SP 3.1.0 unable to handle empty discoveryURL attribute

[Wessel, Keith]

All,

Not sure if this was intended behavior, but our stock shibboleth2.xml for campus used to have discoveryProtocol set to SAMLDS and discoveryURL set to "". The upgrade to 3.1.0 seems to choak on this.

We did this for ease of our SP operators to switch from using a single IdP configuration to using a DS. Of course,we can change this, but I saw nothing in the release notes related to this parsing change, and I wondered if it was intended or a bug.

Thanks,
Keith
