It's a nice idea to get FreeIPA on Debian.
Let me point to some Debian resources related to FreeIPA:
http://lists.alioth.debian.org/mailman/listinfo/pkg-freeipa-devel http://qa.debian.org/developer.php?login=pkg-freeipa-devel%40lists.alioth.de...
I don't know who is behind pkg-freeipa-devel@lists.alioth.debian.org. I would recommend sending there an email, CC'ing debian-devel.
I can maintain one or two Debian packages (but not 50) however i'm not an official Debian Developer.
Best regards.
