Overview
You may notice that a user can't log in to FMB at all, while other users can, even on the same machine. FMB logs may show instances of "The security token could not be authenticated or authorized."
Solution
It is possible that this was caused by the "Remember password" functionality in FMB when logging on to the Oasis platform.
To resolve this issue, delete the following registry key before logging on:
HKEY_CURRENT_USER\Software\Volt Delta\FMB
Additionally, you should check whether the user is actually locked in the Active Directory on the Domain Controller of the hosted platform.
If problems persist, please create a support ticket, providing relevant FMB logs. For details on where to find the FMB logs, please refer to the Locating Agent Workstation Logs article.
