Subject RE: RDP
Date Tue, 30 Apr 2019 22:19:52 GMT
Hello Mike:

So I created a local user called guacamole-post on the Windows system. I set the password
to Pa$$word1234. In remote settings >Remote Desktop, I have allow remote connections to
this computer checked. I have NLA unchecked. Under select users, I have the user guacamole-post
added.

In Guacamole, I have a connection for the machine. The only settings which are not blank:
Protocol: RDP, Hostname: 10.17.102.93, Port:3389, Authentication: guacamole-post, Password:
Pa$$word1234. Security mode: TLS encryption, Ignore Server Certificate: {checked}, keyboard
layout: US English (Querty), Color depth: Low color (16-bit).

When I try to connect:

I've also tried creating a user called guacamole-post, and giving it access to that connection
- I get the same exact message, except the last line reads:

Hello Mike:

With NLA disabled, Windows still isn't prompting...

Hello Mike:
So my boss, who is familiar with Guacamole looked at it - he said if you leave the username
and password fields blank, it is supposed to prompt you when you try to connect

No, your boss is incorrect. Guacamole does not prompt for credentials with the exception of
its own authentication.

*Windows* will prompt for credentials, but only if it is not configured to require NLA. Windows
will not prompt if NLA is in use.

You need to pre-configure the connection credentials or pass them through.

Also in Guac, VNC also isn't asking for a password if you leave the field blank.

Guac will not do this. You need to pre-configure the connection credentials or pass them through.
