Unable to grant role in project to user/group in latest DevStack

[Marcin Zbik]

Git version of Horizon 8.0.0.0rc2 from branch stable/liberty

Steps:
1. Identity -> Projects
2. Select one of projects and edit its members
3. One can add user but no roles to select are shown. No errors in apache log but in firebug console there is: TypeError: role_list is undefined

Some more informations from firebug console:
TypeError: role_list is undefined

And that part of line is indicated:
....current_membership[step_slug][role_id];role_list.push(data_id);horizon.membersh...

I can easily list roles under url: /identity/roles/ and grant roles from CLI level.

It might be connected with LDAP backend for keystone.
I changed from LDAP to SQL backend in keystone and exact same horizon instance was able to list available roles for user (in project).
