active-directory – SSSD Kerberos AD Centos故障排除

我按照RedHat AD集成中的配置3( https://access.redhat.com/sites/default/files/attachments/rhel-ad-integration-deployment-guidelines-v1.5.pdf);但我被卡住了.

我在Centos 6.8上.

我有一个有效的AD连接​​：

service sssd stop
 rm -r /var/lib/sss/db/*
 rm -r /var/lib/sss/mc/*
 service sssd start
 getent passwd robau@MYNETWORK.LOCAL

这返回了一条明智的路线：

robau:*:102201201:102200513:Rob Audenaerde:/:

但是,当我尝试通过SSH连接时,我无法登录.我在sssd.conf中的所有组件级别5上启用了SSSD调试.

我看到的错误(在var / log / sssd / krb5_child.log中)是：

(Fri Jun 17 17:23:18 2016) [[sssd[krb5_child[3561]]]] [validate_tgt] (0x0020): TGT Failed verification using key for [host/server-new.mynetwork.nl@MYNETWORK.LOCAL].
(Fri Jun 17 17:23:18 2016) [[sssd[krb5_child[3561]]]] [get_and_save_tgt] (0x0020): 1240: [-1765328377][Server not found in Kerberos database]

服务器在DNS中,我可以使用nslookup找到它

nslookup server-new.mynetwork.nl

   Server:  192.168.110.56
   Address: 192.168.110.56#53

   Name:    server-new.mynetwork.nl
   Address: 192.168.210.94

和

kvno host/server-new.mynetwork.nl@MYNETWORK.LOCAL
kvno: Server not found in Kerberos database while getting credentials for host/server-new.mynetwork.nl@MYNETWORK.LOCAL

有关故障排除的任何提示/提示？

我用authconfig来设置必要的pam和nss东西：

authconfig --enablesssdauth --enablesssd --enablemkhomedir --update

输出klist -kte：

如果我在sssd.conf部分[domain / mynetwork.local]的末尾添加krb5_validate,那么我就可以登录了.但是,我还设置了另一台不需要这个步骤的服务器,所以我不愿意这样做.

在网络广告加入-k期间,我收到错误/警告：

DNS Update for Failed: ERROR_DNS_GSS_ERROR 
DNS update Failed!

[编辑4]
我看到网络广告信息的输出没有使用我在配置文件中指定的主域控制器(并且是2003R2而不是2008R2).有没有办法“强制”网络广告加入-k使用特定的域控制器？

yum -y --enablerepo=epel install msktutil

msktutil --auto-update --server my-ad --verbose

kinit -k server-new$
