Bug tracking that works with Google Apps?

Are there any hosted bug tracking systems that work natively with Google Apps for authentication, notification services, etc?

From stackoverflow

• I've played with a good deal of bug tracking systems and have never encountered one that works natively with Google Apps.

• Yes, you can make use of Google Sites, which has the ability to create "issue tracker" pages among other things.

  Anirvan : I'm trying to figure out how to do this, but am totally not finding it. Can you add a description, screenshot, or URL to look at? Thanks!

  lfaraone : See http://yfrog.com/eescreenshot1gzgp and http://yfrog.com/e0screenshotwp. On the create-a-new-page screen select "list", and it takes you to the latter page.

  lfaraone : Did that work for you?

  crosenblum : Neat....i hope i can convince my fellow workers to be interested in this lol...i doubt it.
