Re: NM can't save password of VPN connection in system scope

[cee1 <fykcee1 gmail com>]

The connection editor should support this as long as a system settings

plugin is enabled that supports writing out VPN connections.  At the
moment the only plugin that does support this is the 'keyfile' plugin.
Look in /etc/NetworkManager/nm-system-settings.conf to see if it's
enabled.

The keyfile plugin is enabled.

It seems connection editor doesn't support this:

For nm-connect-editor, only the function "save_secrets" (network-manager-pptp-0.7.2/properties/nm-pptp.c) will read user-entered password, and this function is only called for user scope setting.
