Comment 21 for bug 188349

Ubuntu hardy heron 8.04 amd64 / x86_64
(from alpha 5 up to beta through updates)

I still get this bug,
network-admin > press unlock, type in your password > select your connection (mine is wired, eth0) > properties > (change something) > press ok

Results in an error:
The configuration could not be saved.
You are not allowed to modify the system configuration.

However, although the error pops up, the information for wired mode mentioned in the main "network settings" window seem changed when I altered it in the properties. But the nm-applet resets and gets the old configuration, so I think it doesn't save the changes.
