- May 22, 2020 Wireless bootstrap profiles are temporary profiles that are configured in such a way as to enable wireless client users to connect to the 802.1X-authenticated wireless network before the computer is joined to the domain, and/or before the user has successfully logged on to the domain by using a given wireless computer for the first time.
- 802.1X Authentication for Windows Client without Server Certificate By default, 802.1X authentication on Window 7, Window 8.1, and Window 10 consists of not only client authentication but also server authentication, which requires the server (here is the VigorAP) to provide certificate information to.

| The supplicant, or client, is the device attempting to gain access to the network. You can configure the Aruba user-centric network to support 802.1x authentication for wired users as well as wireless users. |
| The authenticator is the gatekeeper to the network and permits or denies access to the supplicants. |
| The Arubacontroller acts as the authenticator, relaying information between the authentication server and supplicant. The EAP type must be consistent between the authentication server and supplicant and is transparent to the controller. |

802.1x Client Certificate
The 802.1X authentication server is typically an EAP-compliant Remote Access Dial-In User Service (RADIUS) server which can authenticate either users (through passwords or certificates) or the client computer.
An example of an 802.1X authentication server is the Internet Authentication Service (IAS) in Windows (see http://technet.microsoft.com/en-us/library/cc759077(WS.10).aspx).
Aruba user-centric networks, you can terminate the 802.1x authentication on the controller. The controller passes user authentication to its internal database or to a “backend” non-802.1X server. This feature, also called AAA FastConnect, is useful for deployments where an 802.1X EAP-compliant RADIUS server is not available or required for authentication.
Supported EAP Types
The following is the list of supported EAP types.
| PEAP—Protected EAP (PEAP) is an 802.1X authentication method that uses server-side public key certificates to authenticate clients with server. The PEAP authentication creates an encrypted SSL / TLS tunnel between the client and the authentication server. The exchange of information is encrypted and stored in the tunnel ensuring the user credentials are kept secure. |
| EAP-GTC—The EAP-GTC (Generic Token Card) type uses clear text method to exchange authentication controls between client and server. Since the authentication mechanism uses the one-time tokens (generated by the card), this method of credential exchange is considered safe. In addition, EAP-GTC is used in PEAP or TTLS tunnels in wireless environments. The EAP-GTC is described in RFC 2284. |
| EAP-AKA—The EAP-AKA (Authentication and Key Agreement) authentication mechanism is typically used in mobile networks that include Universal Mobile Telecommunication Systems (UMTS) and CDMA 2000. This method uses the information stored in the Subscriber Identity Module (SIM) for authentication. The EAP-AKA is described in RFC 4187. |
| EAP-FAST—The EAP-FAST (Flexible Authentication via Secure Tunneling) is an alternative authentication method to PEAP. This method uses the Protected Access Credential (PAC) for verifying clients on the network. The EAP-FAST is described in RFC 4851. |
| EAP-MD5—The EAP-MD5 method verifies MD5 hash of a user password for authentication. This method is commonly used in a trusted network. The EAP-MD5 is described in RFC 2284. |
| EAP-POTP—The EAP type 32 is supported. Complete details are described in RFC 4793. |
| EAP-SIM—The EAP-SIM (Subscriber Identity Module) uses Global System for Mobile Communication (GSM) Subscriber Identity Module (SIM) for authentication and session key distribution. This authentication mechanism includes network authentication, user anonymity support, result indication, and fast re-authentication procedure. Complete details about this authentication mechanism is described in RFC 4186. |
| EAP-TLS—The EAP-TLS (Transport Layer Security) uses Public key Infrastructure (PKI) to set up authentication with a RADIUS server or any authentication server. This method requires the use of a client-side certificate for communicating with the authentication server. The EAP-TLS is described in RFC 5216. |
| EAP-TLV- The EAP-TLV (type-length-value) method allows you to add additional information in an EAP message. Often this method is used to provide more information about a EAP message. For example, status information or authorization data. This method is always used after a typical EAP authentication process. |
| EAP-TTLS—The EAP-TTLS (Tunneled Transport Layer Security) method uses server-side certificates to set up authentication between clients and servers. The actually authentication is, however, performed using passwords. Complete details about EAP-TTLS is described in RFC 5281. |
| LEAP—Lightweight Extensible Authentication Protocol (LEAP) uses dynamic WEP keys and mutual authentication between client and RADIUS server. |
| ZLXEAP—This is Zonelabs EAP. For more information, visit http://tools.ietf.org/html/draft-bersani-eap-synthesis-sharedkeymethods-00#page-30. |
Configuring Authentication with a RADIUS Server
See Table 1 for an overview of the parameters that you need to configure on authentication components when the authentication server is an 802.1X EAP-compliant RADIUS server.
