红帽全球峰会37.2. 通过修改 Default Trust View 为 AD 用户定义全局属性
如果要在整个 IdM 部署中覆盖活动目录(AD)用户的 POSIX 属性，请在 Default Trust View 中修改该用户的条目。这个过程将 AD 用户 ad_user@ad.example.com 的 GID 设为 732000006。
先决条件
- 您已作为 IdM 管理员进行了身份验证。
- 具有 GID 的组必须存在，否则您必须在组的 ID 覆盖中设置 GID。
流程
作为 IdM 管理员，在 Default Trust View 中为 AD 用户创建一个 ID 覆盖，其将 GID 号更改为 732000006：
ipa idoverrideuser-add 'Default Trust View' ad_user@ad.example.com --gidnumber=732000006
# ipa idoverrideuser-add 'Default Trust View' ad_user@ad.example.com --gidnumber=732000006Copy to Clipboard Copied! Toggle word wrap Toggle overflow 从所有 IdM 服务器和客户端上的 SSSD 缓存中清除
ad_user@ad.example.com用户的条目。这会删除过时的数据，并允许应用新的覆盖值。sssctl cache-expire -u ad_user@ad.example.com
# sssctl cache-expire -u ad_user@ad.example.comCopy to Clipboard Copied! Toggle word wrap Toggle overflow
验证
检索
ad_user@ad.example.com用户的信息以验证 GID 是否反映了更新的值。id ad_user@ad.example.com
# id ad_user@ad.example.com uid=702801456(ad_user@ad.example.com) gid=732000006(ad_admins) groups=732000006(ad_admins),702800513(domain users@ad.example.com)Copy to Clipboard Copied! Toggle word wrap Toggle overflow
