Using SharePoint Designer 2013 I am attempting to setup an External Content Type to a SQL DB. I have setup the SQL database with a valid login that was also used to setup an account with the Secure Store Service. I am running SharePoint 2013 designer and have opened my site with administrative credentials. No matter what, I continue to get the "access denied" message when I try to add this SQL database to my ECT section in SPD. All users have access to invoke the BCS app.
I have deleted and recreated the BCS service application and it is running with farm credentials and temporarily I added the farm account to the local admin account....and again verified that all users have rights to run BCS...
In all other aspects my SharePoint sites are working, I can modify and add via SPD and publish...etc...but I cannot add a connection to an external SQL server. I have also verified through Excel that I can connect to my SQL DB with the same credentials that I am trying in SharePoint and everything works.
Most of the posts I see in this area relate to permissions or access problems AFTER the ECT connection is created. My problem is I can't even get a connection created.
