Jusi,
could you please follow the agreed strategy for Tizen 3.0 implementation.
You are welcome to try to get PAM upstream to accept such a limitation
but I doubt that you will succeed because allowing multiple login
outside of a graphic session can make sense (e.g. ssh connection) and
PAM need to support that operation mode.
When it come to Jira requirements, if I have left them to make believe,
when I wrote them, that multi session was required, please let me know
where you see such indirect statement, so that I clarify the issue.
I just repeat what I said earlier, we have agreed in October 2013, when
architecturing Tizen 3 that multiple sessions would not be used and I
will ask you to comply with that agreement which is not going to be
change any time soon.

It is just wrong place for doing such. If you want it, the only
correct place is PAM, because it is the only entity who sees all
logins. TLM doesn't (and shouldn't) do any authentication on it's own,
all authentication is done by PAM.
It was part of the agreement when Multi user architecture was accepted.
"Multi User concept
• Multiple user, not multiple concurrent user"
Managing multiples session of the same user induce a let of issues for
applications and we agreed that it was not really needed for Tizen and
decided to stay with a single session model.
This to me talks about something different and is in conflict with
multi-seat multi-user JIRA requirements. Of course multi-seat is
pointless without allowing multiple concurrent sessions.
For info, on your Linux desktop, if you open two sessions under X11, you
will see that many applications will be in trouble (try Firefox or
Thunderbird, if you have some time to spare for the fun).
I know those are broken. But IIRC, for example Konqueror works just
fine as well as most other KDE applications.