Figure 1 802.1X Authentication with RADIUS Server
The supplicant and authentication server must be configured to use the same EAP type. The controller does not need to know the EAP type used between the supplicant and authentication server.
For the controller to communicate with the authentication server, you must configure the IP address, authentication port, and accounting port of the server on the controller. The authentication server must be configured with the IP address of the RADIUS client, which is the controller in this case. Both the controller and the authentication server must be configured to use the same shared secret.
Additional information on EAP types supported in a Windows environment, Microsoft supplicants, and authentication server, is available at http://technet.microsoft.com/en-us/library/cc782851(WS.10).aspx. |
The client communicates with the controller through a GRE tunnel in order to form an association with an AP and to authenticate to the network. Therefore, the network authentication and encryption configured for an ESSID must be the same on both the client and the controller.
Configuring Authentication Terminated on Controller
User authentication is performed either via the controller’s internal database or a non-802.1X server. See 802.1x Authentication Profile Basic WebUI Parameters for an overview of the parameters that you need to configure on 802.1X authentication components when 802.1X authentication is terminated on the controller (AAA FastConnect).
In this scenario, the supplicant is configured for EAP-Transport Layer Security (TLS) or EAP-Protected EAP (PEAP).
| EAP-TLS is used with smart card user authentication. A smart card holds a digital certificate which, with the user-entered personal identification number (PIN), allows the user to be authenticated on the network. EAP-TLS relies on digital certificates to verify the identities of both the client and server. |
EAP-TLS requires that you import server and certification authority (CA) certificates onto the controller (see Configuring and Using Certificates with AAA FastConnect). The client certificate is verified on the controller (the client certificate must be signed by a known CA) before the user name is checked on the authentication server.
| EAP-PEAP uses TLS to create an encrypted tunnel. Within the tunnel, one of the following “inner EAP” methods is used: |
| EAP-Generic Token Card (GTC): Described in RFC 2284, this EAP method permits the transfer of unencrypted usernames and passwords from client to server. The main uses for EAP-GTC are one-time token cards such as SecureID and the use of an LDAP or RADIUS server as the user authentication server. You can also enable caching of user credentials on the controller as a backup to an external authentication server. |
| EAP-Microsoft Challenge Handshake Authentication Protocol version 2 (MS-CHAPv2): Described in RFC 2759, this EAP method is widely supported by Microsoft clients. A RADIUS server must be used as the backend authentication server. |
If you are using the controller’s internal database for user authentication, you need to add the names and passwords of the users to be authenticated. If you are using an LDAP server for user authentication, you need to configure the LDAP server on the controller, and configure user IDs and passwords. If you are using a RADIUS server for user authentication, you need to configure the RADIUS server on the controller.
Cisco Ise 802.1x Certificate Authentication
Hello,
I am using my MBP for work and want to connected to my work's network.
We are using 802.1x network authentication, based on a computer certificate. I joined my computer to our Microsoft Active Directory and created a computer certificate, which I imported successfully to 'System' store.
Free software download for apple macbook pro os x 10.10.
Only 'Error description' is, that my MBP tries to authenticate as 'User'.
How do I configure my network settings, to use 'computer-based authentication' and use the computer certificate?
