Deploying MIM 2016 - no MIMMA account was created in SQL and initial Create MA failes

I have followed TechNet Deploy MIM and have been successful with the initial build. I installed the MIM 2016 Synchronization Service , the MIM Service & Portal and attempted to Create the MIM MA for the FIM Management Service Agent.   I get errors "Failed to connect to the specified database".  The document states to use the contoso\MIMMA account I created at the beginning of the build along with other service accounts and groups.

I checked the SQL 2014 Standard instance on the same server.  It only has two accounts provisioned for MIM (MIMService & MIMSync)

What MIM accounts are required to have logins & roles in SQL?

Is MIMMA the correct account to use for this function?

Thanks, Stu
