Using SAML 2.0

This authentication mechanism enables you to authenticate via Single Sign-On using SAML 2.0 against supported servers.

To configure SAML 2.0 authentication:

1. To access authentication options, open the ODBC Data Source Administrator where you created the DSN, then select the DSN, and then click Configure.
2. In the Mechanism drop-down list, select SAML_2.0.
3. In the Host field, type the fully qualified domain name of the Impala server host.
4. In the Port field, type the number of the TCP port that the Impala server uses to listen for client connections.
5. Optionally, in the Transport Buffer Size field, type the number of bytes to reserve in memory for buffering unencrypted data from the network.

Note:

In most circumstances, the default value of 1000 bytes is optimal.

6. In the Transport Mode drop-down list, select HTTP.
7. Optionally, click SAML Options and select the Ignore SQL_DRIVER_NOPROMPT check box. When the application is making a SQLDriverConnect call with a SQL_DRIVER_NOPROMPT flag, this option displays the web browser used to complete the browser based authentication flow.
8. Optionally, click SAML Options and select the Enable Auth Cookie Caching check box. When establishing a new connection using SAML SSO authentication, the connector caches the authorization cookie and does not repeatedly open a new browser.
9. Click HTTP Options and in the HTTP Path field, type the partial URL corresponding to the Impala server. For more information, see Configuring HTTP Options.
10. Click SSL Options and select the Enable SSL check box. For more information, see Configuring SSL Verification
11. To save your settings and close the dialog box, click OK.
