Is there a way to filter/avoid duplicate attribute names in keycloak SAML assertions?
I'm trying to setup SSO with nextcloud (13.0.4) and keycloak (4.0.0.Final) (as SSO/SAML IDP und user management solution) like described at SSO with SAML, Keycloak and Nextcloud . However, trying to login to nextcloud with the SSO test user configured in keycloak, nextcloud complaints with the following error: OneLogin_Saml2_ValidationError: Found an Attribute element with duplicated Name /var/www/html/nextcloud/custom_apps/user_saml/3rdparty/vendor/onelogin/php-saml/lib/Saml2/Auth.php - line 177: OneLogin_Saml2_Response->getAttributes() /var/www/html/nextcloud/custom_apps/user_saml/lib
