I just finished going through this guide to create a Gitorious server on Ubuntu Server 9.10. With a few difficulties, I managed to get through it all, and I can see the default FAQ, contact information, etc. I can also register accounts fine.
When I log in, though, I am redirected to the dashboard. This would be normal behavior, except I'm not logged in when I get there. I can't find any cookies or session variables. Oddly, this only happens when I enter correct login information--when I enter an incorrect login, it stays at the login screen.
I am using a self-signed ssl certificate.
I'll add information at request, but as there are no errors I don't have any solid data on hand.
