CIFS was removed from CI as port mapping issues were detected in the TestContainers setup (port bindings on testcontainers are not mapped 1:1 and have to be fetched at runtime). At the same time, CIFS backed does not support specifying a different port other than the standard 139 and 445 determined by transport option, either NetBiosOverTCP or DirectTCPTransport).
