Just a quick update on an email Casper Dik just sent. I think this 
needs to be in the archive.

Thanks a million Casper.

Kind Regards,

Checking the npasswd documentation one finds:

passwd.MaxPassword

       Usage 		Type 	Default value
     passwd.MaxPassword 	number 	8*

	Sets the maximum effective length for passwords. This reflects
	a limitation of the standard crypt(3), which encrypts only the
	initial 8 characters of the plaintext. On Ultrix and Digital
	UNIX (aka OSF/1) with enhanced security, this limit is 16.

	It is not an error for a password to be longer than the
	maximum, but the password checker can be configured to issue a
	warning. See passwd.LengthWarn.


Which clearly indicates that npasswd does not support passwords
over 8 characters (certainly, the length of password which is supported
by npasswd is irrelevant as it is the OS crypt() routine which
decides what works.
