BasicAuthenticationFilter

To implement our Basic authentication, we have added BasicAuthenticationFilter to our filter chain. This BasicAuthenticationFilter (org.sfw.security.web.authentication.www.BasicAuthenticationFilter) requires an authenticationManager and optionally an authenticationEntryPoint.

The optional configuration of an authenticationEntryPoint drives the filter towards two different behaviours presented next.

Both starts the same way: the filter is triggered from its position in the chain. It looks for the authentication header in the request and delegates to the authenticationManager, which then relies on the UserDetailsService implementation to compare it with the user credentials from the database.
