Playing with our test 2013 SharePoint server. Trying to tell the search crawler to index a site on a different farm's web app, but the crawled site is responding with an Access Denied. In the crawling server, I set the site to be crawled as a web site, not a SharePoint site.
I believe the crawled web app can see that a Sharepoint crawler is coming in, and is treating it as the local farm...so it's trying to treat it like the local SharePoint farm search engine...which it's not.
I don't want to add one farm's permissions to the second... I just want things to respond as if any dumb crawler were coming to the door.
the target box is open to all user-agents, and allows anonymous access.
