The simplest was to hook into the authentication process is to provide your own AuthenticationProvider. There are only two methods to implement. In authenticate() you can do all of your custom stuff.

To configure your provider into the framework do something like:

<authentication-manager>
  <authentication-provider ref="myAuthenticationProvider" />
</authentication-manager>
