Description of problem:
Connection to EDUROAM site still failing. This is an WPA2 enterprise site. Looks like there are auth problems, but my password is OK.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. try to connect to an WPA2 enterpries network
Logs are attached.
I am not sure, if this is a bug of wap_supplicant, NetworkManager or other component.
Worked well before upgrade to Fedora 21. On Fedora 21 unable to connect to these networks, but able to connect to other WPA PSK networks.
I am able to connect to WPA2 enterprise networks just fine. Though I didn't try with eduroam (I am gonna test it when I approach a network).
According to the logs, association with AP timed out. wpa_supplicant log in debug mode might reveal more.
Has anything else changed, such as your EDUROAM configuration, Wi-Fi card, place you connect from, etc?
Thank you. Something is wrong with openssl:

Downgrade openssl from Fedora 20 helped me to connect to this network.
Switching component to openssl.
Working version of openssl: 1:openssl-1.0.1e-40.fc20.x86_64
Wrong version of openssl: 1:openssl-1.0.1j-1.fc21.x86_64
Which hash algorithm does the OpenVPN server certificate use for its signature. If it is MD5, then this is WONTFIX and the server certificate needs to be updated to use SHA256 or at least SHA1. The use of MD5 in certificates is insecure and openssl in Fedora 21 and above and RHEL 7 and above will not support them by default.
Don't know, how to get a certificate from radius UDP port, but our CA for this has md5 signature:
Version: 3 (0x2)
Serial Number: 0 (0x0)
Signature Algorithm: md5WithRSAEncryption
I do not think the CA certificate is a problem here, the signature of the CA certificate is irrelevant. The actual server certificate is.
I made a mistake above with the mention of OpenVPN - it is not in play here, however the same applies to any other TLS server such as the EAP-TLS here.
The temporary workaround is to set the OPENSSL_ENABLE_MD5_VERIFY environment variable in the process that does the certificate verification.
echo "OPENSSL_ENABLE_MD5_VERIFY=1" >> /etc/sysconfig/wpa_supplicant
and then restart networking or computer.
I think you can close this bug as WONTFIX, everyone with this problem can find a solution here.
I'll move it to wpa_supplicant also, so it can be found more easily.
