java - Spring Security + LDAP 总是返回 BadCredentialsException

Question

我一直在尝试配置 Spring Security 以使用 LDAP，但收效甚微。

我有以下配置 bean:

@Bean
public ActiveDirectoryLdapAuthenticationProvider activeDirectoryLdapAuthenticationProvider() {

    ActiveDirectoryLdapAuthenticationProvider provider = new ActiveDirectoryLdapAuthenticationProvider("go.com.mt", "LDAP://CORPORATE.INTRA");
    provider.setConvertSubErrorCodesToExceptions(true);
    provider.setUseAuthenticationRequestCredentials(true);
    provider.setUserDetailsContextMapper(userDetailsContextMapper());
    return provider;
}

@Bean
public UserDetailsContextMapper userDetailsContextMapper() {
    UserDetailsContextMapper contextMapper = new AttributesLDAPUserDetailsContextMapper();
    return contextMapper;
}

@Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
    auth.authenticationProvider(activeDirectoryLdapAuthenticationProvider());
}

我尝试按照堆栈溢出上许多答案的建议创建一个自定义映射器，将每个权限设置为 ROLE_USER

public class AttributesLDAPUserDetailsContextMapper implements UserDetailsContextMapper {
    @Override
    public UserDetails mapUserFromContext(DirContextOperations dirContextOperations, String username, Collection<? extends GrantedAuthority> authority) {
        List<GrantedAuthority> mappedAuthorities = new ArrayList<GrantedAuthority>();
        for (GrantedAuthority granted : authority) {
            if (true) {
                mappedAuthorities.add(() -> "ROLE_USER");
            } else if(granted.getAuthority().equalsIgnoreCase("MY ADMIN GROUP")) {
                mappedAuthorities.add(() -> "ROLE_ADMIN");
            }
        }
        return new User(username, "", mappedAuthorities);
    }

    @Override
    public void mapUserToContext(UserDetails userDetails, DirContextAdapter dirContextAdapter) {

    }
}

当我尝试使用现有用户和不正确的密码进行身份验证时，我收到以下消息:

[apr-8080-exec-6] ctiveDirectoryLdapAuthenticationProvider : Active Directory authentication failed: Supplied password was invalid
[apr-8080-exec-6] o.s.b.a.audit.listener.AuditListener     : AuditEvent [timestamp=Thu Aug 20 07:31:59 CEST 2015, principal=samantha.catania, type=AUTHENTICATION_FAILURE, data={type=org.springframework.security.authentication.BadCredentialsException, message=Bad credentials}]

这意味着 Activity 目录正在正常工作，但是当我尝试使用正确的凭据进行身份验证时，我收到以下消息:

[pr-8080-exec-10] o.s.s.ldap.SpringSecurityLdapTemplate    : Ignoring PartialResultException
[pr-8080-exec-10] o.s.b.a.audit.listener.AuditListener     : AuditEvent [timestamp=Thu Aug 20 07:32:05 CEST 2015, principal=samantha.catania, type=AUTHENTICATION_FAILURE, data={type=org.springframework.security.authentication.BadCredentialsException, message=Bad credentials}]

有什么想法可以解决这个问题吗？

Answer 1

问题似乎是因为 ActiveDirectoryLdapAuthenticationProvider 使用域“猜测”DN。将 spring-security-ldap 更新到最新版本提供了 new constructor with 3 parameters其中最后一项允许您指定 DN。之后映射器开始被成功调用并且身份验证通过。

我要感谢所有做出贡献的人:)
