Using a custom form for Spring Security Waffle authentication instead of the browser popup

[Zahro Alfelpha]

I am creating a Spring MVC application that authenticates using Waffle. I have successfully configured it and it works just fine, but I would like to use a custom form instead of the browser popup when the browser does not automatically send their network credentials.

I have modified my configuration to use `formLogin()` hoping that it would use my existing authentication, but no luck.

package com.barrygold.waffledemo;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.EnableWebSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
import org.springframework.security.web.authentication.www.BasicAuthenticationFilter;

import waffle.spring.NegotiateSecurityFilter;
import waffle.spring.NegotiateSecurityFilterEntryPoint;

@Configuration
@EnableWebSecurity
public class SecurityConfiguration extends WebSecurityConfigurerAdapter{

    @Autowired
    private NegotiateSecurityFilterEntryPoint authenticationEntryPoint;

    @Autowired
    private NegotiateSecurityFilter securityFilter;

    @Override
    protected void configure(final HttpSecurity http) throws Exception {
        http
        	.authorizeRequests()
                .anyRequest().authenticated()
            .and()
            	.addFilterBefore(this.securityFilter, BasicAuthenticationFilter.class)
            	.httpBasic()
                .authenticationEntryPoint(this.authenticationEntryPoint)
            .and()
        		.formLogin();
            
    }

}

This would be the ideal behavior:

Major Progress! I have successfully got the form to authenticate using Windows network credentials. Here's how I did it:

First of all, let me show you the bean declarations I left out of my original post. They are located in a separate class.

    // Waffle Spring Security Beans
    @Bean
    public WindowsAuthProviderImpl windowsAuthProvider() {
    	return new WindowsAuthProviderImpl();
    }
    @Bean
    @Autowired
    public NegotiateSecurityFilterProvider negotiateSecurityFilterProvider(final WindowsAuthProviderImpl windowsAuthProvider) {
    	return new NegotiateSecurityFilterProvider(windowsAuthProvider);
    }
    @Bean
    @Autowired
    public SecurityFilterProviderCollection waffleSecurityFilterProviderCollection(final NegotiateSecurityFilterProvider negotiateSecurityFilterProvider) {
    	final List<SecurityFilterProvider> securityFilterProviders = new ArrayList<SecurityFilterProvider>();
    	securityFilterProviders.add(negotiateSecurityFilterProvider);
    	return new SecurityFilterProviderCollection(securityFilterProviders.toArray(new SecurityFilterProvider[]{}));
    }
    @Bean
    @Autowired
    public NegotiateSecurityFilterEntryPoint negotiateSecurityFilterEntryPoint(final SecurityFilterProviderCollection securityFilterProviderCollection) {
    	final NegotiateSecurityFilterEntryPoint negotiateSecurityFilterEntryPoint = new NegotiateSecurityFilterEntryPoint();
    	negotiateSecurityFilterEntryPoint.setProvider(securityFilterProviderCollection);
    	return negotiateSecurityFilterEntryPoint;
    }
    @Bean
    @Autowired
    public NegotiateSecurityFilter waffleNegotiateSecurityFilter(final SecurityFilterProviderCollection securityFilterProviderCollection) {
    	final NegotiateSecurityFilter negotiateSecurityFilter = new NegotiateSecurityFilter();
    	negotiateSecurityFilter.setProvider(securityFilterProviderCollection);
    	return negotiateSecurityFilter;
    }
    @Bean
    public WaffleAuthenticationDetailsSource waffleAuthenticationDetailsSource() {
    	return new WaffleAuthenticationDetailsSource();
    }

Now, this is how I got the generated spring security form to authenticate with Windows network credentials

First, I added this bean of type `waffle.spring.WindowsAuthenticationProvider`

    @Bean
    @Autowired
    public WindowsAuthenticationProvider windowsAuthenticationProvider(final WindowsAuthProviderImpl windowsAuthProvider) {
    	WindowsAuthenticationProvider provider = new WindowsAuthenticationProvider();
    	provider.setAuthProvider(windowsAuthProvider);
    	return provider;
    }

Then I added it to `SecurityConfig.java` and used it to set the authentication provider in the http security chain

    ...
    
    @Autowired
    public WindowsAuthenticationProvider windowsAuthenticationProvider;
    
    @Override
    protected void configure(final HttpSecurity http) throws Exception {
    	http
    		.authorizeRequests()
    			.anyRequest().authenticated()
    		.and()
    			.addFilterBefore(this.securityFilter, BasicAuthenticationFilter.class)
    			.httpBasic()
    			.authenticationEntryPoint(this.authenticationEntryPoint)
    		.and()
    			.authenticationProvider(windowsAuthenticationProvider) // Set authentication provider here
    			.formLogin()
    			.authenticationDetailsSource(waffleAuthenticationDetailsSource);
    		
    }

Now I just have to figure out how to only use the form if the browser doesn't send the credentials! Hmmmm....
