(Optional) Enable providing an authentication context class for SAML

You can enable the instance to send an authentication context class request to the IdP containing your instance's preferred authentication request format.

About this task

If you enable creating an AuthContextClass message, then you must also specify an authentication context class reference format.

Note:

Some IdP's do not allow the Service Provider to set the authentication context class. Disabling this setting allows the IdP to choose the authentication context class.

Procedure

1. From the property Create an AuthnContextClass request in the AuthnRequest statement, select Yes to specify a particular context class such as Password Protected Transport, or select No to have the IdP select the most appropriate context class.
2. If you selected Yes to Create an AuthnContextClass request in the AuthnRequest statement, then in The AuthnContextClassRef method that we will request in our SAML 2.0 AuthnRequest to the Identity Provider property, enter the URN of the context class you want to use for authentication (see table).

   Table 1. AuthnContextClass URN options

   Authentication type	Authentication context class URN
   Forms-based authentication	urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport
   Kerberos-based authentication	urn:federation:authentication:windows

   By default, the integration uses a Password Protected Transport authentication method.
