Used to auth people, will check SUCS then the uni ldap, will only check

students on the uni ldap.

will return "sucs" if the username/password passed is a sucs member

will return "uni" if the user/pass passed has a student swan uni account

will return "nope" if the user/pass passed is inavlid

Example usage:

include_once("ldap-auth.php");

isAuthd = ldapAuth("usaername", "password");

if (isAuthd == "sucs"){

	//do stuff for sucs auth

}elseif (isAuthd == "uni"){

	//do stuff for uni auth

}else{

	//do stuff for not authd peeps

}
