CentOS 7.7 - sudo:PAM 帐户管理错误:权限被拒绝

CentOS 7.7 - sudo:PAM 帐户管理错误:权限被拒绝

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/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
...
