---------------------------------------
Summary: User session locked in use and cannot reset?
Key: GUACAMOLE-1232
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1232
Project: Guacamole
Issue Type: Bug
Components: guacamole, guacamole-client, guacamole-server, RDP
Affects Versions: 1.2.0
Environment: Ubuntu 20.04 guacamole server, clients range from Windows
10 and Windows Server 2016
Reporter: Joseph Gullo
An RDP session is locked, when I try to connect I get the following message:
The Guacamole server is denying access to this connection because you have
exhausted the limit for simultaneous connection use by an individual user.
Please close one or more connections and try again.
I have logged out of that computer, I have restarted that computer. It is a
Windows 10 computer. My user is able to connect to other computers (Windows 10
and Windows Server 2016) using the same guacamole session. From the other
computers, I am able to successfully RDP into the original problematic
computer. From a different (admin) user account I get the same message trying
to log into the problematic computer. I logged out of guacamole completely and
logged back in, same message. I closed the chrome session entirely, upon
trying again, same message. I closed chrome completely, opened an incognito
tab, same message.
I have restarted guacd AND rebooted the guacamole server. I have edited the
session for this computer to allow "Maximum Number of Connections" to be 5 and
"Maximum Number of connections per user" to be 5. From my admin user I have
been able to kill the user session of the problematic user/computer (or,
confirm it isn't there) and when I re-start the whole process I get the same
connection error.
The windows system logs show no errors, but I do believe I am seeing a
successful authentication attempt.
Somehow, this RDP session is locked and I can't unlock it; my worry is there is
some database artifact triggering guacd to think the session is alive when it
isn't.
The logs in catalina.out show the following:
