Hi Steve, No, adding ypServ30.ldif is a bit like adding the 
automount.ldif, you need the right objectClasses & attributes in the 
schema first. If you are interested, you will find ypServ30.ldif in 
/usr/local/samba/share/setup/, but from my investigations, it does not 
seem to be the full ldif that windows added.
It would seem that to get the UNIX attributes tab to show in ADUC, you 
need to be running Windows server 2003R2 (aka Samba4) and have 
ypServ30.ldif installed (aka SFU 3.5 or whatever they are calling it 
this week)
