In a new installation of SQL Server 2012 Standard, we have mixed-mode authentication enabled. Using Windows authentication, I can authenticate and use SQL Management Studio as expected. Using SQL authentication, SQL Management Studio will not let me authenticate. Two strange symptoms:
- Typing in the password field on the SQL Management Studio 'Connect To Server' dialog has a long lag of about 3 seconds per character typed
- Authentication fails, even though the password is entered correctly
I am certain that we are using the correct password, and we can authenticate successfully using the same SQL credentials from other applications. I have tried switching network protocols, using server aliases, but the problem appears to be in SQL Management Studio.
