How do you record users in edit tracking fields (created by & edited by) when using arcgis collector?
We have feature service published via our on premise arcgis server and served through an arcgis online map in offline mode, we have 6 field operatives using collector logged in as arcgis online users everything works well except all records get recorded as 'Esri_Anonymous' as the created by & edited by instead of the actual user that submitted the record.
ArcGIS Server and Desktop versions used 10.3, latest version of iOS collector.
Any ideas what I have missed in configuration.
