The above documentation doesn't have a "Default" column so maybe it
doesn't specify the default values the IDP would use if none are
configured?
But even then a default would only apply if the property wasn't set,
but you did set it, only to empty value?

I may still be misunderstanding this but AFAICT it works as desiged:
You told the IDP to get everything by setting the property to nothing,
That's LDAP search request attribtues for you.
