I haven't been able to find anything on this sort of issue, so I'm asking. What I'm attempting to do is allow the use of the proxy to access the secured services of an application. This part already works fine, of course. I'm curious on if I can use IdentityManager to just secure the editable part of a feature layer thats not attached to a web map? So in essence we'd be hitting a secured editable service on the arcgis server (not AGOL) and then have it prompt to login to allow them to edit. Is this just as easy as setting the owner of the layer to a specific user in portal and whenever that layer is accessed, they'll be prompted? Or is there a lot more to it? Thanks!
