That bit would stay the same. The bit of code that needs to change is
further down:
my $cmpmesg = $db->compare( $userldapentry,
attr=>'userpassword', value => $password );
if ($cmpmesg->code != 6) {
warn "LDAP Auth rejected : invalid password for user
'$userid'. " . description($cmpmesg);
return 0;
}

Would become more like:
my $user_ldapname = $userldapentry->dn();
my $user_db = Net::LDAP->new( [$prefhost] );
$res = $user_db->bind( $user_ldapname, password => $password );
if ( $res->code ) {
$debug and warn "Bind as user failed". description( $res );
return 0;
}
