Eric,

If you're willing to have your forums crawled and indexed by public search 
engines, then you might be saying that you want your forum information to be 
publicly available.  If that's the case, then you may have a mismatch in your 
desired policy (public availability) and your implemented policy (login 
required to access the forums).  You could resolve that such that the forums 
present an unauthenticated guest view and CAS authentication is optional.  Then 
a search engine might be able to crawl the site without logging in.

Example: The Free Software Foundation happens to have an online forum, and use 
CAS for login.

You can go here without logging in:

http://www.fsf.org/associate/forum

So CAS isn't preventing that page from being search engine indexed.  

If you try to access any of the fora on that page, CAS authentication is 
required, so CAS is preventing those pages from being indexed.

If your requirements are such that you want pages to be indexed, you could 
change your policy and your implementation of the CAS integration to allow 
anonymous access to more content.

If you don't want your forum to be available to people who don't log in via 
CAS, then you probably shouldn't want it to be Google indexed, since Google 
indexing will expose information about the forum contents to people who may not 
have logged in via CAS.


This explanation helping any?

Andrew
