User Validation - Teradata Director Program

To validate users, TDP performs the following steps:

1. Determines if the user entry is a valid TDP command.

   IF the command is . . .	THEN TDP . . .
   not a valid TDP command	returns the standard syntax error message to the source virtual machine or user.
   a valid TDP command	validates the authority of the userid to issue that specific command.

2. Verifies if a user is authorized to issue a specific command by searching for a matching userid listing in an existing internal table.

   IF the userid is . . .	THEN TDP . . .
   listed in the table	confirms that the user is authorized to issue the command.
   not listed in the table	reverts to a “default authority” to determine whether the userid is valid, and if so, if such a user is authorized to issue the command. The TDP command is then accepted and processed, or rejected with an error message, based on this default validation process.
