    		 (Required) The API key provided by Centrify.

    Checkout Duration

    Configure the Checkout Duration to exceed the typical duration of your Tenable Nessus Manager scans. If a password from a previous scan is still checked out when a new scan begins, the new scan fails.

    Note: Configure the password change interval in Centrify so that password changes do not disrupt your Tenable Nessus Manager scans. If Centrify changes a password during a scan, the scan fails.
    Use SSL When enabled, Tenable Nessus Manager uses SSL through IIS for secure communications. You must configure SSL through IIS in Centrify before enabling this option.
    Verify SSL When enabled, Tenable Nessus Manager validates the SSL certificate. You must configure SSL through IIS in Centrify before enabling this option.

  2. Once the scan completes, select the completed scan and look for Plugin ID 97993 and the corresponding message - It was possible to log into the remote host via SSH using 'password' authentication. This result validates that authentication was successful.
