When performing SSO, ODBC Driver for Teradata performs reverse DNS lookup and must succeed. The reverse lookup result must be the FQDN of the database node.
Third-Party Sign-Ons are not supported.
There are two SSO scenarios:
- Direct Sign-On: If SSO is enabled and if username and password are not specified in the ODBC Connection APIs (SQLConnect, SQLBrowseConnect, SQLDriverConnect), then a Direct Sign-On is considered.
- Third-Party Sign-On: If SSO is enabled and if username and password are specified in the ODBC Connection APIs (SQLConnect, SQLBrowseConnect, SQLDriverConnect), then a Third-Party Sign-On is considered.
