constraint drive authentication method in undertow doesn't work with elytron ---------------------------------------------------------------------------- Key: ELYWEB-8 URL: https://issues.jboss.org/browse/ELYWEB-8 Project: Elytron Web Issue Type: Bug Reporter: Darran Lofthouse Assignee: Bartosz Spyrko-Śmietanko Priority: Critical When elytron is enabled constraint driven authentication method (i.e. proactive-authentication=false) has no effect. If you try to request an unsecured page sending in an invalid user with basic authentication, you should get the page returned with constraint drive authentication and a 401 with proactive authentication. This is what happens without Elytron enabled. But if you enable Elytron it gives a 401 in both cases.
