I need to limit the maximum users that can be created inside a realm.
Unfortunately I couldn’t find any existing solutions. According to ChatGPT there was a realm setting named “Maximum User Count” in v15.0.2 but I couldn’t find any documentation about this.
Is there some existing solution for this or do we need to adjust the keycloak code accordingly?
I’m not aware of there ever being such a limit. I think you could probably write a custom event listener to call the session.users().getUserCount(realm) every time there is REGISTER event or USER.CREATE admin event. There wouldn’t be a good way to limit it (how would you even notify the user?), but at least you could alert yourself when it hit the limit.
I am user Docker and running Keycloak v21. Looking to limit the session count for for client.
There is a step in the Authentication setup that can be used = and a reference to the admin manual.
