Saved password is not updated on successfull login with different password
this happens for me once per 3 months when I'm forced to change my corporate password. After this I just click "Login" on openconnect form (it's remote form, right?) it fails to login because of invalid password. So I have to clear the password field and type it again. Next day I have the same story. The new password is just never saved regardless of "save password" checkbox state.
As a workaround I remove my vpn account and create it again. Then it works. I have a lot of custom settings in this vpn connection, so I have to set them up again and it's somewhat annoying.
