In this Tutorial we show you how to solve the issue with the Kopano WebApp Login using the Mozilla Firefox Browser under Windows.

Kopano WebApp did not match session

Symptom

If you try to Login via the Kopano WebApp 3.5.2 from Mozilla Firefox 95 under Windows, an animation with rotating circle appears after entering user and password, the circle continues to rotate non-stop, the page stops and it doesn’t go any further, after pressing the F5key or Ctrl+R (Refresh) authentication resume successfully.

Cause

The browser performs a Javascript function that sends a fingerprint (special ID) to the server (at the login request) and later when logging in, the server checks the fingerprint for compliance. Mozilla Firefox (version 94.0.2 / 95.02 64bit) distinguishes the second fingerprint from the first. With Firefox on Linux, the behavior was not detected and does not seem to be known.

Solution

The workaround/solution is to remove the Arial Narrow font from Javascript, so that the fingerprint does not change. To do this, edit the Java file fingerprint.js.

$ nano /usr/share/kopano-webapp/client/fingerprint.js

Delete the text Arial Narrow; (marked in red) (Arial Black; Bodoni MT).

Javascript fingerprint.js

After removing “Arial Narrow” from Javascript, the session fingerprint is no longer changed, the login passed successful.

Try now Kopano WebApp Login

This app contains the Kopano WebApp, which users can use to conveniently carry out their everyday communication and organizational tasks, from e-mail and calendar entries to file management and video calls. The WebApp can be expanded with plugins and used with various themes that can also be customized.

To install Kopano WebApp, the Kopano Core App must already be installed on at least one server. The Kopano WebApp does not necessarily have to be installed on the same machine. It can also be installed on several servers at the same time for load balancing or for optimized data communication. This app is also required if the Kopano DeskApp is to be used.

Outlook do not accept my password

If Outlook do not accept your password and you know you’re using the password for your email account, you might have an email account that requires additional security.

Gmail, Yahoo, iCloud, Outlook.com, and AOL accounts all use two-factor authentication to help verify that you’re the person trying to access your email account.

To add your email account to Outlook, depending on your provider you might need an app password, also known as an application password. This is a different password than your regular email account password. One way you’ll know you need an app password is if you see the following message: 2-factor authentication is set up for your account. Please sign in using your application password.
