用户“[email protected]”未满足 PBIS auth.log 要求“user ingroup nopasswdlogin”

Question

我想使用我的 Windows AD 凭据登录 Ubuntu 16.04 计算机。我使用 Beyondtrust 版本 8.5.2.265 的 PBIS（PowerBroker Identity Services）AD-bridge。 Windows版本是Windows Server 2012 R2。

这些错误会在 /var/log/auth.log 中弹出：

我已更改配置选项 RequireMembershipOf 以匹配我从 /opt/pbis/bin/enum-groups 复制的安全组“domain^users”

我解决了同样的问题。我有

pam_succeed_if(lightdm:auth)：用户“xxxxxxx”未满足“用户组内 nopasswdlogin”要求

环境为AD认证，Windows 2016，ubuntu 16.04。

解决方案

编辑/etc/pam.d/lightdm并nopasswdlogin从此行中删除：

auth    sufficient      pam_succeed_if.so user ingroup nopasswdlogin
