

Thank you in advance for your help.

BR,

F.
