A marketplace app in Azure is installed as an app service. For claims based authentication to work the app requires the ADFS token-signing certificate be installed on Local Machine > Trusted People store. But there is no feature like that in Azure app service where I can install a certificate to a store (I'm not trying to change SSL settings of the app).
So I went to Advanced tools > Go (Kudu tools) in Azure app service and then Debug Console > Powershell. Here I issued this command
Import-Certificate -FilePath "D:\home\site\wwwroot\App_Data\website.cer" -CertStoreLocation "Cert:\LocalMachine\TrustedPeople" -Verbose
This threw an error
Import-Certificate : The Win32 internal error "The handle is invalid" 0x6 occurred while setting character attributes for the console output buffer.
How do I import this certificate in Azure so that the Marketplace app can access it? Not using IaaS.
EDIT 1: I tried Add-AzureCertificate cmdlet but it throws an error that Subscription is not selected. When I issue the Select-AzureSubscription with Subscription Id specified it says subscription does not exist.
EDIT 2: Tried connecting using Azure Rm cmdlet as suggested in comments. But still get same error - subscription does not exist. And if it cannot find subscription I cannot add the certificate using Import-Certificate
