To access the database, a user must submit a logon request. The request must specify some or all of the following elements, depending on system configuration and security policy:

  • Authentication mechanism
  • Tdpid
  • Username
  • Password
  • Account string
  • Domain or Realm
Teradata Database may provide some of these elements by default, or transfer them from other sources, depending on the system setup options you have exercised.

When a user submits a logon string, the mechanism (user-specified, or the default) authenticates the user and establishes a session based on user privileges. If the logon is successful, Teradata Database associates the username with a unique session number, under which the session runs until the user logs off.
