from Windows 802.1X connection instructions to linux

Was looking for PEAP tutorials for raspbian but didn't found any solution so far. In our manual for the LAN-connection to our network are following steps: 1. Activate IEEE 802.1X-authentification 2. Set Userauthentification as authentification-mode 3. Uncheck the option to check the identity of the server through Certificate 4. Select EAP-MSCHAP-V2 as authentification-method 5. Proceed and enter credentials: domainxxx\usernamexxx passwordxxx How can I reproduce these steps for raspbian? Edit (efforts so far): etc/wpa_supplicant/wpa_supplicant.conf: ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 network={ key_mgmt=IEEE8021X eap=PEAP identity="domainxxx\usernamexxx" password="passwordxxx" phase1="peaplabel=0" phase2="auth=MSCHAPV2" } edited the line "iface eth0 inet manual" from /etc/network/interfaces to: iface eth0 inet dhcp Currently following error: `eth0: CTRL-EVENT-EAP-STARTED EAP authentication started eth0: CTRL-EVENT-EAP-PROPOSED-METHOD vendor=0 method=25 eth0: CTRL-EVENT-EAP-METHOD EAP vendor 0 method 25 (PEAP) selected eth0: CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/DC=de/DC=MyDcxxxx/DC=domainxxx/CN=CNxxx' eth0: CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/DC=de/DC=MyDcxxxx/DC=domainxxx/CN=CNxxx' eth0: CTRL-EVENT-EAP-PEER-CERT depth=0 subject='/DC=de/DC=MyDcxxxx/DC=domainxxx/CN=CNxxx' SSL: SSL3 alert: write (local SSL3 detected an error):fatal:decrypt error OpenSSL: openssl_handshake - SSL_connect error:04091068:rsa routines:INT_RSA_VERIFY:bad signature OpenSSL: pending error: error:1408D07B:SSL routines:SSL3_GET_KEY_EXCHANGE:bad signature eth0: CTRL-EVENT-EAP-FAILURE EAP authentication failed` Distro is Raspbian.
