I've inherited a SQL Server Web Edition RDS instance from another firm whereby they took a snapshot and then shared it with our firm's RDS account.

After reinstating the instance under our account, I wanted to set up native backups but ran in to permissions issues when running the msdb.dbo.rds_backup_database command:

The EXECUTE permission was denied on the object 'rds_backup_database', database 'msdb', schema 'dbo'.

Believing this was due to permissions issues on the account that was given to me, I reset the used the "New master password" functionality within the RDS console to reset the master password. After I was notified that succeeded, I attempted to login but got a login failed error.

In looking at the results from the following query, select * from master.sys.server_principals I can see that the master login is disabled.

When running the following query,

select suser_sname(owner_sid) as 'Owner', state_desc, *
from sys.databases

I can see that all the databases were created with the master account.

How would I enable the master user's login in this case or does anyone know of a workaround?



  • Have you tried using the new-master-password in RDS again? – Brent Ozar Jun 11 '18 at 19:24
  • Yes but I get a login failed message and in the RDS error log window I see the following error, "An error occurred while evaluating the password.", which I believe is because the account is disabled. – Ben Jun 11 '18 at 19:37
