Splunk Updated SPLK-1003 Exam Questions and Answers by denny

The failOpen setting in the [duoMFA] stanza determines how Splunk software handles authentication requests when it cannot connect to the Duo Security service. If failOpen is set to True, as in this example, Splunk software allows users to log in without completing a multifactor challenge. If failOpen is set to False, Splunk software denies all logins when it cannot connect to Duo Security. This setting is independent of the authentication type or the secretKey protection. References = Connect to Duo Security for multifactor authentication
