No client license available message when logging in.
If this message comes up and login anyways you'll notice that you can only see the reporting and settings section, like below:
When all client licenses are taken up, PassagePoint features a freebie 'admin' license that allows 1 super admin to login which then allows entry into the configuration and reporting section. The idea is to allow a single admin into the application to do settings change and/or reporting without incurring a client license charge.
If you don't believe you've not exceeded the client license, review the client licenses against the active workstations
1) review licenses
Home > configure system > product licenses > take a count
2) Review the Active users report and take a count of the active users. If your user count is at or above your client license, you have exceeded your license count.
