I think we agreed that the Gateways would be responsible for user management, but maybe that
is at a different level?

Thanks Raman,
I looked into the tables. It looks to be a viable option.
But is it okay to manage the users from the Airavata server itself?

Looking at Airavata Data model, there is project which is equivalent to User group. A project
can have multiple user for a gateway and a gateway can have multiple projects.

As an end user, I think even with just a single tool, the argument for a group is there.
As Saminda suggested, one may wish to have a join area to work in with a group, and individual
work you aren't ready to share, even with just a single tool.

Because a Gateway is wide open, it is easy to imagine a case where there are several groups,
each with (potentially overlapping) users, who all are working with Amber for different projects..
Agreed. I totally forgot about shared projects scenario. Thanks for pointing it out Mark.

I'm not an expert on the Amber usecase, but I suppose it is possible to have multiple user
groups for a single usecase. It could be to have a shared space of data hidden from each user
group. It could be to author access/privilledges to the portal or resources depending on the
user group.
I would assume the mapping of user to usergroups would be many to one mapping. Unlike user
roles I don't think it is sensible to have users being mapped to multiple groups (there is
a whole area of security to consider here).

(I do have to note that usergroup IMO is not a must concept for a science gateway)

Hi all,

Can someone explain to me the mapping of users to groups in a Science Gateway? ( This is regarding
the Amber usecase).

Can there be multiple user groups in a gateway portal when it comes to just one usecase?
ex: If we have only one usecase for the portal ( such as Amber)
