我正在构建一个具有 LDAP 身份验证的 LTSP 环境。我已经完美配置了 LTSP、LDAP 服务器和客户端。我getent passwd在 LTSP/LDAP 客户端中使用命令进行了检查。我可以看到我的 LDAP 用户详细信息。
当我启动 LTSP 瘦客户端时，我能够使用 LDAP 用户凭据登录Alt+Ctrl+F1模式。但是，无法通过 GUI（lightdm）登录。查看来自 LTSP/LDAP 客户端的日志。

如何解决这个问题？
答案1
在客户端运行以下命令：
#authconfig-gtk
现在，尝试将身份验证配置设置为 LDAP 密码（在“身份和身份验证”选项卡中）。对我来说，这个方法有效。
