Single sign-on allows users that are logged on to the Kerberos realm to subsequently logon to Teradata Vantage without submitting a Teradata Vantage username and password.

There are two variations of single sign-on, which are based on the authorization method.
If a logon to Teradata Vantage does not include a username and password, the system assumes it is a single sign-on, and defaults to the KRB5 mechanism.
