Custom Login Page through LDAP in Spring Boot - spring

Question

I want to implement LDAP authentication in my Spring Boot app. I have configuration class as below:
#Configuration
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
//#Value("${ad.domain}")
private String AD_DOMAIN;
//#Value("${ad.url}")
private String AD_URL;
WebSecurityConfig() {
AD_DOMAIN = "domain.com";
AD_URL = "ldap://URL";
}
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().fullyAuthenticated().and().formLogin().permitAll().and().logout().permitAll();
}
#Override
public void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(activeDirectoryLdapAuthenticationProvider()).userDetailsService(userDetailsService());
}
#Bean
public AuthenticationManager authenticationManager() {
return new ProviderManager(Arrays.asList(activeDirectoryLdapAuthenticationProvider()));
}
#Bean
public AuthenticationProvider activeDirectoryLdapAuthenticationProvider() {
ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider(AD_DOMAIN, AD_URL);
provider.setConvertSubErrorCodesToExceptions(true);
provider.setUseAuthenticationRequestCredentials(true);
return provider;
}
}
controller:
#Controller
public class HomeController {
#GetMapping("/")
public String index() {
Authentication auth = SecurityContextHolder.getContext().getAuthentication();
String user = auth.getName();
return "Welcome to the home page "+ user;
}
And my pom file have dependencies as :
<dependencies>
<dependency>
<groupId>org.springframework.ldap</groupId>
<artifactId>spring-ldap-core</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-ldap</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.projectlombok</groupId>
<artifactId>lombok</artifactId>
<optional>true</optional>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-security</artifactId>
</dependency>
</dependencies>
Here all is working fine I am getting SpringBoot's default login page and Authentication is also working.
But now I want a Custom login Page for that in my WebSecurityConfig class I have done the following :
#Override
protected void configure(HttpSecurity http) throws Exception {
http.authorizeRequests().anyRequest().authenticated().and().formLogin().loginPage("/login").permitAll().and().logout().permitAll();
}
where /login is my custom login page. But this is not working. I think that the AuthenticationManager is bind to the Spring's default login Page.
Can Someone suggest me, it will be helpful. Thanks
