su password, again

[Stephen Tenbrink]

I received a lot of responses to my original questions concerning the root
password location on the NeXt computer and would like to thank those who
responded.  Let met restate the problem/issue:

  I must type a password when I type 'su' and when I login as 'root'.  The
problem is that the passwd file has no encrypted password entry for 'root'. 
It does have encrypted passwords for all the users.  What I want to know is:
where is the encrypted password kept for root?

The other problem I think has already been answered.  I can login as 'root'
from the console but when I try to telnet from another workstation and login
as root I can't do it.  Someone suggested that there is a security feature
that only allows logins for root to occur at certain terminals (in this case
the console).  That makes sense.  Now if someone can tell me what happened
to the encrypted root password in the 'passwd' file my curiosity will be
satisfied.
