Description tompermutt 1999-07-16 00:44:49 UTC

With shadowing turned off, setting a zero-length password
seems to corrupt the password data-base.  Whether I do it by
editing /etc/passwd, or using passwd as root, the user is
unable to log on.  Furthermore, even if root runs passwd
again to set a non-null password, that user remains hosed.

I cannot reproduce this.  Are you using NIS or some other form of
authentication besides /etc/passwd?  A non-root user cannot set a
null password with the passwd command; perhaps the old password is
still in force for you?

OK, 3029 does look like the same report...

Comment 3 Michael K. Johnson 1999-08-02 16:16:59 UTC

The bug really does exist.  I'm not sure why I couldn't recreate it
on my machine, but plenty of people have reported it.  In any case,
it is clearly a duplicate of 3029.  Thanks for your patience...
