ADFS error - The audience restriction was not valid because the specified audience identifier is not present in the acceptable identifiers list of this Federation Service.

After adding a claims provider trust in ADFS, we got the following error message when trying to use the configured 3th party IP-STS.

The audience restriction was not valid because the specified audience identifier is not present in the acceptable identifiers list of this Federation Service.

User Action

See the exception details for the audience identifier that failed validation. If the audience identifier identifies this Federation Service, add the audience identifier to the acceptable identifiers list by using Windows PowerShell for AD FS.  Note that the audience identifier is used to verify whether the token was sent to this Federation Service. If you think that the audience identifier does not identify your Federation Service, adding it to the acceptable identifiers list may open a security vulnerability in your system.

Exception details:

Microsoft.IdentityServer.AuthenticationFailedException: ID1038: The AudienceRestrictionCondition was not valid because the specified Audience is not present in AudienceUris.

Audience: 'http://adfs4.example.be/adfs/services/trust' ---> Microsoft.IdentityModel.Tokens.AudienceUriValidationFailedException: ID1038: The AudienceRestrictionCondition was not valid because the specified Audience is not present in AudienceUris.

Audience: 'http://adfs4.example.be/adfs/services/trust'

To solve this problem we had to add the audience uri of our ADFS server to the list of acceptable identifiers(as well explained in the error message):

 set-ADFSProperties -AcceptableIdentifier 'http://adfs4.example.be/adfs/services/trust'

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...
