I was able to verify that message. It appears exactly as shown above.

That command produces no output. I can run "mkpasswd -d <pc_domain>" and
get a listing of all users in <pc_domain> (which does not include me). I
cannot run "mkpasswd -d <login_domain> -u <myname>" because I get the
above error (after it displays the "well known" accounts).

That is certianly possible.

I have created my /etc/passwd and /etc/group files by hand and they work
fine for ntsec and telnet and ftp. It is only cron that has a problem
and only cron that attempts to switch user context to my domain account
WITHOUT a password. This is what led me to believe that this is
actually intentional behavior. It seems to me that without this
behavior, one could easily impersonate another domain user simply by
concocting the proper /etc/passwd entry and creating a crontab job for
that user.
One other slightly odd thing is that my RID (i.e. the last number of my
SID) is greater than 65535. So in the uid field of /etc/passwd, I have
to put (RID modulo 65536) otherwise things don't work right. For
example, if I put the larger number (i.e. actual RID) in /etc/passwd as
my uid, doing an 'ls -l' on files I own (as shown by Win2K) doesn't show
my /etc/passwd user name in the owner column, but instead shows that the
owner's uid is the (RID modulo 65536) value.
Thanks for you thoughts,
Dave
