In Setup, System, Single Sign-On (SSO), there is a section named "Map User Attributes". I want to map SAML 2.0 assertion attributes to Workfront custom form attributes, but cannot. The "Map User Attributes" only lets you map SAML assertion attribute values to specific built-in Workfront fields, as defined here: https://support.workfront.com/hc/en-us/articles/217194907-Configuring-Workfront-with-SAML-2-0. This causes issues for us as we leverage a custom form for Vantage information integration and cannot write values to the fields on this custom form when the user logs in via SSO.
