I used Administration>Add User in ArcCatalog 10.5.1 using a sa connection to an enterprise database based on Windows, ArcServer 10.3.1, SQL Server 2016 RC3 to add a user named "temp" for a demonstration. Now I want to delete user "temp", but I can't figure out how. I tried with SSMS, but it reported it was unable, that there was also a schema named "temp". Was "temp" an unfortunate name choice, or do I want to also delete this schema?
All I could find was this suggestion for a Drop tool. Drop Database User tool
