How many SSL certificates does ArcGIS Server need?

Question

Hi, I would appreciate if somebody could clarify how many SSL certificates I need in the following setup.

Windows server with IIS7+ with ArcGIS for Server 10.2.2 and WebAdaptor configured.

Do I understand correctly that the certificate used for IIS has nothing to do with the certificate for ArcGIS Server? Therefore, I need one CA-signed certificate for ArcGIS Server and if I am going to host some secure web application on the same machine I need another CA-signed certificate for IIS right? The ArcGIS Server services should be available to client applications hosted on other servers too and therefore both my certificates need to be CA-signed. WebAdaptor does not need any certificate.

Is that correct?

Filip.

If the message given by your map is similar to this:

Yo need to change the share property of your map to public.

I believe that we are having the same issue.  We just recently upgraded to ArcGIS server 10.5.1 along with WebPortal and Portal for Server.  We have our map created that we want to share but when I try to share the map or use the link on any workstation it's asking for a username and password.  We were told to contact our IT department for help with a certificate to access the server and share the map to the public world.  I'd like to think this is pretty much the same issue as above.

I *absolutely* know it will work - I only suggested deploying apps on the same web server instance to save a little money on the certificates.

You'd want a certificate for that application server so that you don't get mixed content messages in the browser, but as long as the solution uses SSL all the way through from end to end, you'll be golden.
