Describe the bug:

Users that are not superusers cannot login in Kibana. You can see a trace related to ingest management every time you try to login User not authorized for "/api/ingest_manager/check-permissions": responding with 404

Steps to reproduce:

1. Enable ingest management and fleet in Kibana
2. logout
3. try to login with a user with Kibana_admin role
4. Kibana return a 403 error
5. you see the message User not authorized for "/api/ingest_manager/check-permissions": responding with 404 in logs

Expected behavior:

The user login into Kibana.

Screenshots (if relevant):

Errors in browser console (if relevant):

{"statusCode":403,"error":"Forbidden","message":"Forbidden"}

Provide logs and/or server output (if relevant):

User not authorized for "/api/ingest_manager/check-permissions": responding with 404

Any additional context:

A Kibana without ingest management full configured using the same cluster can login as expected with the same user.

@ruflin I think we do require the super user on everything should we try to require the _kibana_admin_ role?

[nchaulet]

We require user to be superuser and Kibana_admin is not enough to use ingest manager right now, but I think you should see a screen that display that, I am going to investigate

[kuisathaverat]

@ph the thing is that only superusers can login after enable ingest management, all the rest fail to login.

[nchaulet]

Oh got it, I think we are doing some api calls in the ingest manager client side plugin start, that we should not do if the user do not have the right permission.

This PR merged yesterday will fix that https://github.com/elastic/kibana/pull/69505

Just tested with a kibana_admin user
