Maybe it's a browser caching issue - try to load from different PC/Browser or clear browser

Betreff: [Help] Enabling TOTP Plugin with Docker


i have some trouble with enabling the TOTP plugin for a Docker installation. The guacamole
without TOTP extension runs fine. So, after that, i did the following:
- I defined a GUACAMOLE_HOME, say: /config
- I mounted a host folder to /config
- I placed the jar inside the host folder and finally started the container
I can confirm that the container startup script copys the extension from /config to /root/.guacamole
which apparently is the real guacamole home.

After that, i try to access guacamole from my browser and have problems now: After a login,
i only get a message: TOTP.INFO_ENROLL_REQUIRED and a Next-Button. Clicking on the button
spawns a red flash message, saying TOTP.INFO_VERIFICATION_FAILED.

Additional info: I use MySQL as an auth backend, and the user is allowed to set their own
password. The log file has no visible errors, only some "auth successful" messages when i
do the first user/password login step.

For me it seems that guacamole is able to load the extension, but instead of spawning the
QR code and other items, i only get these error messages. I have no idea, why, and am kindly
asking for help because of this.

Thank you very much and best regards,
