Pour la mise en œuvre fournisseur d'authentification ldap personnalisée, vous devez créer la classe qui va de AbstractLdapAuthenticator
public class BindPasswordAuthentificator extends AbstractLdapAuthenticator {
public BindPasswordAuthentificator(BaseLdapPathContextSource contextSource) {
super(contextSource);
}
@Override
public DirContextOperations authenticate(Authentication authentication) {
DirContextOperations user;
String username = authentication.getName();
String password = (String)authentication.getCredentials();
user = authenticateByLdap(username, password); // authenticate user here
if (user == null) {
throw new BadCredentialsException(
messages.getMessage("BindAuthenticator.badCredentials", "Bad credentials"));
}
return user;
}
}
Et pour la mise en œuvre des autorités ldap vous Populator besoin de créer la classe qui va de LdapAuthoritiesPopulator
public class CustomLdapAuthoritiesPopulator implements LdapAuthoritiesPopulator {
@Override
public Collection<? extends GrantedAuthority> getGrantedAuthorities(DirContextOperations userData, String username) {
Collection<GrantedAuthority> gauth = new HashSet<>();
//you need to place logic for populating user authorities here
return gauth;
}
}
Ensuite, vous devez configurer ces deux classes dans votre configuration
@Configuration
@PropertySource("classpath:application.properties")
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
@Value("${life.ldap.server}")
private String ldapServer;
@Autowired
public void globalUserDetails(final AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(ldapAuthenticationProvider());
}
@Bean
public LdapAuthenticationProvider ldapAuthenticationProvider() {
return new LdapAuthenticationProvider(authentificator(), authPopulator());
}
@Bean
public BindPasswordAuthentificator authentificator() {
return new BindPasswordAuthentificator(contextSource());
}
@Bean
public DefaultSpringSecurityContextSource contextSource() {
return new DefaultSpringSecurityContextSource(ldapServer);
}
@Bean
public CustomLdapAuthoritiesPopulator authPopulator() {
CustomLdapAuthoritiesPopulator result = new CustomLdapAuthoritiesPopulator();
return result;
}
@Override
@Bean
public AuthenticationManager authenticationManagerBean() throws Exception {
return super.authenticationManagerBean();
}
@Override
protected void configure(final HttpSecurity http) throws Exception {
http.authorizeRequests().antMatchers("/login").permitAll()
.antMatchers("/oauth/token/revokeById/**").permitAll()
.antMatchers("/tokens/**").permitAll()
.anyRequest().authenticated()
.and().formLogin().permitAll()
.and().csrf().disable();
}
}
