使用Ubuntu 10.04进行PAM / LDAPauthentication

我无法将自己的大脑围绕Ubuntu 10.04中使用的新的pam.dconfiguration语法。 如何设置PAM，以便允许存储在我的LDAP数据库中的用户login。

我已经configuration了nscd，所以id <user>或getent passwd已经列出了我的LDAP用户，但是PAM不起作用，无论是正常的shelllogin还是su 。

LDAP已经在工作。 我可以通过执行getent passwd来列出所有帐户，但是我的PAMconfiguration仍然不起作用。

• 如何通过pam_tally2为特定用户设置密码locking例外？
• 将Red Hat Linux 6joinWindows Active Directory域
• 允许域用户*和*本地用户到Centos 7服务器
• 我可以同时使用RSA 2因子PAM和Active Directory PAM吗？
• pam_cracklib正确报告错误的密码，但是pam_unix模块仍然会更改密码
