I'm using php 5.2 with IIS7.5.
I have a network share on a NAS that is username and password protected. I cannot disable or change authentication info on the NAS. I need to be able to access that network share via php.
I've done the following:
Created new user in windows whose username and password matches those on the NAS. Created IIS application pool that uses this same auth info. Created a web.config file inside of the php app directory with an impersonation turned on, using the same auth info.
identity impersonate="true" password="ThePass" userName="TheUser" />
Turned on ASP.NET impersonation in the application authentication in IIS.
None of this seemed to work with this simple line of code in php:
$dir = opendir("\\someservername\somesharename"); Warning: opendir(\someservername\somesharename) [function.opendir]: failed to open dir: No error in C:\websites\site\forum\testing.php on line 7
So, I decided to test the configuration with ASP.NET.
string[] diretories = System.IO.Directory.GetDirectories("\\someservername\somesharename"); The asp.net test worked perfectly.
Going further down the rabbit hole, I ran phpinfo() and checked the username info in it. Down in the "Environment" section of phpinfo, I found the "USERNAME" item. Its value was "TheUser," as was what I expected.
Everything points to the system being configured correctly until I tried:
echo get_current_user(); Which returned, "IUSR." That surely isn't what I expected.
So, how in the world do I get php + IIS7.5 to read from a foreign network share?
Update:
Thanks to a few of the answers, I've added
$result = shell_exec("net use o: \\\\pathToServer\\27301 /persistent:yes 2>&1");
Which returns a success. I'm still getting the error on opendir. I tried another test and used is_dir. This returned false on my newly created mapped drive.
var_dump(is_dir("o:\\"));
// Prints: bool(false)
UPDATE
I ran the script from the command line when logged in as the user that created. The scripts executes correctly. Could this take us back to get_current_user() which returns IUSR? I tryied getmypid() which returned a process ID. I cross referred that process id with the task manager and found that it was for php-cgi.exe, running under the custom user account that I made.
