[keycloak-user] X509 Direct Grant with client certificate

Hi, Is it possible to pass the same client certificate in a token request with different login credentials? My current setup doesn't seem to allow this and I can't find any documentation saying this is not possible I have configured an X509 Direct grant flow using X509/Validate Username(X.509 Config) This is configured to take the Subjects Common Name, with the attribute "NAME" I have configured a trust store with 1 certificate (want to share this across users) When I add the Subject Common Name to user 1's attribute, they then require the key pair to generate a token, however once I share the same attribute details to user 2, both user 1 and 2 stop working. Maybe I am missing some configuration that will allow my users to share the same certificate I ideally do not want to have one certificate per user as this will get out of hand to manage, as the population of the realm increases Kind Regards, Chirag Unnadkat Business Analyst Cerillion plc E. chirag.unnadkat@cerillion.com<mailto:chirag.unnadkat@cerillion.com> T. 0207 9276029 W. www.cerillion.com<http://www.cerillion.com/> Addr. 25 Bedford Street, London, WC2E 9ES, UK ________________________________ Cerillion Technologies Limited is a limited liability company registered in England No. 3849601 with Registered Office at 25 Bedford Street, London WC2E 9ES.
