Networkmanager not able to remember LAN password (802.1X)

Post by Tomas_IV »

Hello,
it is about a month back when my wired 802.1X network connection stopped to work (working for several years without any issue up to that time). It tried to connect, asked for password, and when supplied, asked it again after a while, and again, and again...
I tried everything, including removing and recreating the connection definition, with and without certificates (updated these). It was at work so then went to our IT dept. and they tried basically the same and found, that the connection works without issues, if you check the option to ask the password every time. After the month I am a little tired of supplying the password after every reboot, so I tried and it is still the same, means if I check the option to ask password every time, I am asked for the password and connected. If I uncheck it I am also asked the password (regardless if i store it in the connection settings or not), but not connected and asked the password again. Has anyone similar experience?
Tomas

Output of few commands (while connected, after trying unsuccessfully the connection with remembering the password once, then reverting back to ask it every time):

Tomas_IV: I suggest you could try this to see if it helps...

Right-click on the NM applet and then select "Edit Connections" from the menu.
Select Ethernet > Wired connection 1.
Click on the "Edit" button and then select the General tab.
Select the following two checkboxes:
"Automatically connect to this network when it is available"
"All users may connect to this network"
Hit the "Save" button then close the NM editing screen.

Reboot and Login again and see if the password is still being requested.

If the above works correctly then you may be able to deselect the "Use 802.1X security for this connection" checkbox in the "802.1x Security" tab. This is because wired (ethernet) connections often work by default without any security settings.

Thanks for the suggestion, but I have the settings exactly as you recommend already. And no, LAN connection without 802.1X authentication is not possible in our network.

The following three Ubuntu bugs may be relevant to this problem: Bug #1173152 seems to have a couple of workarounds in Comments #12 and #19 that may be helpful.
