Interesting issue regarding group required extension

[toddas]

Hi after I set up my required group it lets me log in without the group anyway. I am getting this warning WARN [org.keycloak.events] (default task-1163) type=LOGIN_ERROR, realmId=realmname, clientId=clientid, userId=null, ipAddress=localipadress, error=rejected_by_user, auth_method=saml, redirect_uri=realm/sso/auth/samlp, code_id=560cd383-5c91-497b-89e1-213516516, username=myusername, authSessionParentId=213213132-5c91-497b-89e1-4dfd11a0c332, authSessionTabId=1321321321

Please help I am using this flow:

Thank you in advance I am using 10.0.1 in standalone mode

@toddas
Maybe your problem refers to this error in flow? Did you to try put 'Require Group' on different level?

@toddas I use a different flow.

Although I can see the expected behaviour when users not in "test" group can not login, I do not like that I do not see in the debug logs the message I expect reading the source code. The message I expect in logs is:

But this is what I get: ( similar to yours )

And this is what I get when the user IS in the group:

I am still debugging, but if anyone can lead me to the right place to understand this behaviour I would be glad.

I highly recommend you to 'override' behavior when user is not in group. It allows you to see auth error in your browser.

if (!isMemberOfGroup(realm, user, groupPath)) {

            String errorMessage = "Access denied because of missing group membership. realm=%s username=%s groupPath=%s";
            LOG.debugf(errorMessage, realm.getName(), user.getUsername(), groupPath);
            Response errorResponse = context.form()
                    .setError(errorMessage, null)
                    .createForm("error.ftl");
            context.failure(AuthenticationFlowError.INVALID_USER, errorResponse);
            return;
        }
