无法使用受信任域 AD 凭据登录 Ubuntu 服务器

无法使用受信任域 AD 凭据登录 Ubuntu 服务器

我有一个加入 AD 域的 Ubuntu 22.04 服务器。我需要能够使用来自受信任域的凭据登录到它，该受信任域附加到服务器所属的 AD 域。使用受信任的域凭据无法登录。安装了以下软件包：

winbind、krb5 用户、sssd-ad、samba

域是domain1.org 和domain2.local。 domain1.org 是我的服务器加入的域，domain2.local 是受信任的域。

我可以使用 domain1.org 凭据登录，并且以下所有命令都有效：

ping domain1.org
ping domain2.local

id [email protected]
id [email protected]
wbinfo -i [email protected]
wbinfo -i [email protected]

wbinfo -n [email protected]
net cache flush
wbinfo --sid-to-uid <SID returned in the wbinfo -n command>

我无法使用domain2.local 凭据登录此Ubuntu 服务器。我确实有一台 Rocky Linux 服务器，其设置方式与此服务器几乎相同，并且我是能够使用domain2.local凭据登录。

以下是 samba、sssd、nsswitch 和 krb5 配置：

/etc/samba/smb.conf

   dns_lookup_realm = true
   dns_lookup_kdc = true
   ticket_lifetime = 24h

我感谢任何和所有评论和/或帮助。谢谢！

首先，

apt-get purge sssd

sssd运行和是没有意义的winbind，并且您需要winbind信任。

其次，修复你的smb.conf.这是错误的：

winbind use default domain = yes
idmap config * : range = 1100-65534
idmap config * : backend = tdb
idmap config * : backend = autorid
idmap config * : range = 1000000-999999999

最后两行覆盖上面的两行，并且您不能winbind use default domain = yes与autorididmap 后端一起使用。删除上面的前三行，并提供所需的信任，它应该可以工作。
