If you are talking about your particular installation, then sure.
But your statement above "when using NT" is then mis-leading.
We have tons of customers NOT using the NT SAM and "using NT".
Our solution is more scaleable, more robust, and more secure (and
much less troublsome). Also, we are not talking about Running
NT w/out SAM itself, just all the applications and users (like
Mail, FTP, RADIUS, etc).

In your implementation, you are creating a security issue when
you add users to the NT SAM. With Emerald, everything authenticates
from a SQL Server database, therefore the users are NOT in the
NT SAM. Your applications (like FTP, Mail etc) run as a minimal
access user. They use information out of SQL Server to allow
access to files, etc. It doesn't require changing permissions
every time you add a user. It just always makes me cringe when
someone says they are using the NT SAM for this stuff. :(
