We have received the request to provide a SAML token instead since a SAML token needs to be provided for each subsequent SharePoint request. Is this possible in IdentityServer or does that require some sort of custom code (e.g. custom grant type?) and if so, where to start? Or are SAML tokens only available through the WsFed/ADFS side of IdentityServer?"}}
