Multiple entitiIDs on Single SP

[Joshua Brodie]

Hi:

I have three applications, with distinct entityIDs, on a single SP.

1) Is it possible to ensure people to log-in to each of the
applications separately?
    i.e. if user  logs-in to application A, and when they want to
access application B, they are forced to log-in again.


2) Is it possible to have different log-outs for each of the applications
i.e. user is logged in to all three applications, decides to only want
to log-out from application A.
