We have a new corporate Portal (10.3) which is on IIS/Win2008, SSL-only with Windows-Authentication, federated and hosted (with Oracle). Most all the parts are now working, but creating a layer from a CSV file (with X,Y points) is giving strange errors. There is no map-service shown on the Portal contents, but you can see it via the REST end-points. The feature-service shows up on the portal, but is not fully usable. The various log files show errors like 'ERROR: code:403, User does not Permission to access "*.mapserver". Utilities/PrintingTools.GPServer Access is forbidden, regardless of authorization. You can see a similar 403 in the IIS logs, but why? Everything else seems to work.
