Fedora 11 GDM - unwanted list of all local users and impossible to customize?

[jaivuk]

Hello guys,

I did not use gdm for some time and now I'm not happy how it looks in Fedora
11.
First of all - the list of local users is unacceptable from security
reasons. Even if it supports such "an " option - how it can be the default
one?!
Second problem I have is shutdown button (and possibly restart as well) -
when you click on shutdown button by mistake, system will shut - there is no
confirmation dialog.

I also tried to find some ways how to customize gdm in Fedora 11 but I did
not find any usable guide.

Can anybody please advise me how can I have prompt asking for username only
(showing last logged user at maximum) and not displaying the list of all
local users?
Also can I somehow add confirmation or remove shutdown restart buttons from
gdm screen?

Or can you please advise any alternative to gdm?

Thank you very much,

Jan
