Enforce ``saml2`` protocol in Apache config
Enforce ``saml2`` protocol in Apache config

Shibboleth, a SAML2 federation software should only protect urls with
protocol set to ``saml2``. Therefore, <Location> directive in the Apache
config should enfore this, instead of accepting every protocol.
Mind that a vhost should still accept all the protocols.
