One requirement is that the certificate must be configured with one or more purposes in Extended Key Usage EKU extensions that match the certificate use. For example, a certificate that is used for the authentication of a client to a server must be configured with the Client Authentication purpose.
Or, a certificate that is used for the authentication of a server must be configured with the Server Authentication purpose. When certificates are used for authentication, the authenticator examines the client certificate and looks for the correct purpose object identifier in EKU extensions. For example, the object identifier for the Client Authentication purpose is 1.
Minimum certificate requirements All certificates that are used for network access authentication must meet the requirements for X. After these minimum requirements are met, both the client certificates and the server certificates must meet the following additional requirements. The user or the computer certificate on the client chains to a trusted root CA.
The user or the computer certificate on the client includes the Client Authentication purpose. The user or the computer certificate does not fail any one of the checks that are performed by the CryptoAPI certificate store, and the certificate passes requirements in the remote access policy. The user or the computer certificate does not fail any one of the certificate object identifier checks that are specified in the Internet Authentication Service IAS remote access policy.
The Wireless clients and virtual private network VPN clients do not display certificates that are protected with a password. Certificates that do not contain the Client Authentication purpose in EKU extensions are not displayed. Server certificate requirements You can configure clients to validate server certificates by using the Validate server certificate option on the Authentication tab in the Network Connection properties.

Australia - English.Network administrators often require authentication and authorization of users or devices attaching to their networks. For example, a network administrator can require that only known users be allowed to connect.
Likewise, the operator of a virtual private network VPN can require that remote network access only be granted to known and authorized users. EAP enables extensible authentication for network access. EAP methods operate within the EAP framework to provide support for a variety of authentication techniques. Strong credentials, such as digital certificatesoffer many security benefits. However, in many environments, deploying such credentials to every client can be expensive and hard to manage due to the infrastructure they require.
This, for example, is often the case for corporate wireless network deployments. As a result, there is a need for an EAP method that can provide the security benefits of authentication with strong credentials, without incurring the cost of an infrastructure required by a client public key infrastructure PKI deployment.
It does so by having the client establish a TLS session with a server by using the server's certificate. Then, the client is authenticated using its credential of choice within that TLS session. PEAP and version 0 are selected. PEAP enters phase 1.
This completes phase 1. This completes phase 2. The security provided by the TLS session established in phase 1 protects the PEAP peer authentication in phase 2 so that passwords or other dictionary-attackable tokens can be used confidentially. PEAP is typically deployed in an environment such as the one depicted in the following figure. Skip to main content. Exit focus mode. PEAP completes when phase 2 is completed.

