Actually, su would have to read /etc/master.passwd since that's where the
actual passwords are located.

Since /etc/master.passwd is only readable by root, this might be the
problem.  It looks to me like you didn't install your binaries correctly.
I could be wrong, but on NetBSD systems, most binaries are owned by user
bin and group bin, so yours is probably wrong.  Ah, here is the copy of
'su' from the NetBSD CVS server:

24 -r-sr-xr-x  1 root  bin  12288 Jan 30 00:01 /usr/bin/su

Note that it is owned by root:bin and that it is setuid root.  That
explains your problem.  If you installed from within NetBSD (which it
appears that you did, the Installer should give the correct permissions),
you need to reinstall with the -p option to tar. This will "preserve"
permissions on the files as you unarchive them.

I hope this helps.

Later.
