If policy is set and either policy.allowedCIDRs[] or policy.rejectedCIDRs[] is set, the following rules apply: If allowedCIDRs[] and rejectedCIDRs[] are both set, then rejectedCIDRs[] has precedence over allowedCIDRs[]. First, log into Azure:- 1 az login Then get the clientId of your cluster: - 1 az aks show --resource-group RESOURCEGROUPNAME --name CLUSTERNAME --query "servicePrincipalProfile.clientId" --output tsv To confirm that the principal is expired: - 1 az ad sp credential list --id CLIENTID Check the endDate value highlighted above.
