When using the auto provisioning process, data for attribute fields are passed for new user accounts and existing user accounts. Our goal is to create a process for auto-registration. If a person does not have an account and attempts to access Workfront, a basic "request access level" user is created. However, the "home group" field is required. I would like to have the "home group" field only updated for new users. Since we attempted to use a default value for the home group for new users, applying it to existing users can break reports and structures throughout the system. This functionality is preventing us from using the auto provisioning process.
