[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot find the user 'AdtServer', because it does not exist or you do not have permission

I was installing SCOM ACS 2012 R2 and configuring it to use SQL authentication. This is not to collect events from an untrusted domain, I was just implementing redundant ACS collectors as described here which would require the collectors to use SQL authentication to connect to the backend database.

ACS setup completed successfully on all ACS collector servers, but the Audit Collection Services shuts down shortly after starting and logs this event

Error occured on database connection:

Status: 0x04080000

ODBC Error: 15151

ODBC State: 42000

Message: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot find the user 'AdtServer', because it does not exist or you do not have permission.

Database: SqlWriter

Connection: Maintenance

Statement:

/**********************************************************

The reason this happened was because I precreated the SQL account and gave it dbcreator role then supplied it to the ACS setup. I then discovered that the ACS installer would actually create the account itself, surprisingly it did not complain that the account already existed and completed successfully but apparently something was still broken.

I uninstalled ACS, deleted the SQL account then reinstalled ACS and now it works.
