Dns 在CentOS中使用/etc/resolv.conf解析AD域

我已使用Realm配置SSSD，以使用AD凭据登录centOS VM。请参考设置

我不得不修改/etc/resolv.conf文件，将namserver指向AD域

原始/etc/resolv.conf文件：

# Generated by NetworkManager
search ap-south-1.compute.internal
nameserver 172.31.0.2

# Generated by NetworkManager
search test.com
nameserver 172.31.12.38

更新了/etc/resolv.conf文件：

# Generated by NetworkManager
search ap-south-1.compute.internal
nameserver 172.31.0.2

# Generated by NetworkManager
search test.com
nameserver 172.31.12.38

通过更新的/etc/resolv.conf文件，用户可以使用AD凭据登录，但原始域未解析

我想要一种方法来解析指向不同名称服务器的两个域

# Generated by NetworkManager
nameserver 172.31.0.2
nameserver 172.31.12.38
search ap-south-1.compute.internal test.com

我也尝试了多种方法来使用不推荐使用的标记解析域

# Generated by NetworkManager
domain ap-south-1.compute.internal
nameserver 172.31.0.2

domain test.com
nameserver 172.31.12.38

我甚至尝试过旋转选项

# Generated by NetworkManager
options rotate
options timeout:1
nameserver 172.31.0.2
nameserver 172.31.12.38
search ap-south-1.compute.internal test.com

有没有办法使用/etc/resolv.conf解析指向不同名称服务器的多个域要解析AD林域，我们可以在sssd.conf文件中配置AD_服务器参数

参考链接：[参考ad_服务器部分]

/etc/sssd/sssd.conf参考文件：

原始文件：

[sssd]
domains = test.com
config_file_version = 2
services = nss, pam, sudo, ssh

[nss]
debug_level = 10

[domain/test.com]
ad_domain = test.com
krb5_realm = TEST.COM
realmd_tags = manages-system joined-with-adcli 
cache_credentials = True
id_provider = ad
krb5_store_password_if_offline = True
default_shell = /bin/bash
ldap_id_mapping = True
use_fully_qualified_names = False
fallback_homedir = /home/%u
access_provider = simple
ldap_user_extra_attrs = altSecurityIdentities:altSecurityIdentities
ldap_user_ssh_public_key = altSecurityIdentities
ldap_use_tokengroups = True

更新文件：

[sssd]
domains = test.com
config_file_version = 2
services = nss, pam, sudo, ssh

[nss]
debug_level = 10

[domain/test.com]
ad_domain = test.com
ad_server = 172.31.12.38, 172.31.12.48
krb5_realm = TEST.COM
realmd_tags = manages-system joined-with-adcli 
cache_credentials = True
id_provider = ad
krb5_store_password_if_offline = True
default_shell = /bin/bash
ldap_id_mapping = True
use_fully_qualified_names = False
fallback_homedir = /home/%u
access_provider = simple
ldap_user_extra_attrs = altSecurityIdentities:altSecurityIdentities
ldap_user_ssh_public_key = altSecurityIdentities
ldap_use_tokengroups = True

通过这种方式，我们可以避免在/etc/resolv.conf文件中创建任何条目

我认为您需要的是。另一个不太推荐的选项是使用转发区域配置您的本地DNS。此处给出了绑定DNS服务器的示例：
