keycloak-gatekeeper as a side car container
by Meissa M'baye Sakho
Hello everyone,
I'm looking for an deployment example with keycloak-gatekeeper as side car
in kubernetes or openshift.
If someone has any?

Deploying Keycloak on Openshift with MariaDB persistence produces errors in logs
by Cristi Cioriia
Hello,
While deploying Keycloak 4.5.0.Final in an Openshift environment, using
Mariadb (Galera) as a database produces several exceptions in the logs, all
of them being related to the communication between the Keycloak server and
the database. The access to the Galera server (3 instances) is performed
via a Maxscale proxy. The Galera server, Maxscale (deployment of 3 pods)
and Keycloak (deployment of 2 replicas) are all deployed inside Openshift,
on AWS (1master + 3 workers).
I am hoping you guys can help with fixing these issues.
The errors look like below:
08:40:46,603 WARN

I suspect that the errors come from the way the jdbc data source is
configured. The mariadb configurations related to connections and wait
timeouts are like below:
max_connections=1000
wait_timeout=180
The second issue I noticed was the following: one of the pods in the
deployments (we deploy 2 replicas of Keycloak) sometimes does not start
correctly because of the following exception, which is still related to the
database connection:

The pod is restarted several times it seems, but it does not start
correctly. I deleted the pod and it was recreated automatically by
Openshift and the new pod started correctly.
Then, there is a third issue that I've encountered while trying to login
into the deployed application. While entering some wrong credentials I got
an error page and noticed in the logs that there is still a database
connection error:

After a couple of seconds, the issue dissapeared, probably because Keycloak
was able to get a valid connection from the connection pool.
Thanks in advance for your help.

Automatically login user after account creation via Admin REST client
by Mariusz Chruscielewski - Info.nl
Hi.
Our webapp is using Keycloak Tomcat adapter.
We use Admin REST client to create user account in Keycloak when user subscribes for our PRO account.
We have onboarding flow and for that we would like to login user just after he creates PRO account, so not redirect to keycloak login page and let user fill in credentials, but to do some REST call, or redirects what will cause adapter to login user automatically.
For example: user subscribes for our PRO service, sets username, password, we make account in Keycloak via REST, and then on next step, user is logged in automatically.
Is that possible? I know we can login user using standard Token endpoint, but that is not creating all Keycloak objects in session (KeycloakPrincipal, AccessToken, etc).
Is there any good way to do it?
Regards

user data > 255 characters is causing Exception
by David Erie (US)
Hi,
We are storing some user preference data as attributes in Keycloak, and I am seeing this Exception in the Keycloak log file:

<snip>

Will it be possible to change that DB column definition to have no limit, or a much higher limit? Are there other ways to store long JSON strings with the User besides their attributes?
Thanks,
Dave

Get a GSSCredential when user browser is not in Active Directory domain
by Chris Smith
I have setup my servlet to authenticate a user my web app using Keycloak Active Directory ldap user federation
I can get a Delegated GSSCredential when the SPNEGO enabled browser runs on a workstation in the AD domain.
When the browser workstation is not a member of the AD Domain, Keycloak will authenticate the user id and password entered on the keycloak login page, but there will not be a Delegated GSSCredential in the Access Token in my servlet.
I have a requirement to use the GSSCredential to call programs on an IBM i (AS/400) and JDBC to the IBM i. My IBM i is configured to accept a Kerberos Ticket from Active Directory as an authenticated credential (aka EIM, Enterprise Identity Mapping).
Less than 1% of the users will be using browsers on workstations in the Active Directory domain.
Can Keycloak put a GSSCredential for the logged in user in the Access Token when SPNEGO is not available from the browser?

Securing multitenant microservices
by Pavel Micka
Hi,
We are currently planning how to implement Keycloak to our solution. Our solution is a multitenant application composed of many microservices with fronting API and React.js clients. Our tenants are all using the same instances of the microservices (those are shared).
We will go with implicit token flow, passing the JWT token through all the dependencies to achieve defense-in-depth (aka: the services do the authorization).
So as we'll have many tenants we will also have many realms. Because clients are bound to individual realm, we will need to duplicate (re-register through dynamic registration every client) many times. For the worse, we will probably also use UMA, which is bound to the client, hence the privileges will be duplicated as well...
Now the questions:
1) Is it somehow possible to inherit or template the definition of the realm, so we would only change the "master realm template" and the changes would propagate to all the individual tenant realms
2) If this is not possible, what is the recommended way to support this scenario with many tenants and many services? Especially when we expect that the clients will evolve, hence updating all the clients+uma in many realms may be very painful...
Thanks for your advice!
Pavel
// PS: if there is any good article or presentation how to achieve this, goal, please send it to me. I will be very grateful.

custom REST endpoints with authenticated access
by Svyatoslav Babych
Hi All,
For our application we have implemented custom REST endpoints with authenticated access check like:
this.auth = new AppAuthManager().authenticateBearerToken(session);
if (auth == null) {
throw new NotAuthorizedException("Authorization header must be provided");
}
It works great for all requests except situation when master realm admin tries to call this endpoint at different realm (not his own)
It works at /realms/master/{endpoint}, but doesn't for /realms/{realm}/{endpoint}
Could you please help me wit this ? master admin for access uses: master realm, *admin-cli* client and has *admin* role assigned.
Thank you,
Regards
Svyat

Regarding the email Verification link
by senthil nathan
Dear KeyCloak Users,
We have requirement to get the email verification link URL accessible to public, when we use admin rest
API.
In Our Current architecture application is running with private IP, Key Cloak is hosted in separately,
which can accessible via load balancer. We would like to use the admin rest API for getting the
verification link in email with the load balancer url instead of private IP URL (keycloak and Application
uses private IP for admin rest API communication )
Any help on resolving this issue is appreciated

Connect EAP with third party Identity Manager
by Michael Gulitz
Hello!
We have implemented an JEE application on EAP 7 with three layers (UI
(OpenUI5), REST API, EJB layer) and are using keycloak adapters and
keycloak server in our local environment. This setup works fine so far
with security context in all layers.
But now we have to deploy the application to a different environment and
must connect to a NetIQ identity server via OpenId, but the keycloak
adapter uses its own specific URL pattern, etc.
I cannot find any documentation how to configure EAP to allow
authentication with other identity managers than keycloak or JBoss SSO.
For OAuth Picktlink documentation also points to the keylcoak project.
Can anyone help?
Thanks,
Michael
