The tdtrusted group is created automatically at installation of Teradata Database. Tdtrusted access allows nearly all command-line monitoring and administration of Teradata. The advantages of using tdtrusted include greater security because root access is limited and greater accountability because administrative user actions are recorded under each account rather than as the root user.

Non-root accounts that administer Teradata must be members of the tdtrusted group on all Teradata Database nodes. Each customer site should determine how to implement this within site-specific account management policies. Tdtrusted logons rely on standard UNIX account management facilities.
