[keycloak-user] SSO Session Idle Timeout for Direct

[Schneider, John DODGE CONSULTING SERVICES, LLC]

Hi Stian,

It does make sense when you have two distinct sets of "users", one of which does not include people.  In our case, we have people at a keyboard that we want to timeout after about 15 minutes of inactivity, and we also have external applications running in the background that have no need for a user session per-se and execute many REST service invocations for the same service over several hours.  The applications are active the whole time, but not interacting with the OAuth server.  

If you want to keep things this way, I don't think it's a good idea, but  please at least put in a validation in the admin UI with a warning of "access token timeout should not be less than SSO session idle timeout". 

Thanks,
John

It doesn't really make much sense to have idle timeout shorter than access token timeout. For example in your case above the user session is logged out after 15 min, but an application can still access services using the token for nearly another 4 hours.
