What is an anonymous user?
If you do not have sufficient access to see the name of a user, the SDL Studio GroupShare can display the user as Anonymous User.
For example, if you have read permission to an organization but not read access to a user who holds a role in the organization, SDL Studio GroupShare will show the roles but display the holder of the roles as Anonymous user.
To see the user's name, you need View User permission in the organization that stores that user details (the user's home organization).
When working in an assignment workflow, GroupShare displays the other users assigned to work on the same files as you as Anonymous if you do not have View Other Users permission.
