我正在准备从CentOS 6到CentOS 7的最终升级.现在,在版本6中,我们只使用LDAP映射到AD进行身份验证.然后,它使用Unix的Active Directory扩展中的UID和GID.
在我对CentOS 7的实验中,我通过文档(我认为它来自Red Hat)解释了如何加入域.这个过程大多是直截了当的,而且大多数都很有效.但是,它不仅仅使用AD Unix属性中的UID和GID.它将这些ID映射到完全不同的ID.在AD中,用户在10000范围内. CentOS7为每个用户提供625000000范围内的UID.
到目前为止,在我的小规模测试(3个盒子)中,UID似乎在所有这些中都是一致的,这很好.但是,当我开始在生产中推出7个时,它将逐步升级.我不会同时升级每个盒子.我担心用户在不同的盒子上有不同的UID.有没有办法让CentOS 7在AD Unix属性中使用UID和GID?
这是我的smb.conf:
- [global]
- workgroup = COMPANY
- client signing = yes
- client use spnego = yes
- kerberos method = secrets and keytab
- log file = /var/log/samba/%m.log
- password server = ad_domaincontroller.company.net
- realm = COMPANY.NET
- security = ads
- server string = Samba Server Version %v
- max log size = 50
这是我的sssd.conf
- [sssd]
- config_file_version = 2
- domains = company.net
- services = nss,pam,pac
- [nss]
- filter_groups = root
- filter_users = root
- [domain/company.net]
- id_provider = ad
- ad_server = ad_domiancontroller.company.net
- ad_hostname = centos7-22.company.net
- auth_provider = ad
- chpass_provider = ad
- access_provider = ad
- ldap_schema = ad
- use_fully_qualified_names = False
- cache_credentials = true
- ldap_access_order = expire
- ldap_account_expire_policy = ad
- ldap_force_upper_case_realm = true
编辑:我已经尝试将ldap_id_mapping = False添加到sssd.conf,但是包含该行,sssd.service将无法启动.这是输出:

来自sssd-ad的手册页:
默认情况下,AD提供程序将映射Active Directory中objectSID参数的UID和GID值.有关详细信息,请参阅下面的“ID映射”部分.如果要禁用ID映射,而是依赖于Active Directory中定义的POSIX属性,则应进行设置ldap_id_mapping = False
