You know when you are on a tight schedule, the stupidity that comes with MS SQL, ColdFusion and a Windows Server can make you go bald. There is no reason for something as simple as creating a datasource to be throwing dumb error messages!
Connection verification failed for data source: foo
java.sql.SQLException: [Macromedia][SQLServer JDBC Driver][SQLServer]Login failed for user ‘foouser’. Reason: The password of the account must be changed.
The root cause was that: java.sql.SQLException: [Macromedia][SQLServer JDBC Driver][SQLServer]Login failed for user ‘foouser’. Reason: The password of the account must be changed.
The password has been changed half a dozen times!
Update: Ah! Either 1) Know what your password policy is and make sure your password is compliant or 2) turn off “Enforce password policy” and “User must change password at next login” (which was my problem). For a datasource, you can probably remove the check from “Enforce password expiration” as well. Note that if you try to do all three of these at once that you will get errors. Remove “User must change password at next login” first then “Enforce password expiration” then “Enforce password policy”.
