Usually this is done via the PAM libs on most modern Unix type systems. This
provides an abstraction layer between the application (login, ssh, xdm etc)
and the authentication system (ldap, shadow passwords, kerberos etc).
Most distributions install the documentation for PAM but in case you haven't
actually got a linux box yet, try http://www.kernel.org/pub/linux/libs/pam/
(first entry when you type PAM and linux into google).
