Hello,

I think I am missing something with external authentication module and our 2008 AD interaction. It will either give no results or a 500 internal error. I have the ldap module installed in php so I am not sure where I should work.

external authentication .3
server 2008
IIS 7
PHP 5.2

Any help would be greatly appreciated.

Thanks,

Anything in the IIS server log? (sorry don't really know about IIS, only Apache)

A black page usually means an error somewhere.

Nope nothing there. Just gives the unknown error 500 totally confusing. I am thinking there might be something in php causing it. Could you send me a list of php modules that are required for this silverstripe module to work? I guess I'll start there and proceed.

Thanks,

Spencer

You could try the latest version from trunk. It has debug logging features.

If you use AD, the only php module you need is php_ldap. But on Windows I imagine something more is needed (like openldap libs)

Ok finally got PHP to behave hare to use the add and remove programs in windows to enable modules. Stupid.

Anyways I got so far that it is acctually producing a log. So here it is. I am not sure why it would not bind. What should I try next.

Did you use DNS name (FQDN?) or IP? I've run into instances where PHP wouldn't correctly resolve my server name. As soon as I used the IP address the problems went away. Can you actually verify (e.g. using some LDAP tool) that you can bind from the server you are using?

Ok I tried both. I tried 636 with ssl and 389 both as the ports and settings. Another note when I try and enable the user to look up with out anonymous I get a 500 internal server error. I will verify the connect from the server I am on but it is in the same domain so I would assume so.

In this case the server being in the same domain makes no difference at all. PHP reports unable to bind, so the problem is in the php ldap module, or in de ldap (AD) itself. Use http://jxplorer.org to check your directory connectivity.
