Are CAS redirects incompatible with Google web crawler?

[Kristin Coles]

Hi guys,
I have a working Single Sign On solution (which wouldn't have been possible
without this forum). However this made our webpages incompatible with
Google's web crawler (Googlebot)? When I use "Google Webmaster tools" too
see our website logs, I now see thousands of Redirect error messages (which
weren't there before the Single Sign On).

According to the above link, I should "Minimize the number of redirects
needed to follow a link from one page to another" to avoid the Redirect
error messages.

Right now, I am redirecting 3 times for every page visit.
1. Redirect to the CAS server to get a ticket.
2. Redirect back to the page (service url) from the CAS server
3. Self-redirect without the ticket parameter

Is this a common problem with a simple solution? Can anyone please tell me
how to get over this hurdle.

Thank you!
Kristin
