What Happens When a New User Is Created via SAML
A new user created via SAML is a Regular User and is automatically added to the Default Group and assigned an empty Favorite Folder named My Favorites.
A default user type is configured by the SAML_AUTOCREATE_USERTYPE variable. Its default value is R which stands for Regular User, the two other available options are: P - Power User, A - Admin.
