Hi,
I have implemented CAS 6.0.0 with succes so far.
After doing connexion attempts with a wrong password, I am happy to see the page "Too many attempts ...."
However I am NOT blocked. I can immediatly perform a succesfull connexion with the correct password with the same browser on a new page.
## extract of cas.properties ##
cas.authn.throttle.usernameParameter=
cas.authn.throttle.schedule.startDelay=PT10S
cas.authn.throttle.schedule.repeatInterval=PT120S
cas.authn.throttle.appCode=CAS
cas.authn.throttle.failure.threshold=30
cas.authn.throttle.failure.code=AUTHENTICATION_FAILED

cas.authn.throttle.bucket4j.rangeInSeconds=60
cas.authn.throttle.bucket4j.capacity=120

Baso,
AUTHENTICATION_EVENT_TRIGGERED happens any time cas/login is accessed.
What happens when you try to log in?

Ray,
Scenario I have done :
1/ After serveral attempts with a wrong password, I obtain the page "Too many attempts ...."
2/ Then I open a new window https://xxxxx/cas/login (I am NOT blocked) and make another attemps with a wrong password.
3/ Once again after several attemps I obtain the page "Too many attempts ...."
4/ Then I open a new window https://xxxxx/cas/login (I am NOT blocked) and make another attemps with a correct password.
5/ I am granted access
Here below the trace
