The Identity tab is used to set the user identity for all components running in a given package. The default value is Interactive User, which is the user who logged on to the Windows NT server account. If you want to select another user, you can select the This user option and specify an account name and password.
Important If you specify another user and password, Microsoft Transaction Server does not validate the password when it is specified. Running a package with an invalid password results in a run-time error and a message in the event log.
To set the This user option to a user or group, you must be logged on to the computer that either maps to that user or is included in the specified group.
