I am getting convinced this is not UI bug. There is something wrong with keystone roles configuration. Infrastructure dashboard has permissions set to "permissions = ('openstack.roles.admin',)". When I remove this, I get over that error and I am able to display for example service configuration page but I am getting Forbidden 403 a on overview page (dashboard/infrastructure) on ironic node list call, which probably requires the role permission too.

James, are you saying you can't reproduce above *unless* ssl is turned on on the undercloud?

so i reconfigured Horizon to use the internalURL's instead of the publicURL's. that got me past the SSL error.

However, I'm still getting the same error in the UI.

From what I can tell, it has to do with the admin user having the swiftoperator role. We added the swiftoperator role to the admin user so that the admin user can query the swift bugs for the data saved by ironic-discoverd.

What I see happening is that keystone is only returning the first role associated with the user. I've reproduced this in environments with undercloud SSL and non-SSL in place. If the database id of the service project (associated with the swiftoperator role) comes before (a-z sorted) the admin project, then keystone returns that the admin user is only associated with the swiftoperator role. Likewise, if the admin project is sorted first (such as the db id of the admin project starting with 'a', and the db id of the service project starting with 'b'), then I can login to the UI fine.

If I put a breakpoint in the code and inspect the data returned from Keystone for the admin user at line 81, /usr/lib/python2.7/site-packages/keystoneclient/auth/identity/v2.py, if I pp resp_data, I see:

(Pdb) pp resp_data

So you can see in roles that only swiftoperator is returned.

ok, i see why it's taking only the first project now.

if you dont specify a project, it takes the first one. you can see in /usr/lib/python2.7/site-packages/openstack_auth/backend.py around line 55, the loop "for project in projects..." will break as soon as you get a scoped auth token for the first project. So, if the service project is sorted first before admin, you get the service project, where the admin user is only associated with the swiftoperator role.

that's actually around line 155

i confirmed that if you give the admin user the admin role in the service project via:

openstack role add --user admin --project service admin

you can login fine

I've ran : 
openstack role add --user admin --project service admin

on Virt HA+isoltaed network env and then was able to access the Undercloud UI

(also have reproduced the issue before it...)

just waiting for a CI pass on the gate for this patch. the first run failed due to the regression caused by https://bugzilla.redhat.com/show_bug.cgi?id=1236136

the revert for that has landed and built into a new poodle. I've rekicked the CI job for this one:
https://rhos-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/RDO/view/rdo-manager/job/rdo_manager-gate_instack_undercloud-downstream-rhos-7_director/28/

CI passed, merged the commit, did build: instack-undercloud-2.1.2-22.el7ost
