[keycloak-user] Non-standard SAML profiles

Hello all I am looking at how to support SAML profiles beyond the usual Web SSO profiles that are typically supported within Identity Broker products such as KeyCloak. The biggest two in my mind are eIDAS which is an EU regulation and technical standards for cross-border Identity, plus the UK Government's GOV.UK Verify service The SAML specifications and profiles are available at: https://joinup.ec.europa.eu/sites/default/files/eidas_message_format_v1.0... https://www.gov.uk/government/uploads/system/uploads/attachment_data/file... (short SAML snippet at: https://alphagov.github.io/rp-onboarding-tech-docs/pages/saml/samlIntegra...) I guess the short version is that I suspect I need to work on extending the SAML Profiles that KeyCloak supports, but there is not yet an 'adapter' to start with? Any pointers, or work that is already looking at how to plugin further SAML Profiles into the product gratefully received! Regards, Simon
