Spring Security Kerberos Windows 身份验证错误

Ale*_*eiP 5 security active-directory spring-security spnego spring-security-kerberos

我正在尝试在我们的环境中设置基于 Spring 的安全 Web 应用程序。如http://docs.spring.io/spring-security-kerberos/docs/1.0.1.RELEASE/reference/htmlsingle/#setupwinkerberos中所述

为了确认一切设置正确，我尝试运行 Spring Boot Security 示例应用程序（按照此处所述构建：http ://docs.spring.io/spring-security-kerberos/docs/1.0.1.RELEASE/reference /htmlsingle/#samples-sec-server-win-auth）

这是我们在 TEST 域下的测试环境：

Active Directory（称为 AD 服务器）域控制器，Windows 2008 R2 64 位
计算机名称：adjavatest1
计算机完整名称：adjavatest1.test.company.info
用户：TEST\administrator

客户端 PC，Windows 7
计算机名称：adjavatest2
计算机完整名称： adjavatest2.test.company.info
用户：TEST\administrator

应用程序服务器（称为 Web 服务器）
计算机名称：kpiq-dev
完整计算机名称：kpiq-dev.test.company.info
用户：TEST\administrator

到目前为止，我已执行以下步骤来配置环境和应用程序

1）在AD服务器上设置SPN

setspn -A HTTP/adjavatest1.test.company.info TEST\administrator
Run Code Online (Sandbox Code Playgroud)

（许多来源建议创建 SPN“HTTP/adjavatest1”和“HOST/adjavatest1” - 我已经尝试过，没有任何区别。）

2) 验证AD服务器上的SPN

>setspn -L TEST\administrator
Registered ServicePrincipalNames for CN=Administrator,CN=Users,DC=test,DC=company,DC=info:
HTTP/adjavatest1.test.company.info
Run Code Online (Sandbox Code Playgroud)

3) 在AD Server上映射用户/服务并生成keytab文件

>ktpass -princ HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO -pass pswd123 -mapuser TEST\Administrator -out .\ adjavatest1.HTTP.keytab -ptype KRB5_NT_PRINCIPAL -crypto All

4) 将 keytab 文件复制到 Web Server 的 C;\SpringSSO 目录中


5)使用 MIT kerberos 工具 c:\SpringSSO>kinit -V -k -t adjavatest1.HTTP.keytab HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO 中的 kinit验证 Web 服务器上的密钥表使用现有缓存：初始默认 ccache 使用主体：HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO 使用 keytab：adjavatest1.HTTP.keytab 通过 Kerberos v5 进行身份验证 使用 jdk c:\SpringSSO>kinit -k -t adjavatest1.HTTP 中的 kinit。 keytab HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO 新票证存储在缓存文件 C:\Users\administrator.TEST\krb5cc_administrator 中

6) 在两个位置的 Web 服务器上的 jre/lib/security 中安装“Kerberos 和无限强度策略”：

c:\Program Files\Java\jre1.8.0_65\lib\security\
c:\Program Files\Java\jdk1.8.0_65\jre\lib\security\

7) 检查 Web 服务器上的 Windows 注册表：

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\Kerberos\
Value Name: allowtgtsessionkey
Value: 0x1
Run Code Online (Sandbox Code Playgroud)

8) 构建 spring-security-kerberos-samples\sec-server-win-auth 应用程序，取自https://github.com/spring-projects/spring-security-kerberos/tree/master/spring-security-kerberos-samples 在 application.yml 中使用配置属性

server:
    port: 80
app:
    ad-domain: TEST.COMPANY.INFO
    ad-server: ldap://ADJAVATEST1.TEST.COMPANY.INFO/
    service-principal: HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO
    keytab-location:  adjavatest1.HTTP.keytab
    ldap-search-base: DC=TEST,DC=COMPANY,DC=INFO
    ldap-search-filter: "(| (userPrincipalName={0}) (sAMAccountName={0}))"
Run Code Online (Sandbox Code Playgroud)

9) 将 Spring boot 应用程序部署到 C:\SpringSSO 目录中的 Web Server

10) 在 Web 服务器上启动 Web 应用程序 c:\SpringSSO>java -Dsun.security.krb5.debug=true -Djava.security.krb5.conf=.\krb5.conf -jar sec-server-win-auth-1.0。 2.构建快照.jar

krb5.conf 中的 Kerberos 配置（我尝试了不同的 enctypes，“arcfour-hmac-md5”只是最后一个实验）

[libdefaults]
 default_realm = TEST.COMPANY.INFO
 permitted_enctypes = arcfour-hmac-md5 rc4-hmac aes256-cts aes128-cts des3-cbc-sha1 des-cbc-md5 des-cbc-crc
 default_tgs_enctypes = arcfour-hmac-md5 rc4-hmac aes256-cts aes128-cts des3-cbc-sha1 des-cbc-md5 des-cbc-crc
 default_tkt_enctypes = arcfour-hmac-md5 rc4-hmac aes256-cts aes128-cts des3-cbc-sha1 des-cbc-md5 des-cbc-crc
 dns_lookup_kdc = true
 dns_lookup_realm = false

[realms]
 TEST.COMPANY.INFO = {
     kdc =  ADJAVATEST1.TEST.COMPANY.INFO
     admin_server =  ADJAVATEST1.TEST.COMPANY.INFO
     master_kdc =  ADJAVATEST1.TEST.COMPANY.INFO
     default_domain = TEST.COMPANY.INFO
 }

[domain_realm]
 .TEST.COMPANY.INFO = TEST.COMPANY.INFO
 TEST.COMPANY.INFO = TEST.COMPANY.INFO

11) 在客户端的IE浏览器中将路径*.test.company.info添加到IE浏览器作为内网模式点浏览器到http://kpiq-dev.test.company.info/hello

12) 将浏览器指向 http://kpiq-dev.test.company.info/hello

13) 检查Web服务器上的日志表明服务器无法编码

为什么安全性尝试加密 Aes256CtsHmacSha1EType，而不是 rc4-hmac？
有什么建议我下一步可以尝试吗？

先感谢您。

两个可能的错误：

1) krb5.conf 未正确加载

2) 服务主体配置不正确

第一个的解决方案：

  • 在第8点）在application.yaml中添加应用程序： kerberos-conf：/home/xyz/krb5.conf

  • 在 Spring Security 项目中创建附加类

        @Configuration
    public class KerberosGlobalConfig {

        @Value("${app.kerberos-conf}")
        private String kerberosGlobalConfPath;

        @Bean
        public GlobalSunJaasKerberosConfig globalSunJaasKerberosConfig() {
            GlobalSunJaasKerberosConfig globalSunJaasKerberosConfig = new 
            GlobalSunJaasKerberosConfig();
            //TODO remove hardcoding
            globalSunJaasKerberosConfig.setDebug(true);
            globalSunJaasKerberosConfig.setKrbConfLocation(kerberosGlobalConfPath);
            return globalSunJaasKerberosConfig;
        }

    }
