Our usernames are look like ‘username’@example.com<http://example.com>. In our other authentication system we append the domain to whatever the user enters in for look up in AD and we were wondering if there was a setting in Keycloak that allowed this functionality. _______________________________________________ keycloak-user mailing list keycloak-user@lists.jboss.org<mailto:keycloak-user@lists.jboss.org> https://lists.jboss.org/mailman/listinfo/keycloak-user
