I have ArgGIS 10.3.1 Desktop with ArcServer and PostgreSQL 9.3. I have everything configured and talking with one another. I am able to create an enterprise geodatabases through ArcGIS desktop. I have a postgres user, sde user, and another user account. I have imported a shapefile into the enterprise geodatabase through a database setup up with the user account. When I first got everything to work I was able to publish with no issue.
I attempted to register the database with ArcServer utilizing all three accounts setup with no luck. When I attempt to publish the database as a service it indicates that I need to register the database with the server. I have done extensive research with google in order to find a solution, with no luck.
Also, I am self taught on on this so if you are able to keep the response somewhat formatted for the lay folk I would greatly appreciate it.
