[GoogleCodeExporter]

What steps will reproduce the problem?
1.implement GAIL for a domain
2.Go to sites.google.com/a/domain
3.The redirect will not happen properly

What is the expected output? What do you see instead?
Expected result is to see the custom login page. Instead I see a default login 
page of sites with sign in box not appearing

What version of the product are you using? On what operating system?
The brand new version on Win 7. Everything except sites login page is working 
perfectly 

Please provide any additional information below.
I've attached the screen shot of how the sites login page is coming.

I had the same issue. I found that when I went to the my-app-here.appspot.com I 
was redirected to my main https://www.google.com/a/my-site-here. 

Resolution 
The enable SSO setting had not saved correctly in settings. The check box was 
not enabled. I checked it on, saved settings, accepted terms. Then re updated 
the GAIL files.  

C:\appengine>appcfg.py update gail/

And the log in page worked. 

Hope this helps.

Hello PeterVo, 

I am not talking about the general login page. For me also other login page 
comes. Like mail.domain, docs.domain, calendar.domain all points to the custom 
login page. But sites won't, it gives the page as shown in the screenshot. 

I tried the enable SSO setting. Those are all fine.
