We currently have CAS configured as a SSO gateway for a test implementation of 
Google Apps. Everything is working great, except that we do not want our 
primary net ID to be the default email address used within GMail. After 
speaking with Google, they
recommend passing the preferred email address within the SAML request.  Is it 
possible to configure the CAS ArgumentExtractor to take a field from AD/LDAP 
and pass it along in the SAML request for Google to use?  If so, how would we 
go about doing that?

Here is the Google response to our initial inquiry:
As for your question about usernames being different from email addresses. This 
is something that you can do with our Single Sign On API. It will be included 
in the code that you develop, but basically, you will authenticate off of your 
system, we will
never see that user name and when you send the token back to us it will include 
the email address that you have assigned. I have included documentation on the 
API below. Let me know if you have additional questions after looking at it, 
and I can have you
consult a technical specialist.�
