When attempting to login to P6 Professional, using the Cloud Connect driver and "Enable Client-side Cache" is enabled in the database configuration, the connection reports as successful, however the following error is observed:


Invalid username or password


Clearing the "Enable Client-side Cache" option immediately resolves the issue.
