Me too. Yesterday I upgraded from 12.10 to 13.04, and my Ethernet connection with 802.1x fails to connect. It always asks for the user and password, even the user and password is setted in the configuration.

Thanks for all.

Status changed to 'Confirmed' because the bug affects multiple users.

Can we help in any way to debug this?

Yes, you can help. I don't know what to do get some debugging info.

Yes, If I can help to provide debugging info, I will be pleased to do it.

For me is very important this bug. The corporative network in our company needs 802.1x ethernet to work, so I have no network at work with my new Ubuntu.

yesterday I had recently upgraded 12.10 to 13.04 32 bit and I had it working. Although I decided to move to a fresh 64bit install of 13.04.

After the fresh install of 13.04 64 bit and I am suffering the same problem and network manager indicator ends up crashing when it tries to connect.

Only possible workaround. Configure wpa_supplicant manually.

For those who need:

/etc/wpa_supplicant.conf

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=2
ap_scan=0

network={
       key_mgmt=IEEE8021X
       eap=PEAP
       phase2="auth=MSCHAPV2"
       identity="YOURUSER"
       password="YOURPASSWORD"
}

###########

/etc/network/interfaces

# LO
auto lo
iface lo inet loopback

# ETH0
auto eth0
iface eth0 inet dhcp
wpa-driver wired
wpa-conf /etc/wpa_supplicant.conf

##############

I can't get working this workaround, but I'm not very familiar with this kind of configuration, and it may be my fault.

I am experiencing the same issue after installing 13.04, and also could not get the workaround working. I continually get prompted for the password, and can confirm this was working in 12.10. Unsure what debug logging would be useful, but here is the error in my syslog:

I've got this problem too and the workaround didn't work for me

It turns out removing the line "system-ca-certs=true" from the /etc/NetworkManager/system-connections/<network id> file seems to have allowed me to connect to the network. The nm-applet stills asks me for my password a few times, I don't know if it is related, but at least it does eventually connect.

Sebastien, great!!! This workaround works for me.

Thanks a lot Sébatien!!!

This workaround also worked for me. Now I can use wired network at work.

One more thing, I also have the same problem for Wifi connections. And the same workaround solved the issue.

Excellent! Sébatien!!
This workaround also worked in my environment(ethernet and wifi).
I hope that this bug is revised as soon as possible.

Workarround worked for me too:

on WIFI with TTLS/PAP

thanks!

Workaround work very well!! Thanks a lot!!!

This is a really embarassing bug especially for us enterprise users.

Sébatien's workaround works but you're then required to enter your password each time you connect to the network.

Adding this line to etc/NetworkManager/system-connections/<network id> fixed that for me:
password=<password>

So the workaround is to remove this line:
system-ca-certs=true
and add this line in its place:
password=<password>

Though storing your password in plain text like that is not great :(

I should also point out that I needed to restart for the changes to take effect.

Thank's Sébastien! It worked also here!
