Hi,

Two webapps, both protected by CAS.  user is in both apps via SSO.

when user idle timeout kicks in, he is also logged out of CAS, i believe 
this is the correct behavior. Otherwise, after idle timeout, simply 
accessing B will get user in right away, which is a security problem. say, 
User walks away, app's idle timeout kicks in, but SSO session is still 
valid, now, some one else comes and access the app, that person would be 
right in B without being prompted for credentials.

this brings up another usability problem.  say, user is busy in one app A 
and idle in the other app B.  B's idle timeout kicks in and also logged out 
of CAS. User remains in A, but when he access B, he is prompted for 
credentials (no SSO since CAS SSO session was already terminated).

is my understanding correct?

Thanks,
Yan
