Grouper Users - Open Discussion List

["GW Brown, Information Systems and Computing" <>]

The UI is pretty standard and does depend on Jsessionid cookies. I doubt it 
would work straight off in a non sticky application server cluster - I 
haven't checked to see that all session data is serializable, however, we 
would be willing to look at making session data serializable.

Terracotta looks interesting, but I've no idea if it would work well with 
Grouper. Currently this would be out of scope for the core Grouper project, 
however, if you were undertaking such a project we would be interested to 
know the results and would try to support you where practical.
