Steps to reproduce:

1. Create a course site with at least 2 sections.
2. Add roster tool.
3. Login as an student of one section.
4. You won't be able to see roster.

If you grant roster.viewgroup permission to student role then you see the list. I think this permission should be granted by default in Sakai OOTB.
It has no sense grant roster.viewallmembers to student or even instructor.

This patch adds roster.viewgroup permission to Student role in !site.template.course. It also be desirable to add something in conversion scripts to modify this template, and check if nothing is affected by this grant.

Other solution could be change the way roster2 is checking permissions, what do you think Adrian?

Comment by Matthew Buckett [ 09-Oct-2014 ]

The permissions Roster2 currently register are:


The code uses roster.viewallmembers to see if the user should be allowed to see the members of the site. org.sakaiproject.roster.impl.SakaiProxyImpl#getRosterSite() but roster also uses the same permissions to assume that you should be able to see the members of all groups.

it seems like there should be a way to allow people to see all the members of the site without having to grant them access to all groups.

Comment by Juan José Meroño Sánchez [ 23-Oct-2014 ]

When a student is enrolled in just one section within a site, Roster1 did not need any permission in the site realm to show the members of his group, it was only checking the group realm looking for the roster.viewgroup permission in order to show the members of the group. This usecase is not working with roster2.

For users with 'roster.viewallmembers' in the site realm, roster1 and roster2 act the same way. The user is able to see all members of the site.

Matthew, do you think that this should be solved by fixing the code rather than adding a new permission to some roles that right now are not able to see anything in roster2 (like students in an OOTB SAKAI)?

Thanks in advance.

Comment by Matthew Jones [ 23-Oct-2014 ]

I feel like the change in RSTR-57 is breaking this. After RSTR-57, it does a precheck in getRosterSite which requires these two permissions in order to work.

Otherwise it goes through and when it calls getViewAbleSiteGroups it actually returns the correct groups based on the old roster permissions. Removing this pre-check makes it work as expected for this issue, even removing the permissions that are added to the group realm(s).

I can't figure out any reason why it's here, but if needed it should be trusting the check in getViewableSiteGroups. as that also does this same security check. (SAK-27501-code.patch)

Thanks Matthew !! I'm going to test your patch and apply if no more comments are added here.

Tested in trunk.

Comment by Juan José Meroño Sánchez [ 27-Nov-2014 ]

After SAK-28028 this is not working on trunk.

Reapplied Juanjo's patch (a.fish@lancaster.ac.uk: rev 315716)

Comment by Neal Caidin [ 01-Dec-2014 ]

Does this need an updated patch? Are we still trying to get this into 10.3 ?

Comment by Juan José Meroño Sánchez [ 01-Dec-2014 ]

This has to be merged again (r315716) only if SAK-28028 (new roster2 UI) is merged into 10.x, but not for 10.3, is it right?
I think we need to link both jiras to keep this in mind.

Comment by Neal Caidin [ 01-Dec-2014 ]

I removed the 10.3Triage label.

Comment by Juan José Meroño Sánchez [ 02-Dec-2014 ]

This was fixed for 10.3, later, it was broken in trunk (due to SAK-28028), and then fixed again for trunk (probably this should have been done in another jira but it was done in this one that was already closed). This will be broken in 10.x only if SAK-28028 is merged into 10.x, so I've closed the jira and changed fix versions to 11 and 10.3. Now is working in trunk and 10.x.

Comment by Neal Caidin [ 02-Dec-2014 ]

Thank you! That was mighty confusing.
