We would change from (being logged in would be required):
curl -3 -u "{PushApplicationID}:{MasterSecret}"
-v -H "Accept: application/json" -H "Content-type:
application/json"
-X POST
To:
curl -3
-v -H "PushApplicationID: XXXXXX" -H "MasterSecret: 42" \
-H "Accept: application/json" -H "Content-type:
application/json"
-X POST
That sounds like the most safe change to our client-registration and sender
SDKs. Basically a 'minor' change where we issue the HTTP request.
I'd vote for this change, but only if it is not possible to exclude a few
URLs from Keycloak ;-)
Note, that those excluded endpoints (for device-registration and sender)
don't require any <auth-method> setting in web.xml,
as they implement their own simple HTTP_BASIC handling by querying our
database ;-)

But, yeah - if the exclusion is not possible at all, I like your suggested
header usage fix. IMO that's the one with the fewest risks.

Each application would have the same role "ups-application".

Yes, totally agree on that.

Stian sent to me a message, he might have more ideas about how to
overcome this issue. I will update you guys during this week.
