keycloak 3.4.0 - Missing relation
by Kevin Hirschmann
Hello everybody,
I am setting up a new keycloak instance (3.4.0) resulting in the following error (Relation does not exist):
INFO [org.keycloak.connections.jpa.updater.liquibase.LiquibaseJpaUpdaterProvider] (ServerService Thread Pool -- 78) Updating database. Using changelog META-INF/jpa-changelog-master.xml
ERROR [org.keycloak.connections.jpa.updater.liquibase.conn.DefaultLiquibaseConnectionProvider] (ServerService Thread Pool -- 78) Change Set META-INF/jpa-changelog-authz-3.4.0.CR1.xml::authz-3.4.0.CR1-resource-server-pk-change-part2::glavoie@gmail.com failed. Error: FEHLER: Relation Ųesource_server_policyӠexistiert nicht
Position: 8 [Failed SQL: UPDATE RESOURCE_SERVER_POLICY p SET RESOURCE_SERVER_CLIENT_ID = (SELECT CLIENT_ID FROM RESOURCE_SERVER s WHERE s.ID = p.RESOURCE_SERVER_ID)]: liquibase.exception.DatabaseException: FEHLER: Relation Ųesource_server_policyӠexistiert nicht
Position: 8 [Failed SQL: UPDATE RESOURCE_SERVER_POLICY p SET RESOURCE_SERVER_CLIENT_ID = (SELECT CLIENT_ID FROM RESOURCE_SERVER s WHERE s.ID = p.RESOURCE_SERVER_ID)]
The problem only occurs, if I do NOT use the default schema. If I use the default schema everything is great.
How can I work around this problem?
Thx for your help

Re: [keycloak-user] Authorization transfer
by Corentin Dupont
I see, so I need to create "mydomain" as a resource.
But what should be the type for both "mydomain" and "myhouse"? Should it be
something like "domain:mydomain"?
What I would like is to grant different access to users to that domain.
For example: user Bob can only view resources in domain "mydomain".
User Alice can view and delete resources in "mydomain".
Should I create a "User Policy" with the list of users that have access?
If I understand, I need to use the "resource-based" permission. However it
does not seem to let me select the scopes (as in my example: Bob can only
view, but Alice can delete).
Another question: how to invoke the API for typed resources?
I have:
curl -X POST -H "Content-Type: application/json" -H "Authorization: Bearer
$TOKEN" -d '{
"permissions" : [
{
"resource_set_name" : "Sensors",
"scopes" : [
"view"
]
}
]
}' "http://localhost:8080/auth/realms/waziup/authz/entitlement/waziup"
But this uses the name of the resource, so I am not sure. Is there a
reference for this API?
Thanks a lot
PS. I found some minor bugs related to the API, should I report them here
or create a JIRA?

Unable to use Implicit Flow in Spring Security
by HALLEGUEN, Roderic
Hi,
I followed the two articles on the blog (https://developers.redhat.com/video/youtube/O5ePCWON08Y/) to make Keycoak work with Spring Security. It works nice, but I'm only able to use the standard flow. Is there something to configure in Spring Security to make it work with the Implicit flow ? I didn't find anything about this in the documentations.
Thank's for your help !

UMA Authorization
by Damian Czaja
Hello guys,
AFAIK Keycloak currently does not have full UMA support and for e.x. it's
not possible for users to manage resources they own. There already a PR for
KEYCLOAK-3169 on that.
First question:
How is the "owner" of the resource set when using the Resource Registration
Endpoint (
https://docs.kantarainitiative.org/uma/rec-oauth-resource-reg-v1_0_1.html)?
Is it set to the "subject" of the PAT token used to register the resource
or is it always the Resource Server, who registered it?
Second question:
>From what I know in UMA to get the Permission Ticket you need to use the
PAT of the Resource Owner. In case the Resource Owner is an End-User does
it mean the Resource Server will need to perform OAuth2 with the End-user
and store the PAT somewhere to be able to issue Permission Tickets to
Requesting Parties anytime, without the active present of the End-user?
Best regards,
Damian

org.hibernate.LazyInitializationException (could not initialize proxy - no Session) when getting user attributes
by Ilya Korol
Hi. I've wrote some implementation of org.keycloak.timer.ScheduledTask
that should periodically conditionally delete some users, depending on
their attribute values:
@Override
public void run(KeycloakSession session) {
long currentTime =
TimeUnit.MILLISECONDS.toSeconds(Time.currentTimeMillis());
RealmModel realm; // appropriate realm was set
GroupModel group; // appropriate group was set
session.userLocalStorage()
.getGroupMembers(realm, group).stream()
.filter(user -> isNotVerified(user) &&
isExpired(user, currentTime))
.forEach(user -> {
session.userLocalStorage().removeUser(realm, user);
});
}
private boolean isNotVerified(UserModel user) {
return user.getFirstAttribute(UserAttributes.STATUS) != null
&&
user.getFirstAttribute(UserAttributes.STATUS).equals(UserStatuses.NOT_VERIFIED);
}
private boolean isExpired(UserModel user, long currentTime) {
return
TimeUnit.MILLISECONDS.toSeconds(user.getCreatedTimestamp()) +
expirationTimeout < currentTime;
}
When it runs i got following exception in method isNotVerified(UserModel
user) for users that don't have any attributes. (For users with any
attributes this will work)

I found a workaround by surrounding attributes verification with
try/catch RuntimeException. In debugger i checked that
session.getTransactionManager.isActive() returns true. So i'm
interesting in possible problems here. Do i have any mistakes in my code
or there is a some kind of bug? Should it be moved to Jira?

User registration outside of Keycloak login form
by Ilya Korol
You should use your custom Authenticator (see docs for Server
development -> Authentication SPI). So the idea is to put this
authenticator (Optional requirement) inside browser flow right after
Cookie. It will check whether user is authenticated or not (if user was
authenticated it means that Cookie worked). Then it will show form that
you described via its challenge() method, and process user reaction in
action() method. If you don't fully understand what i've wrote check
docs and you definitely should get the idea. Cheers.

Integrating Login With Facebook
by Madhan Kumar S P
Hello,
I am trying to integrate the Keycloak with Facebook social plugin.
I had gone through the examples and documentation. This works fine if I use
the Keycloak hosted Login Page.
What I need is that we want to host our own login page and use the
Keycloak APIs to register the user and login.
I mean, I want to host our Sign Up/Login Page. When the user clicks
on the Login with Facebook, we want to redirect the user to FB and get the
approval and collect the details, create the user details that we need for
our application. Then register the user on the Keycloak.
I don’t see any documentation for this. I would be really grateful
if you can shed some light on this and point to the documentation that
would help me in achieving this.
Thanks & Regards,
Madhan Kumar S P
