We had a request for disabling the “Add User” functionality when the concurrent user limit is reached.
The concurrent users limit is set by Sitecore while granting the license, it can be as low as 2 and the highest I have seen is 100.
Initially we thought of disabling the button from the Kick User page layout then while implementing the changes we did some research and the solution was very simple.
We had to uncheck the “IsVisible” field from the below items in Core DB and you are done:
- AddMoreUsers – /sitecore/client/Applications/LicenseOptions/StartPage/PageSettings/AddMoreUsers
- AddUserBtn – /sitecore/client/Applications/LicenseOptions/StartPage/PageSettings/AddUserBtn

Hope it helps!
Thank you.. Keep Learning.. Keep Sitecoring 🙂
