Correct, the first step is a redirect from KeyCloak to the ADFS server to authenticate the
user.
This initial redirect happens only once.
After that we see more than 1000 requests hitting our KeyCloak URL with a redirect from
that ADFS server and redirecting back to the ADFS server.
I mean like this:
KeyCloak -> ADFS
ADFS -> KeyCloak
KeyCloak -> ADFS
ADFS -> KeyCloak
KeyCloak -> ADFS
ADFS -> KeyCloak
We reached out to our customer to check if one of their users has a different cookie
configuration in his/her browser.
Best way forward seems to be to locate the storm generator first.

How can ADFS make requests to Keycloak? Wouldn't it be other way around?

You are absolutely right, but at the time this was all the
information I had and just wanted to check if anyone else had a similar experience.
We narrowed it down to 1 realm receiving a lot of requests. All the requests are
originating from the customer's ADFS that fills up our log. It seems that those
requests aren't even logged at the keycloak realm, but the "logout all
sessions" button in the sessions part of the realm does stop the storm.
To answer your questions, customers didn't see the login page and keycloak didn't
process HTTP requests anymore. KeyCloak is just one instance. I don't know the amount
of database connections at that time. Will certainly look into those metrics next time.

You'll need to narrow down the problem more. i.e. What does "can't login
anymore" mean? Do customers still see login pages? Can Keycloak still receive and
process HTTP requests? Or is there connection denied? Is Keycloak clustered? Or is it
one instance? How many open database connections does the DB have?
