Keycloak-js adapter ES6/Promise
by Alexander Philippi
Hi,
I start using the javascript adapter this week. The documentation https://www.keycloak.org/docs/4.6/securing_apps/#_javascript_adapter "says" that the init(...) function should returns a Promise.
After installing the official(?) javascript adapter with "npm install keycloak-js" I only get the old "success" function as return value.
I don't understand what I am doing wrong here. Shouldn't I get a keycloak.js file with a Promise in it? Also I wonder if the keycloak-js adapter should be on ES6 so I am able to do an "import Keycloak from "keycloak-js"". I don't find any information about on https://github.com/keycloak/keycloak-js-bower. Since 4.0.0-beta nothing changed here.
Best Regards
Alex

Updating user attributes within an Authenticator
by marco.scheuermann＠daimler.com
Hi community,
is there a way to update custom user attributes within an Authenticator?
I currently cannot find any API which allows to update an existing user.
I only can find this for credentials:
UserCredentialModel userCredentialModel = new UserCredentialModel();
userCredentialModel.setType(UserCredentialModel.PASSWORD);
userCredentialModel.setValue(“password”);
session.userCredentialManager().updateCredential(realmModel, userModel, userCredentialModel);
How can I update custom user attributes?
Thank you,
Marco

How to add Authorization (policies) for public clients in keycloak
by Shubham Akodiya
Hi,
I've one public client 'react' which uses the implicit grant for
authentication. Now I want to secure this app back-end APIs, thus need to
apply the authorization (policy, resource) settings. Is there any way to
use the *Authorization* settings for the public client?
As per my understanding, Authorization (policy, resource, scope) settings
does not apply for *Public (Client Protocol)* client, It only for *Credential
(Client Protocol) *client. Now the problem here is that when a user tries
to log in using *credential-keycloak-client, *In that case, we need to use
the *client_secret key* in front-end which would make the application more
vulnerable.
Let me know If my understanding is incorrect and feel free to share another
approach to resolve this issue.
Thanks,
Shubham Akodiya

Theoretical max number of clients Kecyloak can handle
by Daniel Fernandez Rodriguez
Hi All,
What's the theoretical max number of clients Keycloak can handle
efficiently?
I'm doing some tests where I created around 10000 clients (saml &
openid, all under the same realm) and now every operation that has to do
with clients (list them, create new one, get one by ID, etc) became
extremely slow and sometimes they even timeout. The other API endpoints
seem to perform just fine.
I'm using 4.6.0.Final and MySQL DB as a data store.
Are there some options I can tweak to improve the performance with a few
thousands clients (ideally around 50K)? Will postgres perform better?
Thanks a lot,
Daniel.

SPI with a third party database. Could not find any META-INF/persistence.xml file in the classpath
by Luis Rodríguez Fernández
Hello there,
I am using the standalone server distribution [1].
We need to extend the keycloak server [2] and we need to access a third
party database to get some data.
I developed a sample domain extension based on the keycloak example domain
extension [3]. The deployment of this example one works at the first try,
thanks!!!
My sample domain extension access a third party database (mysql), so in
wildfly...
- I install the mysql driver
- I create a datasource
... and in my sample I create a META-INF/persistence.xml
<persistence version>
<persistence-unit name="JavaHelps" transaction-type="RESOURCE_LOCAL">
<non-jta-data-source>java:/MySqlDS</non-jta-data-source>
<class>my.entity.Class</class>
<properties>
<property name="hibernate.dialect"
value="org.hibernate.dialect.MySQLDialect"/>
</properties>
</persistence-unit>
</persistence>
I add my sample $KEYCLOAK_HOME/bin/jboss-cli.sh --command="module add
--name=...
And it seems that wildfly likes evrything (from standard output), you can
see below part of the wildfly output at startup time. However when I run it
I get:
Uncaught server error: java.lang.ExceptionInInitializerError.... Caused by:
javax.persistence.PersistenceException: No Persistence provider for
EntityManager named JavaHelps
I found a workaround: having a deeper look at the standard output I saw
this message...
parse checking if
"$KEYCLOAK_HOMEl/modules/system/layers/keycloak/org/keycloak/keycloak-server-subsystem/main/server-war/WEB-INF/classes/META-INF/persistence.xml"
exists, result = false
10:59:55,279 TRACE [org.jboss.as.jpa] (MSC service thread 1-1) parsed
persistence unit definitions for war server-war
... so if I copy my persistence.xml to that location my domain extension
sample WORKS! My question is WHY???
Any thoughts on this?
Thanks in advance,
Luis

keucloak Hash Algorithm
by Dimitris Charlaftis
Hello,
I use keykloak 4.5 and i have set up a user federation to an ldap directory
that uses SHA-1 password encoding.
In order to login to a realm that is connected to that ldap, I use the ldap
username and the SHA-1 encoded password in the login form for the time
being.
This is not good for common users!
All i want is this:
The user puts his username / password in plain text and keycloak transforms
that password in plain text in the login form to the SHA-1 equivalent (that's how our ldap directory works..) , so
that the ldap authorization succeeds.
In your password policy docs you state "See the Server Developer
Guide<https://keycloak.gitbooks.io/server-developer-guide/content/> on how
to plug in your own algorithm". Server dev guide does not have that
information, where is it?
Thanks in advance,
Dimitris

Keycloak javascript client iframe policy
by Lukasz Lech
Hello,
I haven't looked in internals how Javascript Keycloak client is speaking with keycloak server until the token refresh has stopped to work in one of our instalations, which was because firewall was adding per default HTTP header X-Frame-Options: sameorigin. Then I've found out Keycloak client is creating and manipulating iframe.
Is this solution really safe against CSRF attacks? I'm not an expert in that domain, but I've read recommendations to use Authorization: Bearer headers and call API directly, so I don't understand, why is this Iframe needed.
I have a bit problem now explaining WHY do we need to use Iframes and how (un)safe is it...
Best regards,

Library for external HTTP calls.
by marco.scheuermann＠daimler.com
Hi community,
I wrote a keycloak extension based on Authenticator SPI.
What is currently the preferred way to do HTTP calls to an external system within a provider module?
Which library should I use for that purpose?
Should I use an external one, like e.g. Apache HTTP Client or a lib already packaged with keycloak.
Thank you,
Marco
