You can copy these files:

/etc/group
/etc/login.conf
/etc/master.passwd
/etc/passwd

And DB files

/etc/login.conf.db
/etc/pwd.db
/etc/spwd.db

Or you can recreate them with pwd_mkdb and cap_mkdb (see their man pages)

If you installed some shells like bash or zsh for users, then you must 
installed them too and verify /etc/shells settings.

Additionally you may need a copy of /etc/profile and /etc/csh.cshrc if 
you modified them.
