Regular users cannot manage security groups in Horizon

As a regular user (a user without the "admin" role), if I go to Horizon » Project » Compute » Access & Security » Security Groups, by default, the options to

* delete security groups,
* create security groups,
* update security groups,
* create security group rules, and
* delete security group rules

… do not show up.

If my Horizon IP address is 10.12.53.10, the page that should be showing those options would be https://10.12.53.10/project/access_and_security/ under the "Security Groups" tab.

This happens if the "network" (Neutron) service is enabled.

My regular user does have permission to manipulate security groups, which I checked with `nova secgroup-create`, `neutron security-group-delete`, etc.

Also, I could bring up the Horizon interface to create new security groups by going directly to https://10.12.53.10/project/access_and_security/security_groups/create/ , and filling out and submitting the form would create a new security group, but the options to edit or delete it still do not show up in Horizon after creating the new security group.

--------------------------------------------------------------------------

The cause is that "openstack_dashboard/conf/neutron_policy.json" does not contain security group and security group rule policies.

If you go to "openstack_dashboard/dashboards/project/access_and_security/security_groups/tables.py", you can see the allowed() method of each tables.LinkAction. Notice that each checks if the "network" service is enabled, and if so, it sets the policy to check to be (("network", "create_security_group"),), (("network", "delete_security_group"),), and so on.

The problem is that the file that is supposed to contain those policies, "openstack_dashboard/conf/neutron_policy.json", does not contain those policies.

--------------------------------------------------------------------------

To fix the problem, add a comma to the end of the last policy in "openstack_dashboard/conf/neutron_policy.json", then before the closing "}", add the following lines:

    "delete_security_group": "rule:regular_user",
    "create_security_group": "rule:regular_user",
    "update_security_group": "rule:regular_user",
    "get_security_group": "rule:regular_user",
    "create_security_group_rule": "rule:regular_user",
    "delete_security_group_rule": "rule:regular_user"

Now, regular users can manage security groups in Horizon.
