Cannot sign in to Chrome using Crowd (redirect loop)

I have a Crowd server set up for development and test purposes. Crowd is connected with Google Apps domain (kicnet.org) for Single Sign On.
Everything works fine for GMail, Google Sites and custom Google Apps webapp.
However, when I'm trying to sign in to Google Chrome browser (as is outlined here: http://support.google.com/chrome/bin/answer.py?hl=en&answer=165139), I'm entering redirect loop when submitting user credentials.
Loop is like this:

This prevents us from using very useful Google functionality.

Btw, Google Dashboard (https://www.google.com/settings/chrome/sync) works correctly. Only Google Chrome sign loops.
