Sometimes a User no longer wants or needs to access Intelligentcontract. You are not able to delete a user record - this is because their User records are still required for auditing purposes.  However you can remove an intelligentcontract licence , the disables their access to the account and frees up the licence to be used by someone else. This article explains how to complete this common task. 

Users can be "unseated", unseating a User removes their licence which means they are no longer able to login.  That licence is now becomes available to allocate to another User. To unseat a user you must be a User with Admin rights. 

Navigate to Configuration > Users and Permissions > Users

Find the required User and edit the "Assign Licence" field, uncheck the box and [Save], this Users licence is now free and they will no longer be able to login.
