The root password must be modified in such a way that Netinfo
knows about it. One recipe for this is in the NeXT SysAdmin manual
under the subject "Lost Root Password". The documentation is also
online in /NextLibrary/Documentation/NextAdmin/15_Trouble.rtfd.
The easiest way I know of to change the root password on NeXTstep is
to boot as single-user. then:
# cd /tmp
# nidump passwd . > tempfile
# vi tempfile
# here delete the password field from the
# between the pair of : first line (root) entry
# niload passwd . < tempfile
# halt
Boot again, not as single-user. Root now has a null password.
If you are an awk expert, you could combine the steps and not have the
intermediate file. But it took me a few tries to get it right just now.
So it's easier to use an editor.
