Jenkins and plugins versions report

Environment

Paste the output here

What Operating System are you using (both controller, and any agents involved in the problem)?

The plugins are being used to get secrets from the KeyVault on a Jenkins that is in an AKS.

To log into azure with a Managed Identity we are using the new Workload Identity feature (https://learn.microsoft.com/en-us/azure/aks/workload-identity-overview) for kubernetes.

Previously we were using Pod Identity to get the secrets and it usually took about 30s to get the secret but since using the new feature, getting secrets has been taking about 15 minutes.

Version list:
Jenkins: 2.361.4
Azure Keyvault plugin: 143.v73ce6f5bcdbc
Kubernetes: 1.23

Reproduction steps

1. az login --identity
2. Use plugin to obtain secrets from keyvault

Expected Results

Expected time less than 30s

Actual Results

Times of up to 10 minutes can be obtained

Anything else?

No response

Err it should retrieve a secret in less than a second.

I don't have an environment setup to reproduce this currently but when I get a chance I'll have a look.
