Re: Vpn plugin isn't invoking my save_secrets()

Hi Dan, 
Thanks for the response! The problem seems to work for me now with the latest 
set of patches, thank you very much! One question though, what does it really 
mean for a secret to be agent owned?

save_secrets will only get called if the password is "agent-owned", ie
if the password flags for that password include
NM_SETTING_SECRETS_FLAG_AGENT_OWNED.  The pptp plugin doesn't set up any
of these flags when importing yet, something which I think I have to
fix.  Basically, when importing a connection, or creating a new
connection from scratch, the plugin should probably call:

nm_setting_set_secret_flags (s_vpn, NM_PPTP_KEY_PASSWORD,
