Change Logout redirect location
Greetings, I am curious if there is a way to change what url the web application directs the user to upon clicking the logout button? We have a custom page as our landing page that has links to the login page for the application as well as a few other places and would like to redirect the user to this page upon loggin out instead of the login page if possible. Thank you.
Password Authentication Custom Password Reset Page
Greetings, I am writing a basic web page to be accessible alongside the current guacamole application that can be used to allow users to reset their passwords. I am writing a custom one as I have custom scripts that need to be ran along with updating data in places outside of the mysql database the application is using for authentication and connection control. I am having a hard time writing the authentication part of the web page as it seems the database stores the hex form of the password hash and the salt. I know the method that is used to create the password hash and store it along with the salt but I can't seem to grab the salt and hash from the database and duplicate the steps in Java in order to see if the provided password they entered is the correct password which is required in order to allow them to reset their password. Any help anyone can provide on how to properly do this in Java would be much appreciated. Thank you
Can you change Database Password Hash
Within the application If you use a database like MySQL for authentication it says that the passwords are salted with a random 32 byte string and then hashed with the SHA-256 hash before being stored. I was wondering if it is possible to change the hashing method to a different hash? Looking into this for reasons related to our current systems and wondering if this is possible.
Custom Application SSH (close window on user logout)
Greetings all, We have a custom built guacamole application with an SSH tunnel that opens within its own window. We would like the window to close when the user types exit to logout of the target machine. I am wondering if anyone can help me understand the best way to do this or point me in the right direction. Thank you
RE: VNC/RDP connection fail (Invalid Credentials?)
We are creating our own custom application as it is site used internally that has other uses but needs to have the VNC/RDP capabilities within the web application. The application makes the connection no problem when we do not send full credentials with the tunnel connection but when we include a password parameter it refuses the connection even when the username and password are correct.

Most code is based off the Skeleton code provided here : Writing your own Guacamole application — Apache Guacamole Manual v1.4.0<https://guacamole.apache.org/doc/gug/writing-you-own-guacamole-app.html> A couple of questions for you: 1) Is there a specific reason you're writing your own web application aside from wanting the users to be able to enter the connection information? If the only reason you're writing a custom app is because you don't want to pre-create all of the connections, in user-mapping.xml, JDBC, or LDAP, then maybe instead of writing an entire separate web application it would be better to just use a difference authentication extension - either use the Quick Connect module, which allows for entering URIs (e.g. vnc://192.168.1.100:5900<http://192.168.1.100:5900>), or write your own module that would allow users to enter that information. 2) Even if you decide to write a custom application, you can test to make sure that the stock Guacamole Client is able to connect and authenticate correctly, which would help you establish where the issue actually is (custom app vs. Guacamole core components). -Nick
