undertow subsystem authentication configuration ----------------------------------------------- Key: WFLY-3342 URL: https://issues.jboss.org/browse/WFLY-3342 Project: WildFly Issue Type: Bug Components: Web (Undertow) Affects Versions: 8.0.0.Final Reporter: Travis De Silva Assignee: Darran Lofthouse Fix For: 11.0.0.Alpha1 I have a use case where I have static content that I want only authorised web users to be able to access. In the standalone.xml file, I added the following config. <filter-ref name="my-auth"/> under <location> and <basic-auth name="my-auth" security-domain="other"/> under <handlers> But I am getting following error Caused by: java.lang.RuntimeException: JBAS017346: Could not construct handler for class: class io.undertow.security.handlers.AuthenticationCallHandler. with parameters {"security-domain" => "other"} [~ctomc] Mentioned in the forum post that how undertow does authentication has changed significantly and subsystem configuration did not catch up with it properly and request a jira ticket be opened.
