title: Azure Data Factory Linked Service error- Failed to get the secret from key vault
body: <p>I am creating a linked service to a remote server in Azure Data Factory v2. The remote server uses username-password authentication mechanism. I have already created a linked service to the same server using username and password both in the linked service creation window and its working fine. I would like to store the password as a secret in Azure Key vault and access that secret from Azure Data Factory.</p>
  
  <p>I have the secret in Azure Key vault and i have granted the access permission to Azure Data Factory to access Azure Key Vault by adding the Access policy in Key vault. I created linked service to azure key vault and it shows 'connection successful' when i tested the connection. However, when i try to create the linked service to a remote server using Azure key vault credentials instead of password, the connection failed. The error looks like this:</p>
  
  <p>Failed to get the secret from key vault, secretName: *********, secretVersion: , vaultBaseUrl:*****************. The error message is: An error occurred while sending the request. The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. The remote certificate is invalid according to the validation procedure.</p>
  
  <p>I couldn't proceed further. Any help/suggestions would be appreciated. </p>
