All it does in that case is run "passwd" with no arguments.  If you log
on (via telnet or ssh) and just run "passwd", does that work?

Solaris doesn't seem to support usernames longer than 8 chars:
$ uname -sr
SunOS 5.8
$ sudo useradd abcdefghi
UX: useradd: abcdefghi name too long.

You can try building with and enabling PAM (that's probably what telnet
is using).

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
