I did not notice any obvious permission problems when I enabled
ntsec.  Everything I found showed up as mode 777, at least, everything
I looked at in /bin, /lib, /etc (ssh host keys were 700, but we're
not talking about ssh here).

However, I did discover that if I enable ntsec, then I can
successfully login!  

I've made several superstitious changes to /etc/passwd, /etc/group,
but the bottom line is I can now login (telnet and ssh) only with
ntsec set.  If I disable ntsec, I get the usual:

	System Process - Application Error : The application failed to
	initialize properly (0xc0000022).  Click on OK to terminate
	the application.

But only with a domain account.  If I login to a local account, it
succeeds, even without ntsec.

So now I'm running with ntsec.  Chris and Corinna (when back from
vacation), have you tried duplicating this with ntsec disabled,
logging into a domain account?

(BTW, I am quite willing to live with ntsec enabled from now on.)

Thanks,
David
