尝试使 Windows Server 2016 Active Directory + Kerberos 和 Java OpenJDK 8 kinit 获得票证授予票证返回KrbException:标识符与预期值不匹配(906)
我有两台 Azure VM,我想使用 Windows Server 2016 获取 kinit 票证授予票证,一台在 10.0.1.4,另一台在 10.0.1.7。
这10.0.1.4VM 包含具有 LDAP 和 DNS 服务器的 Active Directory。计算机名称为操作系统。因此 Active Directory 域控制器是WinServer2016Fo.corp.demo.comKerberos 密钥分发中心是WINSERVER2016FO.CORP.DEMO.COM,据我理解这是域控制器名称,全部大写。
这10.0.1.7VM 包含 Java OpenJDK 8。计算机名称是演示机器。我已经通过 Telnet 验证,我可以使用端口 88(Kerberos 使用的端口)从 10.0.1.7 连接到 WinServer2016Fo.corp.demo.com(10.0.1.4)。
域名是corp.demo.com,我为该域创建了一个名为演示Http使用密码演示Http
我已经链接了用户演示Http到演示机器使用设置spn如下:
setspn -S HTTP/demoMachine.corp.demo.com demoHttp
然后我创建了 krb5.keytab,如下所示:
ktpass -out krb5.keytab -princ HTTP/[email protected] -mapUser demoHttp -mapOp set -pass demoHttp -crypto RC4-HMAC-NT -ptype KRB5_NT_PRINCIPAL
10.0.1.7(demo.corp.demo.com VM)上的 krb5.ini:
[libdefaults]
default_realm = CORP.DEMO.COM
default_keytab_name = FILE:c:\Windows\krb5.keytab
default_tkt_enctypes = rc4-hmac
default_tgs_enctypes = rc4-hmac
forwardable = true
renewable = true
noaddresses = true
clockskew = 300
udp_preference_limit = 1
allor_weak_crypto = true
[realms]
CORP.DEMO.COM = {
kdc = WinServer2016Fo.corp.demo.com:88
default_domain = corp.demo.com
}
[domain_realm]
corp.demo.com = CORP.DEMO.COM
问题是当我尝试运行时基尼特使用 OpenJDK 8:
kinit.exe "-J-Dsun.security.krb5.debug=true" -k -t C:\Windows\krb5.keytab HTTP/demoMachine.corp.demo.com
它引发以下异常:
