What you are looking for is called NIS:

http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/network-nis.html

However note it is not (unfortunately) interoperable between FreeBSD and 
Linux, although there is a setting (UNSECURE=true in /var/yp/Makefile of 
the NIS server) that works around this, albeit it lowers security.

There are other solutions too (LDAP?) but NIS would be the easiest to setup.
