Who told you that? We'd like a word with them. :-)
When you say "longer" I'm also assuming that you're referring to MD5
style password strings (tip-off: they all start with "$1") vs the more
traditional DES passwords. Neither requires any form of special kernel
support and what you need on a DES system is simply the des distribution
loaded. If you did not already load this at installation time, it's
also no problem at all - simply grab the des distribution for your
release from ftp.freebsd.org if you're in the U.S/Canada or
ftp.internat.freebsd.org if you're outside. Run the des distribution's
`install.sh' script ("sh install.sh" works well) and you're in business.
The longer MD5 passwords are always supported by default and, assuming a
reasonably recent FreeBSD version (2.1.7 or 2.2.x), you can use both in
the same password file if you have the DES bits loaded - the system is
smart enough to tell the two types apart when decrypting them.
