gdm3 exclude certain usernames

I'm having trouble figuring out how to configure gdm3. I want to
exclude certain usernames from the login screen.

/usr/share/gdm/gdm.schemas has a "greeter/Exclude" section, but is that
really where I should add my usernames to? I was expecting something in
/etc. Maybe it goes in /etc/gdm3/daemon.conf, but I'm not sure of the
syntax.

Any help would be appreciated.

-Rob

Disclaimer - I know nothing of gnome, but no one else has answered...

I suspect you want the front-end (greeter) not the daemon but - see
disclaimer :-)

schema is "possibly" similar to 2.2, see:-
http://live.gnome.org/GDM/2.22/Configuration

Thanks! That website gave me the syntax I needed. All I had to do was
make /etc/gdm3/daemon.conf look like this:

[greeter]
Exclude=myuser

All that talk of schemas had me confused. I think I must speak a
different language than the Gnome developers...

I got a good laugh over that, but believe it or not that mentality does exist
in some people's minds. Back in the mid nineties, I worked for a company that
used IBM's "OfficeVision" as the corporate e-mail system. OfficeVision
ran under VM/CMS on an IBM mainframe. One time, we had what the non-IT-literate
management would call an "outage of VM". (In reality, there was a network
problem that interrupted the TELNET 3270 communications between the 3270
emulation software that ran on user's workstations and the mainframe. VM
didn't really go down. But in management's mind, if they can't logon,
then VM is down.) Anyway, my boss received a directive from
management to send out a notification e-mail to everyone to tell them that
VM is down if VM ever went down again.

How he managed to tactfully and respectfully explain to management that
such a thing was not possible without laughing out loud I'll never know,
but somehow he managed. I'm not sure that I could have done it.

By the way, I know how to cure the absentee problem in our schools.
Instead of the traditional method of taking attendance, the teacher
should say, "If anyone is not here today, please raise your hand."
And if no-one raises his hand, then obviously everyone must be
present. ;-)

That remebembers me... there used to be a GUI app to handle that (in gdm
2.x) that one could launch with "gksu /usr/sbin/gdmsetup" but the same
app under gdm3 lacks for many of its features (in fact, it's pretty
minimal).

Which remembers me - When I was doing a bit of a search last night I
came across comments to the effect that gdm-setup(?) functionality
"will" become part of the new Gnome shell.

...and my claim to know nothing of Gnome is not entirely correct - I am
given to understand that it's some sort of a mouse house that you get if
you install the stock Debian using the Enter key ;-p

Yes, to which I would add that even though Scott's command of the
English language is far superior, or so I am given to understand, as
the only people I know who use such phrases as "I am given to
understand" are scholars or pretentious or both, however the OP can
take solace in the fact that he was able to more clearly communicate
his meaning, despite his apparent disadvantage to the learned scholar
Scott, whose "mouse house" comments remain a mystery to me.

Ugh... that would be an ugly approach ;-(

Can you expand that information?

Accessible/configurable from is what I should have written....

Not really, what I vaguely recall is that system configurations will
become(/be set from) an extension in gnome shell, gdm included. I
assumed that to mean that the daemon.conf would become
configurable/accessible through the shell.

Came across the following in an attempt to track down where I read that.
Don't know if this is relevant:-

Mmm... I'm not planning to move into gnome shell (still) so having to
switch into that just to get more "accessibility" or "higher levels of
configurability" would be a big handicap.

Thanks... that gnome bug (#587750) seems to be key:

***
GDM rewrite needs a configuration GUI panel similar to 2.20 (gdmsetup)
https://bugzilla.gnome.org/show_bug.cgi?id=587750
***

Fortunately, there is no mention for binding "gdmsetup" within gnome
shell :-)
