Angular OIDC - Avoid token sharing

To integrate OIDC in our Angular applications we are using the great angular-oauth2-oidc library from Manfred Steyer.

Once we receive a valid token back from our IdentityServer instance it is stored inside the session storage using the OAuthStorage class. This all seemed to work fine. However we got into trouble when we started to switch between applications. Different Angular apps were receiving a token from another app which resulted into errors.

The problem had nothing to do with the angular-oauth2-oidc library but with the way we had setup our applications. All our applications where sharing the same root url and were hosted as virtual directories inside IIS;

  • apps.example.com/app1
  • apps.example.com/app2
  • apps.example.com/app3

Session storage is scoped per domain but as all applications were using the same domain, they accidently accessed each other tokens.

To fix it we had to create our own OAuthStorage class that used an application prefix to isolate the tokens:

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t
