Data you can view

The SAML audit log provides the following information:

Data type	Description
Event description	The details of the event described in the Event name field
Event name	Two types of events are logged: Successful logins and failed login attempts
User	The email address or name of the user who triggered the event
Application name	The SAML application that initiated the event
Organization name	The user's organization
Initiated by	The provider who initiated the event. Can be the identity provider or the service provider.
Failure type	For failed login attempts, a failure type is displayed. Go to Failure types below for details.
Response status/ second level status	Status information about the success or failure of the SAML request. For details on status codes, go to SAML v2.0 Core, Section 3.2.2.2.
IP address	The internet protocol (IP) address used by the user to sign in to the SAML application. This might reflect the user's physical location, but not necessarily. For example, it could instead be a proxy server or a virtual private network (VPN) address.
Date	The date and time the event occurred (displayed in your browser's default time zone)

Failure types and solutions

The following failure types are recorded in the audit log:

Failure type	Solution
Application not configured	Verify that the service provider settings (including the Entity ID) are configured correctly in the Admin console
Application not enabled for user	In the User access section of the the app's settings page in Admin console, verify that the application is ON for the organization that contains the user
Invalid name ID mapping	There is a mismatch between the NAMEID parameter in the application and the one configured in the app's settings in the Admin console. Check that the schema still exists and reconfigure the NAMEID mapping for the application.
Name ID mapping unavailable	The mapped attribute for NAMEID mapping could not be found. As administrator, check that the schema still exists and reconfigure the NAMEID mapping for the application.
Invalid service provider ID	Check that the configuration on the service provider side matches the app-id field configured in Admin console. Ensure that the SP ID being passed in the request URL is the same as the app-id.
Bad request	The request was malformed, or the ACS URL in the request does not match the one configured in Admin console. Check that the ACS URL configured for the service provider is correct.
Passive authentication failed	The user could not be logged into the identity provider (IdP). Sign back in to the IdP from your browser.
User is unauthorized	Verify that the application is ON for the organization or group that contains the user
Unknown	Login failed for an unknown reason
