Can't change service properties on federated GIS Server even though I'm an admin
I found a workaround for the problem... the main problem of the message was that the item doe not exist in portal, and the service in ags was referencing a item. For some reason the items were not created in portal when federated. So, the first thing I tried was to follow this guide: http://enterprise.arcgis.com/en/portal/latest/administer/linux/importing-services-from-a-federated-s...
But, it not worked for me 
, maybe it works for some of you.
So, I went to edit the item in ArcGIS Server Administrator Directory:
and deleted the highlighted and save, this created as magic the item in portal:
{

"type": "GeometryServer",