Appears as Smart Card or other Certificate Properties in the operating system. For configuration details, see Smart Card or other Certificate Properties configuration items.
EAP authentication methods that are used within tunneled EAP methods are commonly known as inner methods, and they are also referred to as EAP types in some documentation. This section about Smart Card or other Certificate Properties includes information about the following configurations:. Enables authentication by using SIM cards, and is implemented when a customer purchases a wireless broadband service plan from a mobile network operator.
Certificate requirements when you use EAP-TLS or PEAP with EAP-TLS
As part of the plan, the customer commonly receives a wireless profile that is preconfigured for SIM authentication. You can access the EAP properties for By default, you can configure EAP settings for the following network authentication methods for Specifies that the client verifies that server certificates presented to the client computer have the correct signatures, have not expired, and were issued by a trusted root certification authority CA.
If you disable this check box, client computers cannot verify the identity of your servers during the authentication process. If server authentication does not occur, users are exposed to severe security risks, including the possibility that users might unknowingly connect to a rogue network. You must type the name exactly as it appears in the Subject field of each RADIUS server certificate, or use regular expressions to specify the server name.
For example, you can specify nps. Lists the trusted root certification authorities. The list of trusted root certification authorities is built from the trusted root CAs that are installed in the computer and in the user certificate stores. You can specify which trusted root CA certificates supplicants use to determine whether they trust your servers, such as your server running Network Policy Server NPS or your provisioning server.
If no trusted root CAs are selected, the If one or multiple trusted root CAs are selected, the You can also purchase a CA certificate from a non-Microsoft vendor. Some non-Microsoft trusted root CAs provide software with your purchased certificate that automatically installs the purchased certificate into the Trusted Root Certification Authorities certificate store. In this case, the trusted root CA automatically appears in the list of trusted root CAs.
If you designate a certificate that is not installed on client computers, authentication will fail. Case 1: Do not ask user to authorize new servers or trusted CAs specifies that if:.
Case 2: Tell user if the server name or root certificate is not specified specifies that if:. If the user accepts the certificate, authentication proceeds. If the user rejects the certificate, the connection attempt fails. In this option, if the root certificate is not present on the computer, the user is not notified and the connection attempts fails. However, EAP is a flexible protocol that allows inclusion of additional EAP methods, and it is not restricted to these two types.
Enables the ability to create a new or refreshed security association more efficiently or in a smaller number of round- trips, in the case where a security association was previously established. Users who connect by using wireless mobile broadband will benefit most from this capability.
An example of this benefit is a common scenario in which a user is traveling on a train, uses a wireless mobile broadband card to connect to the Internet, and then establishes a VPN connection to the corporate network.
As the train passes through a tunnel, the Internet connection is lost. When the train is outside the tunnel, the wireless mobile broadband card automatically reconnects to the Internet.
The user must repeat the multistep process to connect to the VPN each time Internet connectivity is interrupted.In this step, you'll learn about the ProfileXML options and schema, and configure the Windows 10 client computers to communicate with that infrastructure with a VPN connection. Automating PowerShell enrollment for organizations without Configuration Manager or Intune is possible. However, you can use logon scripts.
Below you find each of the required settings and its corresponding ProfileXML tag. You configure each setting in a specific tag within the ProfileXML schema, and not all of them are found under the native profile. For additional tag placement, see the ProfileXML schema. Any other combination of upper or lower case for 'true' in the following tags results in a partial configuration of the VPN profile:.
You can use simple tags to configure some VPN authentication mechanisms. Before creating the template, take note the hostname or fully qualified domain name FQDN of the NPS server from the server's certificate and the name of the CA that issued the certificate. You use these values in the upcoming VPN template configuration. For example, if the server's FQDN is nps If you have multiple NPS servers, complete these steps on each one so that the VPN profile can verify each of them should they be used.
Now that you have the necessary information configure the template VPN profile on a domain-joined client computer. The type of user account you use that is, standard user or administrator for this part of the process does not matter.
However, if you haven't restarted the computer since configuring certificate autoenrollment, do so before configuring the template VPN connection to ensure you have a usable certificate enrolled on it. The server name you type must match the name in the certificate.
You recovered this name earlier in this section. In Notifications before connecting, click Don't ask user to authorize new servers or trusted CAs. The Smart Card or other Certificate Properties dialog opens. In the Connect to these servers box, enter the name of the NPS server you retrieved from the NPS server authentication settings in the previous steps.
Select the Don't prompt user to authorize new servers or trusted certification authorities check box. Doing so ensures that the EAP settings are correct before you use them in the next example. You must connect at least once before continuing; otherwise, the profile will not contain all the information necessary to connect to the VPN. Before completing this section, make sure you have created and tested the template VPN connection that the section Manually create a template connection profile describes.
Testing the VPN connection is necessary to ensure that the profile contains all the information required to connect to the VPN. The Windows PowerShell script in Listing 1 creates two files on the desktop, both of which contain EAPConfiguration tags based on the template connection profile you created previously:.
You cannot run this script in a Remote Desktop session, including a Hyper-V enhanced session. Sign in to the domain-joined client computer containing the template VPN profile with the same user account that the section Manually create a template connection profile described. A full description of each setting is in the comments. To view the full example script, see the section MakeProfile.
The name of the template from which to retrieve the EAP configuration. Unique alphanumeric identifier for the profile. If the profile name has a space or other non-alphanumeric character, it must be properly escaped according to the URL encoding standard.Both client and server certificates have additional requirements. This topic provides instructions for configuring certificate templates.
Client computers can be configured to validate server certificates by using the Validate server certificate option on the client computer or in Group Policy. The client computer accepts the authentication attempt of the server when the server certificate meets the following requirements:. The Subject name contains a value. To configure the certificate template with a Subject name:. The computer certificate on the server chains to a trusted root certification authority CA and does not fail any of the checks that are performed by CryptoAPI and that are specified in the remote access policy or network policy.
The object identifier for Server Authentication is 1. Certificates that do not contain the Server Authentication purpose in EKU extensions are not displayed. For more information, see Deploy Server Certificates for The user or computer certificate on the client chains to a trusted root CA, includes the Client Authentication purpose in EKU extensions the object identifier for Client Authentication is 1.
The To configure the UPN in a certificate template:. To configure this name in the certificate template:. Certificates that do not contain the Client Authentication purpose in EKU extensions are not displayed.

These can be fake since it does not impact the authentication parameters.
From the drop-down menu, select the EAP method that you want to configure, and then select Properties to configure as needed. In your deployment, if you have multiple certificates provisioned on the device and the Wi-Fi profile provisioned does not have a strict filtering criteria, you might see connection failures when connecting to Wi-Fi.
The solution is to ensure that the Wi-Fi profile provisioned has strict filtering criteria so that it matches only one certificate. Enterprises deploying certificate-based EAP authentication for VPN and Wi-Fi can encounter a situation where there are multiple certificates that meet the default criteria for authentication. This can lead to issues such as:.
A production ready deployment must have the appropriate certificate details as part of the profile being deployed. The following information explains how to create or update an EAP configuration XML such that the extraneous certificates are filtered out and the appropriate certificate can be used for the authentication.
This can be done manually by editing the following XML sample, or by using the step-by-step UI guide. The user or the computer certificate does not fail any one of the checks that are performed by the CryptoAPI certificate store, and the certificate passes requirements in the remote access policy.
