The includes section of surefire plugin configuration in testsuite/domain/pom.xml doesn't contain expression to cover DomainClusteredSSOTestCase.
The test is now included in TS run. It's failing with -Dnode0 and -Dnode1 specified but just because of test issue https://bugzilla.redhat.com/show_bug.cgi?id=1110776 which can be warkarounded in jobs.
