yp_cat is lacking in PHP5 - this is a suitable (slow, forking) replacement...



<?php

    $handle = popen( 'ypcat passwd.byname', 'r' );

    while (($line = fgets($handle, 1024)) !== FALSE) {

        list($user,$pass,$uid,$gid,$gcos,$home,$shell) = explode (':', $line);

        list($name,$room,$work,$home,$position)  = explode (',', $gcos);



        ## Do Stuff ##



    }   

    pclose( $handle );

?>

I hope this will userfull to somebody:



function auth_by_nis($login,$password,$nis_domain='-d xxx_nis',$nis_host='-h xxx.it')

{

    $output = shell_exec("ypcat $nis_domain $nis_host passwd");

    $lines=split("\n",$output);

    foreach ($lines as $k=>$v)

    {

        list($login_nis,$pw_nis)=split(":",$v);

        if ($login_nis != $login)continue;

        //login trovata: ora si verifica la password

        $salt=substr( $pw_nis , 0 ,2);

        $pass_cript=crypt($password, $salt);

        if($pass_cript == $pw_nis) return 1;

        else return 0;    

    }

    return 0;

}
