![]() The Scoping element, which includes a list of identity providers, is optional in AuthnRequest elements sent to Microsoft Entra ID. Microsoft Entra ID supports AuthnContextClassRef values such as urn:oasis:names:tc:SAML:2.0:ac:classes:Password. It is optional in AuthnRequest elements sent to Microsoft Entra ID. The RequestedAuthnContext element specifies the desired authentication methods. Microsoft Entra ID ignores the AllowCreate attribute. If SPNameQualifier is specified, Microsoft Entra ID will include the same SPNameQualifier in the response. This means that the value is temporary and cannot be used to identify the authenticating user. urn:oasis:names:tc:SAML:2.0:nameid-format:transient: Microsoft Entra ID issues the NameID claim as a randomly generated value that is unique to the current SSO operation.Microsoft Entra ID issues the NameID claim as a pairwise identifier. urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified: This value permits Microsoft Entra ID to select the claim format.urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress: Microsoft Entra ID issues the NameID claim in e-mail address format.urn:oasis:names:tc:SAML:2.0:nameid-format:persistent: Microsoft Entra ID issues the NameID claim as a pairwise identifier. ![]() The Format attribute can have only one of the following values any other value results in an error. If NameIDPolicy is provided, you can include its optional Format attribute. ![]() This element requests a particular name ID format in the response and is optional in AuthnRequest elements sent to Microsoft Entra ID.Ī NameIdPolicy element looks like the following sample: Typically, this is set to the App ID URI that is specified during application registration.Ī SAML excerpt containing the Issuer element looks like the following sample: The Issuer element in an AuthnRequest must exactly match one of the ServicePrincipalNames in the cloud service in Microsoft Entra ID. Microsoft Entra ID also ignores the Conditions element in AuthnRequest. If this is true, Microsoft Entra ID will attempt to authenticate the user using the session cookie.Īll other AuthnRequest attributes, such as Consent, Destination, AssertionConsumerServiceIndex, AttributeConsumerServiceIndex, and ProviderName are ignored. This is a boolean value that specifies whether Microsoft Entra ID should authenticate the user silently, without user interaction, using the session cookie if one exists. If true, it means that the user will be forced to re-authenticate, even if they have a valid session with Microsoft Entra ID. If provided, this parameter must match the RedirectUri of the cloud service in Microsoft Entra ID. Microsoft Entra ID expects a DateTime value of this type, but doesn't evaluate or use the value. This is a DateTime string with a UTC value and round-trip format ("o"). ![]() ID must not begin with a number, so a common strategy is to prepend a string like "ID" to the string representation of a GUID. Microsoft Entra ID uses this attribute to populate the InResponseTo attribute of the returned response. A sample SAML 2.0 AuthnRequest could look like the following example: To request a user authentication, cloud services send an AuthnRequest element to Microsoft Entra ID.
