Hello all
is it possible to block/deny the access for a user which has typed 5 times the wrong password?
So he can´t login for 5min?
Otherwise Brute-Force Attack is possbile...
Thanks for your help
Regards

Re: block user at too many wrong logins
you'd want to implement fail2ban probably ...
That's at least how I do it

Idea is pretty simple: check logfiles for pattern and if a configured number of this pattern occor in the logfile: block the user
