https://doc.arcgis.com/en/maps-for-sharepoint/foundation-server/install-and-configure/arcgis-authent...
reads "ArcGIS Maps for SharePoint does not currently support IWA/PKI/LDAP authentication for workflows (ArcGIS Maps Connect and ArcGIS Maps Locate workflows) for ArcGIS Enterprise"
It is not possible to use ArcGIS Maps Locate workflow connected to ArcGIS Enterprise with enterprise logins enabled.
