Support for protocol is not installed
Hello,
I'm trying to get Guacamole server 1.5.2 running without success, that's the reason why I subscribed to this mailing list after querying some search engines without luck.
Here's the steps I successfully did so far:
1. Compile `guacd`, with all the statuses set to 1 except for `wsock32`
2. Running `guacd`
3. Testing from a remote machine `telnet <server> 4822`
4. Creating 3 user-mapping (user-mapping.xml) for my own user: 1 for vnc, 1 for ssh, 1 for rdp
5. I can see those mappings when I connect to the web interface at http://nixos.lan:8080/guacamole/
What's not working is when I hit one of the 3 mappings I've created, in the logs I have:
```

Do you know what could prevent the creation of a WebSocket tunnel to guacd ?
Thanks in advance.

Thanks for following up, it's always useful to know the 'fix'.

Thanks,
The issue has been fixed. The issue was not from `ldconfig` or anything like that but merely by a wrong assumption I was doing about Guacamole.
I was thinking from the beginning that Guacamole could run a RDP server by itself... but I was wrong.
After running XRDP locally, I was able to connect successfully ;)
Thank you for your help on this!

The web application is definitely connecting successfully to guacd (you
would not see any "Support for protocol ... is not installed" messages
otherwise).
The error you're seeing in the Guacamole logs could easily be caused by
the protocol support being effectively missing (perhaps due to your
system's linker cache not being updated after building by ldconfig).
