[Fim4l] Reasonable lenght of SP's session

In my experience for more complex applications the SP session itself
doesn't play a role because it is only used to setup an application
session, so the SP session might be very short, maybe just 30 seconds.
The application session usually has a relatively short timeout, maybe
between 30 minutes and a few hours. Note that this session timeout is
relevant for Unique_Item and Unique_Title metrics in COUNTER usage reports.
And there might be something like a "remember me" feature which allows
the user to come back later and setup a new application session without
having to authenticate again. I assume your question is about how long
this should be possible? My recommendation would be to not offer a
"remember me" feature in comination with FIM because (a) the IdP usually
supports single sign-on so authenticating again should be easy (at least
when it is easy to select the institution) and (b) this might cause
problems when there is an incident like a mass download - after some
time the library might no longer be able to identify the user (in our
case: after a week).
So if Elsevier would offer a "remember me" feature and only authenticate
users after longer periods like a month or six months, Elsevier would
have to take responsibility for usage by users no longer affiliated with
the institution and for incidents that might happen during this period.
And of course this should align with the license agreements.

Should we confirm with the library that a user is still affiliated with it whenever a user wants to access the service (such as ScienceDirect)? Or every day? Every week? Every month? Every 6 months?
