My test machine is currently an old 8.2 one, but the final machine may be
upgraded. on this machine, if i enter a password longer than 128
characters, extra characters will be exactly trimmed. So, the final
password for any user with a greater-equal input password string, with same
first 128 characters, would be the first 128characters.

has this been changed in Freebsd 8.3+ to what you explained, Eduardo, or
this is the respected behavior? or i am wrong somewhere?

Thank you :)
