Thank you, with the --debug flag I've been able to find the problem.

adduser at some point calls "/usr/bin/passwd <newuser>" and it is that
which messes up the NIS line in /etc/passwd.  I have no idea why it is
changing anything in /etc/passwd other than the line for the requested
user.  The useradd and chfn programs, on the other hand, seem blameless.

Demonstration (after already adding a test user "foo"):

maia[28]:~# tail -n 3 /etc/passwd
maia[29]:~# /usr/bin/passwd foo
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
maia[30]:~# tail -n 3 /etc/passwd

Reassigning to passwd (the version in Sarge) as you requested.
