Well, SSL is able to authenticate the clients, too, with client X.509
certificates, which is supposed to be a strong authentication mechanism, but
it is not always feasible to distribute certificates to clients. Sometimes a
login/password is more practical.

Yes, the server side should be able to log the failed client authentication
attempts and disable the account if necessary. That's what I am looking for,
a solution for Apache that supports this feature out of the box...
