Re: [keycloak-dev] AbstractUsernameFormAuthenticator validateUserAndPassword process
AFAIK one of the reasons is security. If an attacker guesses username
"foo", which exists, but not password of user "foo", you don't
want to
tell him that he successfully guessed username. So instead of first
checking that user "foo" is disabled and display the message "The user
account is disabled", you rather check password first and then display
the message "Incorrect username or password", so attacker don't have a
clue if account really exists or password was incorrect etc. Also if
BruteForce protector is enabled, you want to log the event as failed
login, so we're checking the password of user.

Hi, I am developing a Federation Provider, and I have a question...
Why the method () checks if the user "is enabled" after validate the
password instead of before of the password validation?

If the user is disabled... why validate his password and return a
password validation error message?
