Hello!
I don't know is it bug or not. But I met the following problem.
I use Guacamole 0.9.11 Incubating and some modified MySQL Authentication
Plugin. My Guacamole account has administrative privileges.
1) I created the new Connection. I filled just the name and saved
Connection and pushed Save button. I didn't fill any connection
credentials to login. And I didn't associate this connection with my
Guacamole user name.
2) I returned to the main Guacamole page.
3) I opened edit page for connection that I created on the first step
and then closed the browser tab with Guacamole UI.
3) I opened new tab with Guacamole UI. My previous session was restored.
4) And then I see the message that Connection Refused.
As I understand Guacamole tries to connect me with Connection that I
created on the first step. But it is impossible because I didn't provide
it with any credentials. More over I didn't associate this connection
with me.
This is part of Tomcat log:
