security - Spring Security Kerberos Windows 身份验证中的错误

标签 security spring-security active-directory 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。如中所述
http://docs.spring.io/spring-security-kerberos/docs/1.0.1.RELEASE/reference/htmlsingle/#setupwinkerberos

为了确认一切设置正确，我正在尝试运行 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(简称 AD 服务器)域 Controller ，Windows 2008 R2 64 位
计算机名称:adjavatest1
计算机全名:adjavatest1.test.company.info
用户:TEST\管理员

客户端 PC，Windows 7
计算机名称:adjavatest2
计算机全名:adjavatest2.test.company.info
用户:TEST\管理员

应用服务器(简称 Web 服务器)
计算机名称:kpiq-dev
计算机全名:kpiq-dev.test.company.info
用户:TEST\管理员

到目前为止，我已经完成了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

(许多来源建议创建 SPN“HTTP/adjavatest1”和“HOST/adjavatest1”——我试过没有任何区别。)

2) 在 AD 服务器上验证 SPN
>setspn -L TEST\administrator
Registered ServicePrincipalNames for CN=Administrator,CN=Users,DC=test,DC=company,DC=info:
HTTP/adjavatest1.test.company.info

3)映射用户/服务并在AD服务器上生成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
Targeting domain controller:  adjavatest1.test.company.info
Using legacy password setting method
Successfully mapped HTTP/adjavatest1.test.company.info to Administrator.

Output keytab to .\ adjavatest1.HTTP.keytab:

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

5) 验证 Web 服务器上的 key 表
使用麻省理工学院 kerberos 工具的 kinit
c:\SpringSSO>kinit -V -k -t adjavatest1.HTTP.keytab HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO
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 key 表:adjavatest1.HTTP.keytab
已通过 Kerberos v5 身份验证
使用 jdk 中的 kinit
c:\SpringSSO>kinit -k -t adjavatest1.HTTP.keytab HTTP/adjavatest1.test.company.info@TEST.COMPANY.INFO
新票存储在缓存文件 C:\Users\administrator.TEST\krb5cc_administrator

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

8) 从 https://github.com/spring-projects/spring-security-kerberos/tree/master/spring-security-kerberos-samples 中构建 spring-security-kerberos-samples\sec-server-win-auth 应用程序
使用 application.yml 中的配置属性
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}))"

9) 将 Spring boot 应用部署到 Web Server 的 C:\SpringSSO 目录

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.BUILD-SNAPSHOT.jar

krb5.conf 中的 Kerberos 配置(我尝试了不同的编码类型，“arcfour-hmac-md5”只是最后一次实验)
[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
将浏览器指向 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 Server 上的日志，表明服务器无法编码

为什么安全尝试加密 Aes256CtsHmacSha1EType，而不是 rc4-hmac？
有什么建议我接下来可以尝试吗？

先感谢您。

最佳答案

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

第一个解决方案:

  • 在第 8 点)添加应用程序:
    kerberos-conf:/home/xyz/krb5.conf 在 application.yaml
  • 在 spring 安全项目中创建附加类
        @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;
        }

    }
