我有一个新的 ldap 设置，并且我正在尝试登录，无论是登录到机器的目录还是通过 SSH 远程登录。
当我尝试实际登录时，我的身份验证失败。
如果我以本地用户 (root) 登录，则成功。登录后，我可以轻松发出 su user 并切换到该用户。
运行 getent passwd 将返回所有有效用户。
有什么帮助吗？
日志显示：

Apr 10 11:50:00 ldaptest login: pam_ldap: error trying to bind (No such object)
Apr 10 11:50:03 ldaptest login: FAILED LOGIN 1 FROM (null) FOR user, Authentication failure
谢谢！

答案1
required pam_deny.so必须是每个部分的最后一行。
