If you are seeing a warning message "Service user {username} cannot be created, maximum number of users for this plan exceeded" when adding new service users, that means that you have exceeded the current limit of 50 users per service.

This limit can be increased by contacting our support channel. When doing so, please give the support team the project name, as this service user limit is applied on a project level, meaning that all services under a project will have this new limit. For Kafka specifically, do be careful when increasing the user limit as applying very large ACLs comes with a performance cost.
