Adding remote desktop privileges via dscl

In systems before 10.5, one could add remote desktop privileges for a user with:
<PRE>
% niutil -createprop . /users/<username> naprivs -1073741569
</PRE>

However, in 10.5, running the command above no longer works since NetInfo is gone. So, I tried:
<PRE>
% dscl . -create /Users/<username> naprivs "-1073741569"
</PRE>
adds:
<PRE>
dsAttrTypeNative:naprivs: -1073741569
</PRE>
but does not give the user remote desktop access. Anyone know the proper dscl option for giving a user ARD access via dscl or some other command-line utility?

Thanks,
Charlie
