Web UI tests now don't require additional configuration to test certificates. Self-signed certificates and CSR are generated on fly. Next variables from ~/.ipa/ui_test.conf for now are deprecated: - arbitrary_cert_path - service_csr_path - user_csr_path Ticket: https://pagure.io/freeipa/issue/7843 Reviewed-By: Sergey Orlov <sorlov@redhat.com>
