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：
