[kepler-dev] adding user login interface to Vergil

[Laura L. Downey]

Okay well I guess I'm confused over this whole issue then.  Because I
thought I understood from discussions with Ilkay that we wanted to let the
users know on some high level what they have access to.  And yes I know just
because you have permission to access a specific server doesn't mean you
have access to every single file on that server.  I log on to lternet.edu
and I don't have access to all files but I know I'm logged in at least and
have access to some of the resources there.  If I not logged in then I know
I can't get to anything there.

And reading some of the other comments today it appears that we are saying
people will have to "log in" and be authenticated to various domains.  What
am I missing here?  I thought we were going to a single sign on so that
users didn't have to sign on to tons of different systems....

My head hurts... ;-)

Well, having authenticated to a domain (aka ~server) implies nothing
about whether a user may or may not have access to the objects on that
or related  servers.  So saying a user has been "authenticated" to a
server (which we can list) tells us nothing about what they have access
to on that server.  So we can not generate even a high-level list of
resources they can access.
