Hi Thomas,

Great you figured this out.

Would you mind elaborating a bit about  what you did with respect to
session fixation prevention?

Cheers,
Thomas

Never mind, I found the problem (at least I think I did):

-          SSO session idle: 1 minute
-          Access token lifespan: 1 minute

When the access token has timed out and the application needs to refresh it
the sso session has also timed out already, hence the error.
Setting SSO session idle to 2 minutes or more fixes the issue.

Mit freundlichen Grüßen

Betreff: [keycloak-user] Refesh token error

Hi there,

we're currently integrating two Java server applications via Keycloak and
use a subclass of KeycloakOIDCFilter on the client side.
The subclassing is done mainly to facilitate configuration (which is loaded
from the database) as well as some adjustments on session fixation
prevention and login redirect handling.

It works well so far, with one exception: when the access token times out
and needs to be refreshed, we get the following error:


-          Client: [org.keycloak.adapters.RefreshableKeycloakSecurityContext]
Refresh token failure status: 400
{"error":"invalid_grant","error_description":"Refresh
token expired"}

-          Keycloak: [org.keycloak.events] type=REFRESH_TOKEN_ERROR,
realmId=our_realm, clientId=our_client, userId=null, ipAddress=127.0.0.1,
error=invalid_token, grant_type=refresh_token, client_auth_method=client-
secret

So far I could verify that the refresh token is not null so it seems to
either be invalid or the request is faulty.

For testing purposes we have set the following timeouts:


-          SSO session idle: 1 minute

-          SSO session max: 10 hours

-          Access token lifespan: 1 minute

-          Access token lifespan for implicit flow: 1 minute

The client has the following settings:


-          Only standard flow enabled

-          Access type: confidential

-          Client protocol: openid-connect

Any idea what could cause that error or where we should look at?

Thanks in advance,

Thomas
