No AuthenticationProvider found for org.springframework.security.authentication.UsernamePasswordAuthenticationToken

[WajahatAliAbid]

I am trying to integrate KeyCloak with ShinyProxy using openid authentication and I've provided the following configuration

proxy:
  authentication: openid
  openid:
    auth-url: http://localhost:8080/auth/realms/master/protocol/openid-connect/auth
    token-url: http://localhost:8080/auth/realms/master/protocol/openid-connect/token
    jwks-url: http://localhost:8080/auth/realms/master/protocol/openid-connect/certs
    userinfo-url: http://localhost:8080/auth/realms/master/protocol/openid-connect/userinfo
    client-id: shinyproxy
    client-secret: my-secret
    roles-claim: http://localhost:8080/auth/realms/master/protocol/openid-connect/userinfo
    logout-url: http://localhost:8080/auth/realms/master/protocol/openid-connect/logout

I've created a client shinyproxy on keycloak and added client secret for it in the above configuration. When I open shinyproxy, I get redirected to login endpoint for keycloak and after I provide credential information and click login, I get the following screen

Whereas in the logs, I see this

2023-10-03 22:46:58.435  INFO 1 --- [  XNIO-1 task-2] e.o.containerproxy.service.UserService   : Authentication failure [user: shinyproxy] [error: No AuthenticationProvider found for org.springframework.security.authentication.UsernamePasswordAuthenticationToken]

I am not sure what I am missing. I tried the authentication: keycloak and it works, but it doesn't let me logout the user. So I am trying to go with openid flow. Am I missing something here?

Hi

This seems to be a low-level error indicating that ShinyProxy did not receive a correct response for the request to the token token-url. Therefore can you check that the token-url is correct and that ShinyProxy can access the host? For example, make sure ShinyProxy can resolve the DNS hostname used in the token-url.

[tkolo]

I'll write this here for posterity as this was the first search result for me when looking for this issue:
In addition to issues with token endpoint, this error also happens when username-attribute is not available in identity token. By default it's set to email and shinyproxy will even sneakily append email to requested scopes to ensure it's present, however in case it's not the application will crash with this error.

[LEDfan]

Thanks @tkolo for reporting this, I'll check whether we can further improve the error handling.
