Introduction
This blog will help you set Azure Active Directory level authentication to access Point-to-Site VPN from the user’s machine. It adds a level of security to your Azure infrastructure. The tunnel type should be Open VPN(SSL) to create the AAD authentication. This solution is helpful for end-users who want to connect to Azure VNets centers from a remote location, such as from home or a conference. You can also keep track of all the connections made to Azure VNet using P2S VPN with the help Azure Virtual Network gateway.

- Provide appropriate tags for the resources. Now click on click + Create and then click on Review + create.
Configuring AAD Authentication
- Log in to the Azure portal as a user assigned the Global administrator access.
- Go To Azure Active Directory Service. Under Properties, the page got to Tenant ID and copy it as shown in the below screenshot.
- Next, Copy and paste the below URL in the browser the below URL is for Azure Public and add the Azure VPN application to your AAD https://login.microsoftonline.com/common/oauth2/authorize?client_id=41b23e61-6c1e-4545-b367-cd054e0ed4b4&response_type=code&redirect_uri=https://portal.azure.com&nonce=1234&prompt=admin_consent

Next, select Azure Active Directory as the Authentication type, then provide the below information under the Azure Active Directory section.
- Tenant: https://login.microsoftonline.com/{AzureAD TenantID}/

- After that select your Azure AD account and click on Continue
- Once it gets connected successfully the icon will turn green and display connected
- You can now check that your machine will receive IP from the Point-to-Site Address poll
- Now you can RDP into the Azure VM using VMs Private IP for me it is 10.2.1.4
Conclusion
A VPN connection establishes a secure connection between you and the internet. A P2S connection is established by starting it from the client’s computer. With the help of Azure Active Directory (AAD) security benefits, you can centrally create and manage users across your hybrid enterprise, keeping users, groups, and devices synchronized.
