To properly diagnose the problem, we need a backtrace to see what is happening behind the scenes. To find out how to generate a backtrace, please read http://bugs.php.net/bugs-generating-backtrace.php for *NIX and http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32 Once you have generated a backtrace, please submit it to this bug report and change the status back to "Open". Thank you for helping us make PHP better. ------------------------------------------------------------------------ [2013-02-21 17:38:48] andrew+bugsphp at wimpyprogrammer dot com Description: ------------ (I am using PHP 5.4.12 NTS, but it's not an option in the version menu. I tried grabbing a Windows snapshot but the 5.4 links on http://windows.php.net/snapshots/ are broken.) Calling ldap_bind() with an ldaps:// resource causes PHP via FastCGI to crash: HTTP Error 500.0 - Internal Server Error C:\PROGRA~2\PHP\PHP_5_4_12_NTS_x86\php-cgi.exe - The FastCGI process exited unexpectedly If the resource is ldap://, the connection succeeds. If I change my PHP version to 5.4.11 with the same PHP INI, both methods succeed. Test script: --------------- <?php // From http://php.net/manual/en/function.ldap-bind.php#example-4224. $ldaprdn = 'uname'; $ldappass = 'password'; // connect to ldap server $ldapconn = ldap_connect("ldaps://ldap.example.com") or die("Could not connect to LDAP server."); if ($ldapconn) { $ldapbind = ldap_bind($ldapconn, $ldaprdn, $ldappass); if ($ldapbind) { echo "LDAP bind successful..."; } else { echo "LDAP bind failed..."; } } Expected result: ---------------- LDAP bind successful... Actual result: -------------- Error Summary HTTP Error 500.0 - Internal Server Error C:\PROGRA~2\PHP\PHP_5_4_12_NTS_x86\php-cgi.exe - The FastCGI process exited unexpectedly Detailed Error Information Module FastCgiModule Notification ExecuteRequestHandler Handler PHP 5.4.12 NTS x86 via FastCGI Error Code 0x000000ff Requested URL [Redacted] Physical Path [Redacted] Logon Method Anonymous Logon User Anonymous ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=64267&edit=1
