Comment 12 for bug 844044

I've added a "greeter-show-manual-login" option to lightdm 1.1.7 so a system administrator can indicate to the the greeter that it should always show a manual username option. In the branch lp:~robert-ancell/unity-greeter/bug-844044 I've proposed support for this in Unity Greeter which would have the default install show as in the screenshot below.

However, this does not solve this request of this bug. The request is to add a specific "Network" option. There are two issues with this currently:
a) We cannot tell what the system administrator has configured PAM to do, thus we cannot detect if this machine can or cannot access network accounts.
b) We cannot restrict this "Network" entry to only network accounts (*). So the naming is confusing.

(*) techincally not true as we could make a special PAM service that only allowed network logins, however I don't think this is really what this bug is requesting.
