Hi, since 11.3.6 the management ui supports two modes to login with OAuth 2.0 protocol. This mode is configured via a new setting called `management.oauth_initiated_logon_type` (It is explained in
https://www.rabbitmq.com/management.html#oauth2-authentication under "Identity-Provider initiated logon" section).
The default mode is `sp_initiated` which means users comes to RabbitMQ without any token. RabbitMQ instead, takes the user to the configured Idp to authenticate and get a token.
In the `idp_initiated` mode, users come straight to RabbitMQ's ´/login` endpoint with a token which was signed with the configured signing key in RabbitMQ. if the token is valid and the user has the right permissions, the user is redirected to the overview page.
The use case you propose is not supported today. In other words, RabbitMQ will not look into the `Authorization` header for a token.
Could you share more details of your setup?
