<h2>Common Problem #3: How do I disable a user after a number of failed logins?</h2>
<p>A common user requirement is to disable / lock an account after a number of failed login attempts.
Acegi itself does not provide anything "out of the box", however in your application you can implement
and register an <tt>org.springframework.context.ApplicationListener</tt>. Inside your application
event listener you can then check for an instanceof the particular <tt>AuthenticationFailureEvent</tt>
and then call your application user management interface to update the user details.
<p>
For example:
<pre>
public void onApplicationEvent(ApplicationEvent event) {
// check failed event
if(event instanceof AuthenticationFailurePasswordEvent){
// call user management interface to increment failed login attempts, etc.
. . .
}
}
</pre>

<h2>Common Problem #4: I am changing my password using a web controller and DAO, why is my password still not being refreshed?</h2>
<p>There are three things you must do to make a user password change take affect:
<ul>
<li> Change the password using your authentication DAO</li>
<li> Remove the user from the User Cache (i.e. if you have a cache configured) </li>
<li> Update the <tt>ContextHolder</tt> to include the new <tt>Authentication</tt> object and password</li>
</ul>
