Use Only SSPI

Key Name	Default Value	Required
UseOnlySSPI	Clear (0)0	No

Description

This option specifies how the connector handles Kerberos authentication: either with the SSPI plugin or with MIT Kerberos.

• Enable For This DSN (1 in the DSN entry in the registry): The connector handles Kerberos authentication in the DSN connection by using the SSPI plugin instead of MIT Kerberos by default.
• Enable For DSN-less Connections (1 in the connector configuration section of the registry): The connector handles Kerberos authentication in DSN-less connections by using the SSPI plugin instead of MIT Kerberos by default.

If you want all connections that use the Simba Impala ODBC Driver to use the SSPI plugin by default, then enable Use Only SSPI for both DSN and DSN-less connections.

• Disabled (0): The connector uses MIT Kerberos to handle Kerberos authentication, and only uses the SSPI plugin if the GSSAPI library is not available.
