Esri_Anonymous is displayed in the attribute field when Editor tracking is enabled

Description

When adding a feature service, published by ArcGIS for Server, to an ArcGIS Online web map for data collectors via the Collector for ArcGIS application in offline mode, 'Esri_Anonymous' is displayed in the attribute field for the last edited user.

Note:
The functionalities of ArcGIS Collector, ArcGIS Explorer, and ArcGIS Tracker are now available in ArcGIS Field Maps. There are no new capabilities planned for these apps—all future updates will be focused on Field Maps. Migration is recommended. See ArcGIS Blog: Migrate to Field Maps for more information.

Cause

Editor tracking in ArcGIS for Server is not designed to transfer ArcGIS Online user account details and can only retrieve ArcGIS for Server user details. This is a known limitation that the system was not designed to accommodate.

Solution or Workaround

• Use a secured feature service: publish a feature service to ArcGIS for Server, and use the built-in security to secure the feature service with the ArcGIS for Server user name and password details. Opening a secured feature service in a web map requires the user name and password to access the feature service and this transfers the secure user details from ArcGIS for Server.
• Use an ArcGIS Online hosted service: publish a hosted feature service to ArcGIS Online and enable Editor tracking. The hosted feature service tracks the ArcGIS Online user, but any edits made are only reflected in ArcGIS Online.
