hardy updates and low fat clients

Is it possible to do the local apps setup/low fat clients without ldap?
Since we are already authenticating against an AD, would we have to
setup ldap to work with that?

	So I upgraded our school server to Hardy and battled with some
issues which surfaced and I'd like to document here for anyone that runs
into similar problems:
	1. Firefox 3 beta 5 froze thin clients across the network,
freezing not just the application itself, but other applications too.
Reverting to firefox 2 has fixed this completely, and it is certainly a
strange issue as I seem to be the only one that saw this issue. That
said, after looking over the ubuntu forums, there are many users that
seem to have reverted to firefox 2 until 3 is not beta anymore.
	2. Removable media shows up on everyone's desktops... this was
fallout from the move from gnome-vfs to gvfs, a good move, but bringing
up its own set of problems. This is a known bug and being worked on, and
there should be a fix coming very soon.
	3. using the workstation plugin (low fat clients) seems to work
wonderfully under hardy (though need to take out the powerdev user
group, and install flash, ldap, nfs in the chroot.) Anyway, the plugin
has simplified the process to create low fat clients considerably...
take a look here:
	Other than that, installing Ubuntu Hardy with LTSP support was
as easy as following this guide:
	I moved from using 64 bit Ubuntu to using a 32 bit kernel with
support for lots of ram, and this has fixed a plethora of issues for me.
My advice for anyone running 64 bit is to move to 32 bit unless you're
running a highly used web server or something... otherwise, the 64 bit
extensions are not noticeable...
	Kind Regards,
