It's not an option to create a client for each customer.
Currently we
have 65 000 customers, and we do not care if they use our API or using
us within their browser.
We want to just generate an offline token for a given user? Can
someone please tell me how to do it. I've read the documentation, but
it not clear for me how to obtain an offline token
(
http://keycloak.github.io/docs/userguide/keycloak-server/html/timeouts.ht...).
Not sure I understand all the details for your usecase. But the usecase
like "give me an offline token for this user for this app" can be done
with usage of direct grant. See here the docs for direct grant
http://keycloak.github.io/docs/userguide/keycloak-server/html/direct-acce...
. If you want to retrieve offline token through direct grant, you just
need to add the parameter "scope=offline_access" to the body of POST
methods. So instead of just:
username=bburke&password=geheim&grant_type=password
you will use:
username=bburke&password=geheim&grant_type=password&scope=offline_access
But note, that offline token is not a permanent token, which can be
unlimitedly used for authentication against REST backend services.
Offline token is just special kind of refresh token, which never
expires. You can use offline token to "refresh" and retrieve the access
token, which can itself be used for authentication against REST backend
services. But the access token has limited lifetime (usually 1 minute).
So typically once you retrieve offline token, you need to save it in the
database and always when you need to send request to REST backend, you
use offline token to retrieve access token and then use this access
token to send REST request. I suggest to take a look at
offline_access_app example in the demo.

Thanks in advance :-)

I would create a client for each customer. Enable the service
account feature to map roles to the client. Then customers can
authenticate either with a secret or signed jwt (public/private
key). They can then use the client credentials grant to obtain tokens.

Saw your session at JavaZone, so thought we could give KC a
try :-)
Our web application is split on two; frontend
(HTML5/Javascript) and our backend (REST lv. 3 developed in
Java, currently running inside Tomcat).
Our frontend is just a consumer of our backend API (just like
any other client), and I've successfully configured KC to use
openid-connect/public for our frontend with keycloak.js, and
openid-connect/bearer-only for our backend (API) in our test
environment (sending the Authorization header with Bearer
and keycloak.token to backend when doing ajax requests). This
work like expected. Even written our own federation doing
password validation from our user database.
But, a lot of our customers have integrated their application
to our backend API, doing REST calls for issuing invoices, etc...)
Most other services that provides you with an API offers
tokens that can be used for identification and authentication.
And as far as I can see, this is offline tokens in KC.
So we want to have our users log in to our service with their
browser, go to our "API key page" and create a new token to be
used by the integrations (moving away from Basic auth).
I've created an offline token by hitting a keycloak protected
html file and requested a resource with parameter
?scope=offline_access. I do see KC gives me a value back:
http://localhost/keycloak.html?scope=offline_access&code=HU5UkZ_EbNUj...
But there is no way I can use this for anything (and in KC it
seems to be bound to our frontend application).
Why can't I use the admin rest api to say something like: give
me an offline token for this user for this app?

Heisann,
Nice to see fellow Norwegians are using Keycloak :)
For offline tokens the idea is that you'd have a frontend
app (server or client, whichever floats your boat) that
can bootstrap the offline token.
Not sure offline tokens is quite what you need though -
can you elaborate a bit on your use case?

How can we generate an offline token for a given user

only)?
We have a lot of customers that is integrated to our
API (which is our backend client).
