Hi,
I found no possibility to do it via the GUI. So I accessed the file system directly and installed in "/data/misc/wifi" the necessary certificate file and added in "/data/misc/wifi/wpa_supplicant.conf":
network={
ssid="eduroam"
key_mgmt=WPA-EAP
eap=TTLS
proto=WPA
identity="YourNameHere"
anonymous_identity="anonymous@cms.hu-berlin.de"
password="YourPasswordHere"
ca_cert="/data/misc/wifi/deutsche-telekom-root-ca-2.crt"
phase2="auth=PAP"
}
It hopes that helps someone
