Authentication with Active Directory in a Spring Boot application is straightforward and requires minimal setup. You don't need to install an embedded server for testing connectivity or additional complex packages. In fact, the process is streamlined with just a couple of dependencies and a simple configuration.
Dependencies
First, ensure you have the necessary dependencies in your pom.xml or build.gradle:
<dependency>
<groupId>org.springframework.security</groupId>
<artifactId>spring-security-ldap</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-ldap</artifactId>
</dependency>
Configuration
Next, configure your Spring Security in a WebSecurityConfig class:
@EnableWebSecurity
public class WebSecurityConfig{
@Bean
SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
http
.authorizeHttpRequests((authorize) -> authorize.anyRequest().fullyAuthenticated())
.formLogin(Customizer.withDefaults());
return http.build();
@Bean
public ActiveDirectoryLdapAuthenticationProvider authenticationProvider() {
return new ActiveDirectoryLdapAuthenticationProvider("domain.com", "ldap://ip-addr");
}
}
And that's it, happy securing 😎 !!
