In My ESRI portal, Under 10.5.1 product authorizations tab. I am can to see only "ArcGIS Server" and "Level 2 Named user" authorization file and there is no separate authorization number for Portal for ArcGIS for 10.5.1.
Sorry. Just re-read your email. In the installation we just did we had to get a provisioning file for Portal and a separate provisioning file for ArcGIS Server. ArcGIS Server is provisioned based on Server extensions. For example, to use Image Server there is a specific provisioning file for it and another just for ArcGIS Server base install. The provisioning file for ArcGIS Portal will have a certain number of Level 2 and Level 1 licenses based on your agreement and licensing you have with ESRI.
You need a separate authorization.
Thanks Bill Harvey.
