== Windows 7 ==
 
 
Windows 7 does not support EAP-TTLS / PAP from scratch. The same is true for eduroam networks and this is why there are a lot of instructions from universities which use SecureW2 as an additional Software to enable EAP-TTLS:
 
 
* https://www.cms.hu-berlin.de/de/dl/netze/wlan/config/eduroam/win7/eduroam-win7-securew2.pdf
 
 
Unfortunately, SecureW2 is not free (it used to be, but they revoked that).
 
 
Another option could be XSupplicant from the [http://open1x.sourceforge.net/ Open1X project]; they were working towards Windows 7 support, but it seems that they didn't make it. (Latest news is from 25 Sept 2010 that
 
version 2.2.2 should support it; I tried v2.2.2.504.x64, didn't work).
 
 
To summarize, right now we do not know a free option to connect with EAP-TTLS / PAP under Windows 7.

We're moving our wifi infrastructure to an authenticated and encrypted ssid. At the moment it's hard to change our internal wifi password, because our door system depends on it. If you are not in our internal wifi you can't operate the door.

This is one reason why we want to use 802.1x with EAP-TTLS. Every member has it's own username/password combination which can be reset or changed through a webinterface. If a member quits the space, we just have to deactivate the account and the internal access is gone.

The other reason is: Every member has its own encrypted channel to our access points. In addition the member has the possibility to check, if the SSID can be trusted (avoid roque APs) with an ssl certificate

certificate

To check if you're connecting to the correct SSID, you can and should add the ssl certificate to your connection setting. You can download the SSL CA-Certificate (ZIP-File) from our Server.

netctl

Save config as /etc/netctl/$interfacename-backspace_8021x. You have to restart netctl-auto (e.g. systemctl restart netctl-auto@$interface)

Description='backspace WPA2 802.1X'
Interface=wlp3s0
Connection=wireless
Security=wpa-configsection
IP=dhcp
ESSID="backspace 802.1x"

    'phase2="auth=PAP"'
)

FYI: Replace the interface name according to your system

wpa_supplicant

Add to /etc/wpa_supplicant/wpa_supplicant.conf:

network={

 key_mgmt=WPA-EAP
 eap=TTLS

 password="YOUR_PASSWORD"

Android

This is how you can connect with the android operating system to our 802.1x WIFI (WPA2 Enterprise)

  • Download our certificate (see top)
  • Open downloaded certificate
  • Save certificate as backspace.crt and type "Wifi"
  • Modify/Configure your backspace 802.1x connection according to the screenshot below
  • Attention: Some newer Android versions require a domain name if you use the certificate. Use radius.core.bckspc.de
  • Firefox on android might fail to import the certificate, stating that the certificate authority is already trusted. In these cases, chrome can stil import the certificate.

macOS and iOS

A ready profile file can be downloaded here (you need to provide your LDAP credentials when asked). You don't need to follow the other steps if you use this file. Note: For iOS you need to extract this ZIP file and send it to you phone (e.g. via email).


The following procedure has been tested using macOS 10.11 El Capitan to macOS 10.14 Mojave.

Earlier versions of macOS offered to specify the authentication protocol when connecting to a wireless network. However, in newer versions you'll have to install a configuration profile in order to connect to our network using 802.1X with EAP-TTLS/PAP. This configuration profile contains our certificate and all required settings.

It is fairly easy to generate a configuration file for your devices yourself with the added bonus of already including your username and password. This file can be used for all your Macs and iOS devices.

To generate the config file you need to download the Apple Configurator from the Mac App Store. [1]

Start the Configurator and choose File -> New Profile

In the General tab give the profile a name.

Then go down to Wi-Fi and configure the Payload:

SSID: backspace 802.1x
Security: Enterprise WPA2
EAP-TTLS
you can add your username and password here
Inner Authentification: PAP

Choose Save from the File menu and give the profile a name.

You can now install the profile on your Mac. (The installation only seems to work, if you have installed the Certificate under "Certificates" in the Configurator. But you must not click the certificate under "Trust" in the Wi-Fi payload, because that will fail the authentification. See below for trusting the RADIUS server.)

To install the file on your iOS device, simply connect the device to the laptop running Configurator via USB and drag the profile file onto the device when it shows up in the application.

Alternatively you can send the file to yourself via email. Tap the file in the Mail app and install it on your iOS device. WARNING: This will likely send your credentials unencrypted through the internet!

When installing your profiles the systems will tell you that the certificate is not signed and that you need to trust the RADIUS server. You just need to accept both and are ready.

Windows 8 and above

Since Windows 8 the system itself is capable of EAP-TTLS.
