The instructions for defining the connection profile to EG users is in this doc.

 

More about IWA and SPNs is in this admin doc.  Pay special attention to the requirement for "Trust for Delegation", necessary for the user auth to make the additional network hop from SAS to SQL Server.  Details on how to do that are here (same doc, different topic).

Logon to your server and open Task Manager. Open the Details tab and look for OBJSPAWN.EXE. Under the User Name column it will either say SYSTEM or the actual account the service is run under.

 

Regarding SPNs, I'll leave that up to more knowledgeable contributors.

Got it. Thanks @SASKiwi. Do you have any idea how to register custom SPN's for SQL server service account?

We are trying to use IWA while connecting to SQL databases from SAS EG.

As far as I'm aware you don't need SPNs.  To connect from SAS to SQL Server we just specify IWA in the database connection string like so:

 

proc sql;
 connect to odbc (noprompt = "server=MyServerName;DRIVER=SQL Server;Trusted Connection=yes;");
  create table Want  as 
  select * from connection to odbc
  (---- Put your SQL Server query here
   )
  ;
  disconnect from odbc;
quit;

As long as you log on to SAS with the service account then the  - Trusted Connection=yes - option does the authentication with the database.

 

If you talking about EG connections to SAS using IWA then indeed SPNs may be involved as @ChrisHemedinger describes.
