The impersonation feature we have logs the admin in as the impersonated user rather than generate tokens. We decided on this approach as it would be transparent to applications and they wouldn't need to build-in special impersonation. What you want is not possible at the moment, but you can create a JIRA feature request for it. It would have to be a community contribution if you want it added in a timely manner.

I need a help with user impersonation on keycloak.


I am authenticating users through the "/realms/test/protocol/openid-connect/token". As expected, it returns a token JWT.

In my app, all requests go through apiman, which validates the JWT.


Now, I need to personification of user. I'm calling the service "/admin/realms/test/users/USER_ID/impersonation", sending the token in the header (Authorization = Bearer eyJhbGciOiJSUzI1NiJ9 ...).

The service /impersonation creates the user session on keycloak, however doesnt return a JWT, but 3 cookies. I'd like to get the JWT of personified user instead of cookie. It's possible?
