Cant login to rabbitmq

[mdrio]

Hi, I am trying to configure oauth2 on rabbitmq with keycloak as token issuer. I am following this tutorial. Anyway I am having some trouble, failing to login using both the management API and the pika example.

The management API stdout:

+ CLIENT_ID=mgt_api_client
+ CLIENT_SECRET=LWOuYqJ8gjKg3D2U8CJZDuID3KiRZVDa
+ REALM=test
+ URL=https://localhost:8443/realms/test/protocol/openid-connect/token
++ curl -k https://localhost:8443/realms/test/protocol/openid-connect/token --silent --location --request POST --header 'Content-Type: application/x-www-form-urlencoded' --data-urlencode cli

With this related line in the rabbitmq logs:

2024-11-19 16:26:35.554287+00:00 [warning] <0.903.0> HTTP access denied: user '' - invalid credentials

While the pika example exits with:

python pika-client/producer.py producer kbOFBXI9tANgKUq8vXHLhT6YhbivgXxn
pika version: 1.3.2

With this rabbitmq log:

Reproduction steps

1. add "localhost keycloak rabbitmq" to /etc/hosts
2. make start-keycloak
3. export MODE=keycloak
   make start-rabbitmq
4. make curl-keycloak url=http://localhost:15672/api/overview client_id=mgt_api_client secret=LWOuYqJ8gjKg3D2U8CJZDuID3KiRZVDa
5. python3 --version
   pip install pika
   pip install requests
   python3 pika-client/producer.py producer kbOFBXI9tANgKUq8vXHLhT6YhbivgXxn

Expected behavior

Both management API call and the pika one should login and exit without errors
