I have an existing instance of ColdFusion 11 server and SQL Server 2012 on a Windows 7 Ultimate platform.
I have several SQL Server datasources already connected successfully connected using: localhost\SQLEXPRESS, username "sa" and my password. When I try to add a new database in the CF Administrator I get this error:
Connection verification failed for data source: ocm5 java.sql.SQLInvalidAuthorizationSpecException: [Macromedia][SQLServer JDBC Driver][SQLServer]Login failed for user 'sa'. The root cause was that: java.sql.SQLInvalidAuthorizationSpecException: [Macromedia][SQLServer JDBC Driver][SQLServer]Login failed for user 'sa'.
It appears to be a login issue, not a connection issue so I don't think it has to do with source limits on Developer platforms.
