             Summary: Authentication based on certificates does not work in Elytron with Undertow
                 Key: WFLY-7687
                 URL: https://issues.jboss.org/browse/WFLY-7687
             Project: WildFly
          Issue Type: Bug
          Components: Security
            Reporter: Jan Tymel
            Assignee: Darran Lofthouse
            Priority: Critical


It is not possible to set up authentication based on certificates. I followed the community documentation [1,2] to set up 2-way SSL for apps and certificates based auth. Everything worked as expected until I tried to deploy an app. I got this output

This might be caused by different representation of {{CLIENT-CERT}} attribute within Elytron and Undertow. It appears that Elytron uses {{CLIENT-CERT}} [3] whereas Undertow uses {{CLIENT_CERT}} [4]
