After being authenticated by the directory, directory-based users are authorized database access privileges according to the following rules:
| Directory Maps Username to Database Objects | Directory Username Matches Database Username | User Privileges |
|---|---|---|
| Yes | N.A. | Privileges of objects to which username is mapped. |
| No | Yes | Privileges of matching database username. |
| No | No | No database access privileges. |
One or more setup tasks (depending on implementation) must be completed before a directory user can access the database. See Teradata Vantage™ - Analytics Database Security Administration, B035-1100.
