Chapter 5. Troubleshooting

The file mapping_rules.json has this content:

[
    {
        "local": [
            {
                "user": {
                    "name": "{0}"
                },
                "group": {
                    "domain": {
                        "name": "Default"
                    },
                    "name": "federated_users"
                }
            }
        ],
        "remote": [
            {
                "type": "MELLON_NAME_ID"
            },
            {
                "type": "MELLON_groups",
                "any_one_of": ["openstack-users"]
            }
        ]
    }
]

The file assertion_data.txt has this content:

MELLON_NAME_ID: 'G-90eb44bc-06dc-4a90-aa6e-fb2aa5d5b0de
MELLON_groups: openstack-users;ipausers

If you then run this command:

$ keystone-manage mapping_engine --rules mapping_rules.json --input assertion_data.txt

You should get this mapped result:

{
  "group_ids": [],
  "user": {
    "domain": {
      "id": "Federated"
    },
    "type": "ephemeral",
    "name": "'G-90eb44bc-06dc-4a90-aa6e-fb2aa5d5b0de"
  },
  "group_names": [
    {
      "domain": {
        "name": "Default"
      },
      "name": "federated_users"
    }
  ]
}

Create the following test script in /var/www/cgi-bin/keystone/test with the following content:

import pprint
import webob
import webob.dec


@webob.dec.wsgify
def application(req):
    return webob.Response(pprint.pformat(req.environ),
                          content_type='application/json')

Edit the /var/lib/config-data/puppet-generated/keystone/etc/httpd/conf.d/10-keystone_wsgi_main.conf file setting it to run the test script by temporarily modifying the WSGIScriptAlias directive:

WSGIScriptAlias "/v3/auth/OS-FEDERATION/websso/mapped" "/var/www/cgi-bin/keystone/test"

Restart the container:

podman restart keystone
