我一直在尝试将Spring Security配置为使用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的许多答案的建议创建自定义映射器,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进行身份验证并输入错误密码时,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}]
意味着活动目录正在正常工作,但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}]
任何想法如何解决这个问题?

问题似乎是因为ActiveDirectoryLdapAuthenticationProvider
正在使用域“猜测”DN。将spring-security-ldap
更新为最新版本可提供new constructor with 3 parameters,其中最后一个允许您指定DN。之后,映射器开始被成功调用,并且验证通过了。
我要感谢所有贡献的人:)

尝试使用java环境属性“java.naming.referral”设置为“follow”(在启动时的代码中,或通过JVM的参数-Djava.naming.referral = follow。
您是否获得了堆栈跟踪,或者您是否可以打印BadCredentialsException?
这与AD遇到的问题非常相似,问题在于AD如何处理引用,这会在数据检索过程中产生错误。
根据您发布的内容,我预计会在ActiveDirectoryLdapAuthenticationProvider.java line 323中生成异常,这会导致同样的问题。
