```` Element =========================== This is an **optional** child element of the :doc:`sustainsys.saml2 ` element. Enables overrides of default behaviour to increase compatibility with identity providers. Attributes ---------- ``unpackEntitiesDescriptorInIdentityProviderMetadata`` (Optional) If an ``EntitiesDescriptor`` element is found when loading metadata for an IdentityProvider, automatically check inside it if there is a single ``EntityDescriptor`` and in that case use it. ``IgnoreAuthenticationContextInResponse`` Do not read the ``AuthnContext`` element in Saml2Response. If you do not need these values to be present as claims in the generated identity, using this option can prevent XML format errors (``System.Xml.XmlException: ID0013: The value must be an absolute URI``), when value cannot parse as absolute URI.
