hybrid configuration of azure active directory (AzureAD)

Example:

1. Azure HDInsight cluster on a virtual network.

Plan: 

to allow users to authenticate to the cluster by using their on-premises Active Directory credentials.

Aim:

you need to configure the environment to support the planned authentication.

Solution and steps:

1. Instead, you connect HDInsight to your on-premises network by using Azure Virtual Networks and a VPN gateway.

Note: 

To allow HDInsight and resources in the joined network to communicate by name, you must perform the following actions.

1. Create Azure Virtual Network.
2. Create a custom DNS server in the Azure Virtual Network.
3. Configure the virtual network to use the custom DNS server instead of the default Azure Recursive Resolver.
4. Configure forwarding b/w the custom DNS server and your on-premises DNS server.
