Problem with LDAP Extension in IIS and PHP

GHS-Helpdesk

Alright, I've been trying this for several weeks now, and it's starting to get frustrating. I am a helpdesk administrator for the local High school.

We are running IIS 6 and a PHP Build of 4.3.10. I've had no problems enabling and compliling with the GD libraries, but when I try the same procedure using the LDAP dll, I get an error message saying 'Access Denied'. Both dlls have the same permissions and are both in the same folder.

I have moved all the dlls in the dll folder to the System32 folder. No help. I guess the problem is some sort of athentication error, but I can't seem to track down the source of the problem.

Any help or insights would be greatly appreciated.

Hi,

make sure that php.ini is in the c:\windows directory and that the IUSR_???? user has at least read and read-execute access on all dlls PHP needs in system32 (copy all the neccessary dlls to system32).

If that doesn't help then add the IUSR_???? (recursively) to the PHP root directory, too. Also make sure that all dlls the ldap extension dll depends on are in system32 (or at least in a directory that is in the PATH environment variable).

Do you have IIS authentication enabled ?

In an exacerbated attempt to get it working, the directory that I have the extension dlls in, was given full access by everyone.

IIS Authentication shouldn't matter, because PHP is compiled outside of the server environment. And like I said, I had already compiled the GD Libraries into my build of PHP.

It's quite possible that I'm simply just missing a step. If the ldap libraries included with php (php_ldap.dll) and the dlls in the 'dll' folder. (Places in my System32 folder). I uncommented the extension line and added the --with-ldap switch to my .ini file.

The biggest kick in the pants is that, just for fun, I loaded all the extensions in the directory. About half of them got the 'Access Denied' error, while the other half compiled succesfully. And bear in mind that they all have the same permissions on the files.

Any Ideas?

Alright, I finally found the solution to the problem, so if anyone else has this error message with most extensions, it's an easy fix. So easy it's almost beyond comprehension.

The error is caused by a lack of dlls in the php root directory.

Common Cause: Windows PHP Installer.

Easiest fix: Install PHP using Installer. Download ZIP Package. Extract over PHP installation.

Should work fine.
