[kolla-ansible][openid connect] You are not authorized to perform the requested action

10 May 2025

      Hello, 

I don't know if this is the right place to ask for help - if not, please direct me to the right place.

I have setup kolla-ansible on a single node following the quick start guide [0]. It works fine for a first deployment. I used the stable/2024.2 branch of the kolla-ansible and set the openstack version to 2024.2 in my configuration:

globals.yml:
---
openstack_region_name: "Kolla-1"

openstack_release: 2024.2
kolla_base_distro: "ubuntu"

kolla_internal_vip_address: "192.168.122.17"
network_interface: "enp1s0"
neutron_external_interface: "enp7s0"

openstack_logging_debug: "True"
---

Now I want to configure identity federation with keycloak as the idp, following the kolla-ansible guide [1]. Logging in with keycloak works, but when returning back to openstack, I get stuck at this url with an error 403:

http://192.168.122.17:5000/v3/auth/OS-FEDERATION/identity_providers/keycloak...
{
  "error": {
    "code": 403,
    "message": "You are not authorized to perform the requested action.",
    "title": "Forbidden"
  }
}

This is my kolla-ansible configuration for oidc:

globals.yml:
---
keystone_identity_providers:
  - name: "keycloak"
    openstack_domain: "federated_domain"
    protocol: "openid"
    identifier: "https://key.example.de/realms/master/"
    public_name: "keycloak"
    attribute_mapping: "attribute_mapping_keycloak"
    metadata_folder: "/etc/kolla/openid/meta-idp"
keystone_identity_mappings:
  - name: "attribute_mapping_keycloak"
    file: "/etc/kolla/openid/attribute_mapping.json"
---

attribute_mapping.json:
---
[
    {
        "local": [
            {
                "user": {
                    "name": "{0}",
                    "email": "{1}"
                },
                "group": {
                    "domain": {
                        "name": "federated_domain"
                    },
                    "name": "federated_users"
                }
            }
        ],
        "remote": [
            {
                "type": "OIDC-preferred_username"
            },
            {
                "type": "OIDC-email"
            }
        ]
    }
]
---

In the keystone logs, I see this error, but It dosn't make any sense to me. The user is not created in openstack. So I think my mapping is wrong. But from the logs I cannot see if this is the case or if the error is somewhere else. Is it possible to check my mapping or increase the log verbosity so I can track down the error? Or do I have an error in my attribute mapping I need to fix? 

Cheers
Simon
