The images of the 2 keycloak clients are as follows :

I have configured the js-report-studio client mappers as mentioned in the previous post but still I am getting Error: Authentication with authorization server failed. Information returned by the authorization server does not contain "username" field. Authentication cancelled message. I cannot even see the username in the access token. Can you show me the headers called to generate the access token that you showed in the sample?

Hi @AlexGoris-KasparSolutions I have followed the steps that you mentioned above. I just have a couple of doubts -

• Should the 'username' property be added to extensions_authentication_authorizationServer_studioClient_clientId: only and not to extensions_authentication_authorizationServer_apiResource_clientId: too because I need to use jsreports using both the studio and the API.

• How to find out the username that exists in jsreports that need to be provided to keycloak during login? I have added a user with permission to read and edit all entities in jsreport that exists in keycloak, does anything more need to be done?

• When I try to login using the username and password of the user mentioned in the previous point, I am getting Error: Authentication with authorization server failed. Information returned by the authorization server does not contain "username" field. Authentication cancelled message. My keycloak is running on a global IP through a docker container while the jsreport code is running on localhost. Is it not working for this reason?

Hi,
I am trying to configure jsreports to authenticate using Keycloak. I have come across authentication documentation and followed the jsreport configuration as mentioned in configuration example here.
I am still seeing request headers as Authorization Basic and not Bearer. I would like to receive some help in case any corresponding keycloak or other config related changes need to be made. Thank you.

Hi @AlexGoris-KasparSolutions can you please share the config file of jsreports that are working for you with Keycloak authorization? Also did you have to make any additions in Keycloak to make it work?
I am working on a similar thing and I am not getting any leads that work successfully. Please can you help me out?
