Thank you for this. I didn't realize I had installed php without the ldap feature. PHP info always showed that I had LDAP when I checked it. I reinstalled PHP and setup fastcgi again.

I have the same behavior as you, "You have entered an invalid username or password". I had been receiving an error that the initial bind failed, but now I don't even receive this error.

Attached are the cumulative changes/updates for product-ldap_auth-1.5.xml provided by cowbert and john.parlane for running in version 4 so you don't have to update it by hand yourself. Thanks to all who have made this possible!

Also, make sure you install the php-ldap package via yum if you are running Linux, and then restart your apache server after you've installed it.
e.g.
> yum install php-ldap
> restart apache

Cheers,
Jim

changed vbull.user to forum.user in the user database query lookup so it will properly look up existing users

Thank you so much! I finally got this working, but now I'm not sure if it was from your code change or how I set it up this time. I was still getting the LDAP bind errors when I tried the changed code. After trying more settings I finally got it working by pointing the base DN at an OU first. OU=ou name,DC=domain,DC=domain,DC=org. Not sure if I had tried that in the past or not because I tried so many, many combinations. Unfortunately, it will ONLY work by pointing to an OU. If I try the root of the domain it won't bind. DC=domain,DC=forest domain,DC=org. I was hoping to point to the root of my domain or even the root of the forest because I may end up having to allow logins from other domains. The way it is right now I have to exclude the IT department from ldap logins so that I can point to our users OU. If you have any ideas on how I can get it working by pointing to the root I will be very grateful. Regardless, thank you for putting this up. I can't tell you how many hours I've put into trying this mod and a few others for ldap authentication.

Big thanks,
Gina

I'm having issues getting this working with our setup.

vBulletin 3.8.2
Openldap (linux debian)
php 5
product-ldap_auth-1.5.xml

It is binding ok, but setting Naming Attribute to what we use in the OU - "uid" it isn't picking up the username.

Full Name Support for LDAP Auth - seems to work, using the same username on vbulletin database as it is in the ldap database.

Just can't login with users using ldap auth details, also the mod isnt disabling vbulletin users.

With this version do we need to do the edit to config.php or global.php to add

Also: do any other edits need to be made?

How can I make any errors with this output to a log? I would like to better diagnose my failures.

There is a lot of good information scattered around this thread for connecting this plugin to Active Directory. In the interest of making things a bit more clear, here are the additional steps required for connecting to Active Directory:

Active Directory:
You need a user to query Active Directory

Firewall:
Don't forget to open firewall ports for authentication if you are working with a DMZ or the like.

LDAP Authentication Settings in vBulletin:
Anonymous Bind: No
Bind DN: <Domain>\<Username>
Naming Attribute: sAMAccountName
Search Base DN: OU=<Whatever>,DC=<your_domain>,DC=<your_domain_tld >
LDAP Attributes: fullName, mail, sAMAccountName

Some points to keep in mind:
1. This plugin doesn't seem to work if your Search Base DN begins with a DN in AD. You must have your search base begin with an OU. This means that if you have multiple OU's at the top level of AD that contain users, you may have a problem.
2. The Bind DN should be passed in the format shown above.
3. Make sure to download product-ldap_auth-1.5_vb4.xml found in this thread, not the one from Haqa's original post. This version contains patches needed for vBulletin 4.
4. The product-ldap_auth-1.5_vb4.xml code attached to this post has a change so that you do not have to specify your DB name:

5. WARNING: If you aren't running vBulletin over SSL, you will be passing your Active Directory usernames and passwords in clear text.

Anything else?

Thanks,

Kirk.

Awesome plugin, one request though, how can I set it to give the LDAP users specific usergroup(s) by default?

Okay so I needed to use this for a setup that we have using Active Directory. Kirk's (KPatten) version was great, but being a hacker at heart I tweaked it. I thought I'd share this with the community as a way to say thanks. All the caveats and instructions that Kirk gave in post 127 still apply.

Differences:

• Option to update the username of existing vbulletin users. I believe this is how it was supposed to work, but it didn't for me
• New database field on user table to store which users are LDAP users, and provides an option to prevent access when those users are removed from AD
• Lots of debug messages (I found this VERY helpful), with an option to disable. (requires includes\devtools.php I got this from here)
• Puts LDAP 'displayname' into user field5 (I've found this to be a pretty common place to put a user's display name, although arguably I should have used the extension points as originally intended)
• Puts LDAP 'title' into user field4 (This is "occupation" in my install)
• I set the minimum version to 4.1.5 - this is because I haven't tested it on anything older, but there's every chance that it will work on whichever system Kirk's works on. Please let me know if this is the case, and I'll update the files here.
• Puts an entry into the user table to indicate if they're an ldap user or not - this requires a new column to be created in the user table: 'ldap'. This is done by the install code for the product. This allows the system to disable users who have since been disabled by ldap, while still allowing external users to use the system.

For this to work you'll need the following files. They go in the following locations:
./includes/xml/hooks_ldap_auth.xml
./includes/devtools.php

A big thanks to everyone who has contributed to this solution: kpatten, haqa, malcolmx and zemic.

I followed this process and am getting...

I am assuming this means I do not have ldap enabled for PHP... any thoughts on an easy way to "add" LDAP to an existing install? What specifically needs to be included and where?
