I need to block user access to Keycloak Account client (/auth/realms/[MYREALM]/account) but I need the Rest API provided by this client.
I'm using Keycloak 4.1.0. I have tried to disable account client through keycloak admin panel (/auth/admin/master/console/#/realms/[MYREALM]/clients), but if I disable this client, Account Rest API is no longer working.
There is an Apache in front of this Keycloak and I guess I could filter requests using Apache, but I'm not allowed to do it.
You can remove the client role 'manage_account' for client 'account'.
Go to realm > Configure > Roles > Default Roles > Client Roles > Select 'account' > remove 'manage-account'

we want to access the Keycloak (Version 10) REST API from one of our backend services. To authenticate, we have setup the followings:
new clients within our realm
enabled service account for that client
assigned all [1] roles of “realm-management” to the services account
Accessing the API, e.g. fetching a selected user always results in a 401 response.
Steps to make the requests are:
Retrieve access_token from https://my-keycloak.com/auth/realms/my-realm/protocol/openid-connect/token using grant_type=client_credentials + Client ID + Client Secret
Fetch user from https://my-keycloak.com/auth/realms/my-realm/users/some-user-id-4711
using the Authorization: Bearer $ACCESS_TOKEN with the Token from step 1.
My Question: Is it even possible to use a custom client or do we have to stick to login via admin-cli? How would we need to configure the custom client, to grant access to the REST API.
Thanks,
Martin
[1] Simply setting all roles for the sake of testing, regardless that we only want to read data in the end.
I would like to be able to use auth0 as identity provider, so having all login part done through auth0 and using keycloak as authorization manager, so having all user permission management done through keycloak. Is there any way to do this ?
Yes there is.
Keycloak allows you to create mappers for custom identity providers, so that you can extract roles and attributes from your provider to keycloak. That way you will be able to use ABAC or RBAC in Keycloak, with still user permission management done through Auth0.
First you can add Auth0 as an identity provider through OpenID Connect or SAML2. Go to your Auth0 app config > advanced setttings > endpoints to get all the required information to create a new identity provider.
Then you need to create mappers in your identity provider, so you can import attributes or roles from Auth0 token. Documentation is available at https://www.keycloak.org/docs/4.8/server_admin/index.html#_mappers
Now your user in Keycloak will have attributes and roles you mapped from Auth0.
Next enable Authorization on your client. You can now define your resources, scopes, policies and permissions in it. See https://www.keycloak.org/docs/4.8/authorization_services/index.html
I have configured OpenLDAP with my keycloak, so that user management is taken care by LDAP. I have successfully sync the users from LDAP and I can see the user details in my List of users in Keycloak.I am using master realm only.
But when I try to generate token giving admin-cli client it gives this error.
Even the Authorization code flow it doesn't work.Tried to log in via keycloak UI it gives Invalid Credentials.
How can we use LDAP users for authentication in Keycloak ?
We are considering to use the keycloak as our SSO framework.
According to the keycloak documentation for multi-tenancy support the application server should hold all the keycloak.json authentication files, the way to acquire those files is from the keycloak admin, is there a way to get them dynamically via API ? or at least to get the realm public key ? we would like to avoid to manually add this file for each realm to the application server (to avoid downtime, etc).
Another multi-tenancy related question - according to the documentation the same clients should be created for each realm, so if I have 100 realms and 10 clients, I should define the same 10 clients 100 times ? is there an alternative ?
One of our flows is backend micro-service that should be authenticated against an application (defined as keycloak client), we would like to avoid keeping user/psw on the server for security reasons, is there a way that an admin can acquire a token and place it manually on the server file system for that micro service ? is there a option to generate this token in the keycloak UI ?
Thanks in advance.
All Keycloak functionality is available via the admin REST API, so you can automate this. The realm's public key is available via http://localhost:8080/auth/realms/{realm}/
A realm for each tenant will give a tenant-specific login page. Therefore this is the way to go - 10 clients registered 100 times. See more in the chapter Client Registration of the Keycloak documentation. If you don't need specific themes, you can opt to put everything in one realm, but you will lose a lot of flexibility on that path.
If your backend micro service should appear like one (technical) user, you can issue an offline token that doesn't expire. This is the online documentation for offline tokens. Currently there is no admin functionality to retrieve an offline token for a user by an admin. You'll need to build this yourself. An admin can later revoke offline tokens using the given admin API.
I am trying to integrate my client application with ServiceNow using OAuth 2.0 authentication. In servicenow documentation for REST apis i have seen that we have to register our client with servicenow to get clientid and clientsecret for OAuth 2.0 resource owner password authentication. In the document to register the application we have to navigate to System OAuth > Application Registry in servicenow, but in my servicenow instance System OAuth > Application Registry is not present. How should i proceed to get the clientid and clientsecret
It sounds like the OAuth 2.0 plugin may not be active on your instance.
Got to: https://YOURINSTANCE/v_plugin_list.do?sysparm_query=GOTOname%3E%3Doauth and make sure it is Active
Also in your System Properties, make sure that OAuth is turned on.
This URL: sys_properties_list.do?sysparm_query=GOTOname%3E%3Dcom.snc.platform.security.oauth.is.active
Also check out the wiki for any further clarification:
Good luck!
Steps to create and app and get client id/client secret.
Log into ServiceNow. Make sure you have an admin user login.
You need to navigate to System OAuth > Application Registry. Click New.
Easiest way is to search for "Application Registry"to register an OAuth client application in ServiceNow interceptor page, click Create an OAuth API endpoint for external clients. Fill out the fields, as appropriate.
Step 1
Step 2
Name - e.g. MyApp
If you leave the "Client Secret" as blank that will be the admin password by default (I won't recommend this)
Step 3
Additional Info:
Note that the refresh token expires in 100 days (8,640,000 seconds).
You can update the “Refresh Token Lifespan” to “2,147,483,647” (maximum value allowed by ServiceNow) to have a longer expiry for refreshtoken.

Make sure tables you access via the api are allowed for web service access. Go to System Definition > Tables and locate your table (e.g. “sys-user”). Make sure “Allow access to this table via web services” checkbox is ticked. By default this is enabled.
Provide your Servicenow admin account username and password with the ClientId and ClientSecret to authorise your app to connect to ServiceNow.
