之前看到了这个帖子https://bbs.csdn.net/topics/320243668，解决了我的问题，但是那个帖子比较久了，不能回复了，所以我这里再开一个，希望能帮助到需要的人

客户端连接的时候提示输入用户名密码后，验证不成功又跳出输入用户名密码的对话框，请大虾帮忙，谢谢。下面是服务器的输入信息：

另外：我的OpenVPN用生成的key文件可以正常连接服务器，而且testsaslauth -u tom -p foo -s openvpn能验证成功，返回：0: OK "Success."。
我认为是关键地方是这句：AUTH-PAM: BACKGROUND: user 'tom' failed to authenticate: Module is unknown，但不知道怎样解决，openvpn-auth-pam.so的权限也是755.请大虾帮忙，非常感谢！
