Description:
------------
With the latest 5.2 (and trunk), you can't have multiple fields with the same name in the DN.
E.g. it's impossible to produce CN=server, OU= Company, OU=Division, OU=Sector, O=Organization
Reproduce code:
---------------
$dn = array("commonName" => "server",
"organizationalUnitName" => array("Company", "Division", "Section"),
"organizationName" => "Organization",
);
$privkey = openssl_pkey_new();
$csr = openssl_csr_new($dn, $privkey);
openssl_csr_export($csr, $csrout);
file_put_contents("test.csr", $csrout);
Expected result:
----------------
openssl req -in test.csr -noout -subject
subject=/CN=server/OU=Company/OU=Division/OU=Section/O=Organization
Actual result:
--------------
PHP Notice: Array to string conversion in /var/www/html/bug/cert.php on line 9
Then:
openssl req -in test.csr -noout -subject
subject=/CN=server/OU=Array/O=Organization
