Identity unable to connect to Keycloak (HTTP 403)

Camunda 8 Topics

Hello,

Here are the details:

1. What did you expect to happen? What did happen?

Expected: Identity to connect to Keycloak in order to create Camunda realm, firts “demo” user and apps (Operate and Zeebe) setup.
Happened: Identity unable to connect to Keycloak. Forbidden (HTTP 403)

I’ve verified the value of the admin password from the Keycloak secret and both the env vars for admin password in Identity (KEYCLOAK_SETUP_PASSWORD) and Keycloak (KEYCLOAK_ADMIN_PASSWORD) pods are the same.
I’ve set the “Require SSL” = None in the Keycloak master realm settings and restarted the Identity pod.

2. YAML configuration for Helm.

Here is an extract of my values.yaml file.

All other values are inherited from camunda-platform/values.yaml

IDENTITY_AUTH_PROVIDER_BACKEND_URL = "https://my-keycloak-service-fullname:80/auth/realms/camunda-platform"

KEYCLOAK_URL= "https://my-keycloak-service-fullname:80/auth"

What environment are you running C8 on?
Own servers and managed Open Shift cluster v4.12.

3. What version are you running?

V8.3.2 on a self-managed (no Optimize yet, no Tasklist), custom Open Shift routes (Keycloak, Identity, Operate, Zeebe gateway) instead of ingresses.
All pods are running but Identity (and Operate which makes sense I guess since it cannot authenticate to Zeebe without credentials)

4. Error logs or stack traces.

Thanks for your help!

UPDATE 1: I made progress thanks to this topic on manually disabling SSL in Keycloak. We don’t use the whitelisted IP ranges by Keycloak so SSL is required.

  1. Under “master” realm, setting “Require SSL” to “None” will allow creation of “camunda-platform” realm.
  2. Once created, under “camunda-platform” realm, setting “Require SSL” to “None” will allow creation of roles and “demo” user and Identity to eventually start.

Remaining issues:

  1. Manually disabling SSL is just a workaround but I’m yet to find a long term solution for production.
  2. Logging out in Operate or Identity won’t work.
  3. Logging in will redirect to http only: (e.g. my-operate-fullname-service.domain.tld/api/login) even though my Open Shift route specifies “insecureEdgeTerminationPolicy: Redirect”
  4. When connection token expires Identity will no longer be accessible and logs will show the following error: io.camunda.identity.sdk.impl.rest.exception.RestException: request failed with status code '400' and body '{"error":"invalid_grant","error_description":"Session not active"}'

Could you solve the problem? i’ve tried different versions of camunda 8.5.x, 8.4.x, 8.3.x and in all version i get the same issue:

io.camunda.identity.sdk.impl.rest.exception.RestException: request failed with status code ‘400’ and body ‘{“error”:“invalid_grant”,“error_description”:“Session not active”}’

I have mange to track down the error and it happends when the session of identity is active but somehow the session of tasklist have expired (even tho it should be the same) and then when i try to log in back to tasklist it gives me that error.
