This document appears to imply that an AKS cluster can only have 20 federated identities per AKS cluster, is that correct?

https://learn.microsoft.com/en-us/azure/aks/workload-identity-overview#limitations

Or, based on the document you linked above can we have as many managed identities as we like federated into AKS, but each of them can only have 20 federated credentials attached?

Thanks

It's 20 federated credentials per Azure AD App/managed identity.

Great, thank you!

Hi @aramase We have the following question about this limitation:
For now, we have multi(more than 20) namespaces in aks. Within all of these namespaces, we need to access Azure Resources. However, we hope to only aissgn credential in single 3rd party app. we don't want to create multi 3rd party app.
How can we achieve it?

@pockyhe If you need to use the identity with more than 20 federated identity credentials, it is not possible because of this limitation. You'll need to create another identity.

In the future, this could be supported with wildcards in federated identity credential. Could you add your scenario and details to this issue. This is a growing list of set up and requirements, that the AAD team is looking at as part of supporting wildcards.

Hi, the wildcard feature is delayed for 2 years already, can you please increase the limit to 200?

[MoussaBangre]

Please increase this to 200. I do not really understand the reason of this limitation

Is there an update on whether this limit will be increased? 20 seems awfully low.
