I want to use keycloak in my Spring boot application, but I need user data in my business logic. I want to keep keycloak and business logic in different databases. I found a tutorial in here https://www.baeldung.com/java-keycloak-custom-user-providers
I use bitnami/keycloak in docker environment but in this image doesn't contains custom-user-provider option. It contains ldap and kerberos only. How can I add this option to bitnami/keycloak or is there a docker image of keycloak which contains this option?
thx

I tried the project from here. It works for me.
And my custom-user-provider here.

I have setup Keycloak as a SAML broker, and authentication is done by an external IdP provided by the authorities. Users logging in using this IdP are all accepted and all we need from Keycloak is an OAuth token to access our system.
I have tried both the default setup using H2 and running with an external MariaDB.
The external IdP provides us with a full name of the user and a personal ID. Both data are covered by GDPR and I really do not like the sound of storing that data in a database running in the DMZ. Opening up for Keycloak to access a database in the backend is also not a good solution, especially when I do not need users to be stored.
The benefit of running without a database is that I have a simpler DMZ setup as I really do not need to store anything about the users but on the backend.
Do I need a database, and if not how do I run Keycloak without it?

Yes, however, out-of-the-box Keycloak runs without having to deploy any external DB. From the Keycloak official documentation section Relational Database Setup one can read:
Keycloak comes with its own embedded Java-based relational database
called H2. This is the default database that Keycloak will use to
persist data and really only exists so that you can run the
authentication server out of the box.
So out-of-the-box you cannot run Keycloak without a DB.
That being said from the same documentation on can read:
We highly recommend that you replace it with a more production ready external database. The H2 database is not very viable in high concurrency situations and should not be used in a cluster either.
So regarding this:
The benefit running without a database is that I have a simpler DMZ
setup as I really do not need to store anything about the users but
on the backend.
You would still be better offer deploying another DB, because Keycloak stores more than just the users information in DB (e.g., realm information, groups, roles and so on).
The external IdP provides us with a full name of the user and a
personal ID. Both data are covered by GDPR and I really do not like
the sound of storing that data in a database running in the DMZ.
Opening up for Keycloak to access a database in the backend is also
not a good solution, especially when I do not need users to be stored.
You can configured that IDP and Keycloak in a manner that the users are not imported to the Keycloak whenever those user authenticate.
I have managed to set up a Keycloak server embedded in a Spring Boot Application successfully, following this tutorial:
Keycloak Embedded in a Spring Boot Application
in order to avoid setting it up manually.
Since I am dealing with an old implementation that already has it's own DB, I decided to use Keycloak's User Storage SPI to connect to an external postgresql DB and use this for authentication instead of Keycloak DB.
To do this, I followed the tutorial on Keycloak documentation, but it envolves a standalone Keycloak server, creating a .jar with the custom provider and injecting it to <pathToKeycloak>/standalone/deployments/.
I have created an implementation that works with a standalone Keycloak server, but now I want to include it to the embedded one. Is it possible to use a Keycloak server Embedded in a Spring Boot Application and also have an embedded custom User Storage Provider, to avoid setting up manually?
If you have already implemented the provider and the provider factory, you only need to declare the provider factory class in the resources/META-INF/services/org.keycloak.storage.UserStorageProviderFactory file.
Then you can log in to the administration console and enable user storage provider on the User Federation page.
What can it be for, what logic can be there?
I suppose there should be a connection to keycloak, maybe checking access to create roles and users, am I right or wrong?
It may mean that you need to deploy Keycloak in its own container, separate from the apps.
I'm trying to setup Rancher to use Keycloak as an authentication provider and following the setups laid out here. The last step says to export the metadata in the SAML Metadata IDPSSODescriptor format but I only see SAML Metadata SPSSODescriptor as an option. I've tried using that but authentication isn't working - it opens another window with the same Keycloak setup page when clicking the Authenticate with Keycloak button to validate the setup. There are no errors in the Docker logs for either the Rancher or Keycloak containers when running docker logs CONTAINER command.
I'm wondering if I need to do something specific to setup Keycloak as an IDP to get the correct metadata option but I can't find anything in their documentation.
For Keycloak 6.0 and up, along with the location of the IDPSSODescriptor even its format has changed. This doc explains how that can be edited to be used by Rancher
From the Installation tab, choose the SAML Metadata IDPSSODescriptor format option and download your file.
Or you can directly visit Keycloak URL with IDPSSODescriptor metadata:
https://<keycloak-domain>/auth/realms/<realm>/protocol/saml/descriptor
I am using Bluemix SSO service for user authentication and configured the Cloud Directory identity source as my identity provider. The SSO implementation is working perfectly fine for the Bluemix applications.
However, I have a need to add few custom user attributes and retrieve them as part of the user profile details once the authentication is successful. The Cloud Directory identity source only supports name & email as the user attributes and doesn't provide any feature to add additional custom attributes.
Is it possible to add any custom user attributes to Cloud Directory identity source? If not, what is the best way to configure the custom user attributes when using Bluemix SSO service?
It is not possible to add additional custom attributes using the Cloud Directory of Bluemix SSO (example: roles). There is not a best way to configure the custom user attributes, but you could develop your own login system. For example if you are using Bluemix nodejs runtime you could use the passport module and store all user information in a specific table of your DB. In this way you can manage the login and other custom fields. An alternative is to use SSO Cloud Directory, retrieve the username information from the SSO service in the session and use it as a key to retrieve other DB fields (roles, numbers, address).
