Apache requires that be set for most  applications to run properly in an environment like that, so yes, that's the only way for Shibboleth to work since it has to be set regardless. That's a feature (you configure your web server properly and the SP just works). IIS doesn't support virtualization so the SP is forced to compensate, but Apache does so there's no reason to do anything special.

If your application functions without ServerName set, it either never generates self-referential links or it's got a bug.
