How to check the permitted user count of the Infoworks ADE Web UI and the permitted Cluster size?
As an Infoworks Admin user, please check the Admin > License Manager section for the features enabled:
Infoworks checks only the Active user count. So, if the Users count reaches the threshold value and if you want to add more users, please disable the login for the users who are not active and then add the new users.
Go to Admin> Users tab and select the user that you want to disable and click on the Disable Login option under "Update access control" for the User.
