I have delegated access to Azure resources in a third-party tenant using Lighthouse, and this works fine via the portal; users receive the roles expected (typically Contributor).
However, they are unable to access Kudu (at webappname.scm.azurewebsites.net), receiving an error;
Selected user account does not exist in tenant 'Tenant Name' and cannot access the application 'abfa0a7c-a6b6-4736-8310-5855508787cd' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account.
If the same user account is added as a guest to the third-party tenant and given the same role, they can access Kudu as expected.
It's clear that Kudu is expecting/demanding an account in the same tenant as the application, but Azure Lighthouse delegated permissions is all about not having to do that.
Is there something I'm missing, another role that needs granting, or is Kudu just not compatible with Lighthouse-delegated permissions?
