Description mw 1999-07-16 18:06:31 UTC
When the password field is empty in /etc/passwd, passwd does
not add the encrypted passwd to the field, and it does not
indicate it with an error.

Here is the complete experiment:

# useradd okidoki
# grep okidoki /etc/passwd
# emacs /etc/passwd         (empty password field)
# grep okidoki /etc/passwd
# passwd okidoki
Changing password for user okidoki
New UNIX password:                     (typed MaciLaci)
Retype new UNIX password:              (MaciLaci)
passwd: all authentication tokens updated successfully
root@moni: ~
# grep okidoki /etc/passwd

How can this be a problem (besides, that I think it is not a
correct behavior) since RH 6.0 does not let you log in w/o
an empty passwd field?

Well, imagine that on a yp server, after emptying the passwd
field, I run passwd (thinking passwd is set), then run

(cd /var/yp; make)

Now, on another older (5.2) RH box on the same NIS domain, I
could log in as okidoki w/o a passwd!  (I ran this
experiment with a 5.2 box as a yp server but passwd-0.58-1
and pwdb-0.58-3 installed).

Let me remark that yppasswd seems to behave correctly, but
linuxconf also gets confused (I guess it is running passwd).

This has been confirmed in the test lab.

Should be fixed in the next release.
