Lion Server, SL Client - list of users not displaying - only 'other'

Question

#1
So I've been running a SL Server at home without (many!) problems. All SL clients connected to server just fine and you always got a list of users to log in from (as you'd expect).
However, installed Lion Server from scratch on a my Mini Server (again without too much problems). All my client Macs (Macbook Air, Macbook, iMac - all core2duo etc) have been upgraded to Lion as well and they're all fine. You get a list of possible users to log on to - which is fine.
However, I have one core duo (white) 2.0Ghz iMac which (obviously) is remaining with Snow Leopard client but does not display a list of users -- just Admin and 'Other. I've triped check the settings and bearing mind this was ok with SL Server, I can't figure out why this is. I even re-installed SL client on said iMac and I still get no list of users.
I can log into the server using 'Other' i.e. specifiy full user name and password, so I know it is connecting to the lion server
So I am confused as to whether its a Client or Server problem (I presume server) -- any ideas?

Less of a serious problem, I am still getting the old (SL server) welcome message on all my Lion Clients logon screen (i.e. on the list of users) - how can this be if the 'welcome to snow leopard server' has been completely erased with Lion server? (I assumed the message was stored in pram but again, zapping it, does not change it)  I can't find in Lion server to config the welcome message either. Maybe zapping Pram of server? any ideas?
Thanks in advance

Hi
Managed Preferences are composited (combined) together and cached locally on client workstations. These are stored in /Library/Managed Preferences. Remove the folder and restart the workstation. Hopefully on next client login this should pick up what you've defined for MCX at User, Computer and Group level.
For your other problem on the 10.6 workstation issue these commands:
sudo rm -R -v /Library/Preferences/SystemConfiguration
sudo rm -R -v /Library/Preferences/DirectoryService
sudo rm -R -v /Library/Preferences/edu.mit.Kerberos
sudo rm -R -v /Library/Managed\ Preferences
sudo rm -R -v /Library/Caches/*
sudo rm -R -v /private/tmp/*
sudo reboot now
On successful reboot login as the local administrator and assign the workstation an appropriate name in the Sharing Preferences Pane. Make sure it's using the same NTP Server as your Server and then join it to the LDAP Server using the Accounts Preferences Pane > Login Options > Join. Hopefully this should get things back on track.
HTH?
