PHP: PDO(MySQL) SSL Connection -

i trying establish ssl connection mysql server using following code (on debian gnu/linux 7 (wheezy) php 5.4.4):

$db = new pdo('mysql:host=mysql.myorganization.net;dbname=mydb',      'username', 'password', array(         pdo::mysql_attr_ssl_ca => 'mysqlcertificates/cachain.pem' ));  var_dump($db->query("show status 'ssl_cipher';")->fetchall()); 

but getting error:

sqlstate[hy000] [2026] ssl connection error: asn: bad other signature confirmation 

i can establish ssl connection using mysql command:

mysql -u username -p -h mysql.myorganizataion.net --ssl-ca mysqlcertificates/cachain.pem 

i built php 5.4.4 source , (without running make install) ran

sapi/cli/php ~/projects/test.php 

and following output

array(1) {   [0]=>   array(4) {     ["variable_name"]=>     string(10) "ssl_cipher"     [0]=>     string(10) "ssl_cipher"     ["value"]=>     string(18) "dhe-rsa-aes256-sha"     [1]=>     string(18) "dhe-rsa-aes256-sha"   } } 

i tried looking in php.ini files , my.cnf files see if might upsetting connection not sure looking for.

so question is:

what causing error show when php run /usr/bin/php not when run sapi/cli/php in build folder?

i realize php out of date unable update until our next maintenance window, , feel have done far demonstrates not version issue.

in example not using full path in pdo connection string certificate:

pdo::mysql_attr_ssl_ca => 'mysqlcertificates/cachain.pem'

could try full path below

pdo::mysql_attr_ssl_ca => '/fullpath/to/mysqlcertificates/cachain.pem'
