Make Jira issues searchable via intranet search engine

unknown

We utilize regain as intranet search engine and now want to be able to find Jira issues there, too.

So somehow we need to index them, but Jira (like the search engine) requires login via username and password.

So my questions:

1. Is it possible to auto-login a HTTP client that accesses Jira from a certain IP?
2. What other alternatives do we have letting the search engine indexing the data without allowing anonymous access to the issues?

I already found out that you can login by URL parameters, but that would require us to append the parameters to every request the search engine does, which is nontrivial.

I wrote a small PHP script that fetches all projects, then fetches the issues in each project and saves the issue's print view locally.

Around that I build index pages for each project (listing all issues) and a list of all project index pages.

This can now be indexed by the regain without problems.

Before doing all that, I created a jira user group "Search", put the searchengine in there and then allowed this group to access all projects.
