我们有一个 CentOS 7.7 系统，它使用 realmd/sssd 加入 Microsoft AD 域。 Sudo 对于本地系统用户来说确实工作得很好，但是当我们尝试将 sudo 作为 Active Directory 用户 (ocftest) 使用时，我们会收到以下错误：
sudo: PAM account management error: Permission denied
我们使用以下版本的 sudo：sudo-1.8.23-9.el7.x86_64.rpm
用户可以使用其密码完美地“ssh”到系统。经过一番谷歌搜索后，这个问题会出现几次，通常是指将以下内容添加到“/etc/security/access.conf”文件中：
+ : ocftest : ALL
- : ALL : ALL
具有相同名称的用户组（尽管我已经尝试过该用户）存在于“/etc/sudoers.d/salt”文件中：
%[email protected] ALL=(ALL) ALL
只是为了完整性：

尝试在第一次出现后添加no_access_check到/etc/pam.d/system-auth（应该是到 的链接）/etc/pam.d/system-auth-acaccount sufficient pam_vas3.so
# cat system-auth-ac
...
account sufficient pam_vas3.so no_access_check
...
