When using Azure Key Vault management REST API or cmdlet Add-AzureRmKeyVaultNetworkRule to allow a virtual network to access a key vault, I get the following error:
The client '{guid}' with object id '{guid}' does not have authorization to perform
action 'microsoft.network/virtualnetworks/taggedTrafficConsumers/validate/action'
over scope '/subscriptions/{guid}/resourcegroups/{resource-group}/providers/microsoft.network/virtualnetworks/{vnet-name}/taggedTrafficConsumers/Microsoft.KeyVault'
What is wrong?
