> If an SP fires a WAYF request off to the DS.  The DS does two things wrong:
> 1) It displays IdPs which do not have a SSO binding of "urn:mace:shibboleth:1.0:profiles:AuthnRequest"
> 2) It then throws an NPE if you select it:
> java.lang.NullPointerException

> We need to make the second stop happening.  But we must also fix the first - unlike the "showUnusableIdPs 9which is to do with colocation of SPs and IdPs in the same metadata source, this need not be controlled by configuration.
