Symptoms

  • DPC UI login fails with a 401 Unauthorized error.

  • The following errors appear in the IAM service log (/var/log/dpc/iam/iam-service/iam-services.log):

    • WebClientRequestException: finishConnect(..) failed: Connection refused: iam-provider:<IPv6>:8443
IAMExchangeException(errorMessage=Cannot get admin access token, httpStatus=401 UNAUTHORIZED)

Cause

The issue is caused by a password synchronization failure between the IAM service and the Keycloak identity provider.
This prevents the IAM service from obtaining the necessary admin access token, resulting in login failure.

Resolution

This issue requires intervention from Dell Support.
To resolve the problem:

  1. Do not attempt to restart services or modify IAM/Keycloak configurations manually.
  2. Open a service request with Dell Support and reference this KB Article (#000375379) to expedite the resolution.
