[satosa-users] SAML2 frontend NameID format unspecified (or email)

Hi, I have a SATOSA use case where the SAML SP that is receiving the assertion from the SATOSA IdP needs to consume a NameID with format urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified with a particular (non-standard) value. Has anyone done this with SATOSA? If so, my questions are: 1) What is required for the SAML2 frontend configuration? 2) What is required for the metadata of the consuming SP? 3) What do I need to do, say in a microservice, to populate the value? If the 'unspecified' format is not possible, I might also be able to leverage the format urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress Has anyone used that format for the NameID asserted to the consuming SP? Thanks, Scott
