To validate users, TDP performs the following steps:
- 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. - 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.
