Hi Brian, Patricia,

Can you change your hard-coded RelayState from:

http://mail.google.com/...

to the actual RelayState which comes with the SAMLRequest?

To see what this value is, go to the service URL (without signing in
first):

http://mail.google.com/a/yourdomain.com

You'll be redirected to your SSO Sigin-in URL with the SAMLRequest and
RelayState parameters.

Take the RelayState parameter, URL-decode it, and replace your current
RelayState in the ACS URL form with this value.

Let me know if you still have this problem.  Thanks.

-alex
