pfSense

I'm still seeing this on the Jan 18 Snapshot. Only reason I can assume that you're not seeing it is possibly because this config was upgraded from a 1.2.3. So try changing username and pw in 1.2.3 from admin/pfsense, upgrade to 2.0 and then try changing the password in 2.0 with that username.

Yes confirmed, just formatted disk and freshly installed 1.2.3. Upgrade to 2.0, the unable to find uid for XXX error flashes during the initial boot process after the firmware upgrade, right before the rrd graphs are updated.

There is still a password sync issue as of pfSense-2.0-BETA1-20100324-1017. When upgrading from 1.2.3. to this snapshot the SSH password is reset back to its default "pfsense". The WebUI password remains the same as it was under 1.2.3. Setting the password via the WebUI after the upgrade syncs the SSH password with the WebUI password again.

This is probably related to an issue I've seen that the root/admin password on the console is not updated after I do an upgrade + config restore (nanobsd platform; I upgrade from 1.2.3, reset to defaults, then restore my 2.0 config). I think it may have to do with these lines in /etc/rc.bootup:

echo "Synchronizing user settings...";
if (!isset($config['system']['webgui']['backend']))
    local_sync_accounts();
echo "done.\n";

That setting looks like this in my config (with other stuff removed):

<system>
    <webgui>
        <backend/>
    </webgui>
</system>

Meaning that it is set. Should it maybe be using empty() instead of !isset()? I don't know a lot about that setting or the internals of the user manager, so I'm not really sure.

Looking through the history, this "backend" setting seems to be something that was removed, so this check in /etc/rc.bootup probably needs to be changed to something else entirely.
