The Search Appliance itself needs read access to the entire set of URLs
in order to build a search index. Therefore, before walking a
protected data set for Results Authorization, it may be necessary to
fill out the Login Info setting (here)
under All Walk Settings with a full-access admin type account,
so that the Search Appliance can walk the data.
Or it may be necessary to fill out a Primer URL
(here) containing login info to submit to a
site's login form, so that the Search Appliance can obtain the login cookies
needed for access to the rest of the site.
