【问题描述】：
在成功设置 dockerized guacamole 0.9.8 之后
- http://guac-dev.org/doc/gug/guacamole-docker.html
- http://kalzi.github.io/2015/guacamole-with-docker-containers/
使用下面的脚本并使用用户登录：guacadmin 密码：guacadmin 我能够设置用户和 rdp 连接。鳄梨酱的用户界面可用 直接通过 docker setup 脚本中配置的映射端口（在我的情况下为 8380），也可以通过根据 guacamoles 手册配置的反向 apache 代理：
<Location /guac/ >
Order allow,deny
Allow from all
ProxyPass http://localhost:8380/guacamole/ flushpackets=on
ProxyPassReverse http://localhost:8380/guacamole/
</Location>
我尝试按照手册进行 rdp 连接 http://guac-dev.org/doc/gug/configuring-guacamole.html#rdp
但是当使用反向代理时，结果是：
这也发生在其他用户身上：
https://sourceforge.net/p/guacamole/discussion/1110834/thread/73abbe35/
如何调试这种情况以找到正确的设置？
自从作为管理员以来似乎有些可疑之处，例如我确实得到了 guacadmin 在以下对话框中尝试启用和保存连接权限时：
我可以访问用于权限的 mysql 数据库，例如 与
mysql> show tables;
