After a worker is created, you can't update or delete the user information or roles though the worker service. Make updates though the User service

HDL Error: After a worker is created, you can't update or delete the user information or roles though                       the worker service. Make updates though the User service

If you have already loaded the worker you can not use Worker.dat file to load User Information. Worker.dat file can only be used at the time of new worker creation, if the worker already exists in the system then you need to use User.dat file to add/remove roles or to update the user account information.

In the User.dat file, discriminator User accepts only one role per user at a time. If you want to add multiple roles for a user at the same time, please use UserRole discriminator.
