Username and LDAP (Alternative Username)

Post by kevinp63 » Wed Jan 30, 2008 11:55 pm

Recently installed 3.0 and connected it to the company LDAP server all is great!

In our company, LDAP credentials are Employee Number/password. Anyone in the company can login but it uses their Employee Number for their board username. Not very user friendly... Is there a way to alter this to display FirstName LastName instead? I can (probably)figure out the getting the FName & LName into the database on login, but how would I then display those 2 instead of Employee Number for all instances of username??

Thanks in advance for any suggestions...

I just got this working tonight on phpBB 3. You can change the username that it looks for by changing the LDAP UID field in the LDAP settings. If you're using Active Directory just use Active Directory Explorer to find all the available fields. For example my setting is simply 'cn' (don't put those quotes in the textbox). I haven't figured out how to merge them like you want. I'm looking to do the same thing. I hope that helps.

**********UPDATE**********
In Active Directory I just set mine to use the displayName field.

Thanks, good to know I am not the only one looking for this...

Question - Do your users still log in with their Emp#? Or their DisplayName?
We have several Tom Smiths etc...

I am hoping to leave the login as is but just like it retrieves email from LDAP at every login, I want to also grab DisplayName and update the DB... Would need to add a DisplayName field in the DB

Then once logged in, replace all instances of UserName with DisplayName.

Not sure where to begin.

I took a look at the '_users' table and there are two user name columns in it. 'username' and 'username_clean'. The first one looks like a case sensitive version (perhaps just to act as the display name) and the other is all lower case. In my table it's the same as the 'username' column but all lowercase. I don't know if you could modify the php code to fill those two columns with different LDAP query results. Maybe I'll create a dummy user and manually edit the table to see what happens. Obviously modifying the code will be required but this might provide some insight into how it's working without digging in to the code.


******UPDATE******
I manually went into my database and updated my 'username' column (after backing up of course). I was only able to login with my login name that LDAP was set to use and when I made a new post it logged my username as 'test' (which is what I changed that entry to). I was not able to login with 'test' as my login name. I also tried logging in with a mix of caps in my LDAP login name and it looks like the login is case insensitive. So it looks like all you'd have to do is find in the php code where it writes in the username_clean field and add some code after it to modify the 'username' column to whatever you want their username to look like. Or if you want it to query LDAP at every login you'd want to add it after the email address check.

Do you know what page I should edit for this?

You'll probably want to look at the 'user_add' function in the functions_user.php file. I'm not 100% sure on this so you might want to mess around on a test BB. I'm fairly new to both php and phpBB so I can't offer any promises. From what I'm seeing on my side of things the LDAP email address is only getting pulled at registration time. You'll probably want to look at the 'login' function in 'auth.php' or the 'login_ldap' function in the 'auth_ldap.php' file. The 'login' function calls the 'login_ldap' function.

Hey,

Thought it was about time I registered.

I've two test boards setup, one using the CN and the other FULLNAME (Novell LDAP), my only concern about using the FULLNAME is how does it handle duplicate names in the system - does it just fail or try and match the password to all users with that name and then authenticate if the correct user is found?

I've been trying ta do the same as kevinp63 - i.e. using the 'Employee Number' as the login name but showing their full name are the PHPBB username but still no joy.

I have REALNAME as my Custom profile field where I store the persons name.

So far I have edited viewtopic_body.html and replaced username with this:

Code: Select all

<b><a href={postrow.U_PROFILE}><span style="color: {postrow.POST_AUTHOR_COLOUR}">{postrow.PROFILE_REALNAME_VALUE}</span></a></b>
And on memberlist_body.html I replaced username with this:

Code: Select all

<b><a href={memberrow.U_VIEW_PROFILE}>{memberrow.PROFILE_REALNAME_VALUE}</a></b>
This page doesn't really let you search by letter though...

Anyway, I am stuck at the Index page trying to make Moderator, Last post author, and Registered Users use my custom profile field.

If that can be figured out I am sure it could carry over to viewforum...

I had the same problem so I added a custom field fullname in profile. I edited the auth_ldap.php such that each time the user login, his name is read from LDAP and inserted into phpbb_profile_fields_data. But I have one problem...The custom field can be edited by user. I cannot make the field hidden. If user edits his name, it will remain as it is until the user login again. Is there anyway to prevent the user from editing the custom field?

EDIT: I edited the file ucp_profile_profile_info.html and commented the custom profile field part. But this can't be a solution in case I need some of the custom fields to be edited by user.

I'm trying to get this to work too...without much success.

The problem is that I don't know how phpBB pulls data out of LDAP - what is stored in $ldap_result?

Does auth_ldap.login_ldap.$ldap_user_row (as Array) have anything to do with $user_row in function_user.user_add() ?

I'm trying to achieve something like this - populate _users.username with 'Firstname Lastname (empCode)' and _users.username_clean with 'empCode'. I've tested changing the username to this format directly through the MySQL console, whilst leaving username_clean as is. Login using LDAP with the old username_clean + password works fine and posts display the new (more descriptive) username, which is exactly the behaviour I want.

Can anyone shed some light?

(forgive me but I'm very new to PHP code hacking - have come across from the dark side that is Java).

I've got this working by using an unused profile field in my environment - Being "Location"

This enables users to sign on with the true "samaccountname", but return the more descriptive "displayname" field shown when viewing posts and so on..

I've included to the required code mods here;

Some enhancements if I may...




First in regards to the last comment, this will resolve the error.

File:- /includes/auth/auth_ldap.php ~ line 161
Original

Code: Select all

    $search = @ldap_search(
                    $ldap,
                    $config['ldap_base_dn'],
                    ldap_user_filter($username),
                    (empty($config['ldap_email'])) ? array($config['ldap_uid']) : array($config['ldap_uid'], $config['ldap_email']),
                    0,
                    1
            );
Changed To:

Code: Select all

   	 $search = @ldap_search(
                    $ldap,
                    $config['ldap_base_dn'],
                    ldap_user_filter($username),
                    (empty($config['ldap_email'])) ? array($config['ldap_uid']) : array($config['ldap_uid'], $config['ldap_email'], 'displayName'),
                    0,
                    1
       );
Basically as I read that statement
"If they haven't specified which field is email, just load username, otherwise load username, email (and now full name)"


We'll want to pull the username from the table from now on.

Original ~line 180

Code: Select all

    $sql ='SELECT user_id, username, user_password, user_passchg, user_email, user_type
Changed To:

Code: Select all

    $sql ='SELECT user_id, username, user_password, user_passchg, user_email, user_type, user_from
But most importantly we'll need to save it on the user's first login for future retrieval.

Original ~line 226

It worth noting this will only be applied to new users authenticating against LDAP. Existing users (like you most likely) will need to manually change the Full Name value in your profile (after making all these changes)

Code: Select all

    $ldap_user_row = array(
         'username'              => $username,
         'user_password' => phpbb_hash($password),
         'user_email'    => (!empty($config['ldap_email'])) ? $ldap_result[0][$config['ldap_email']][0] : '',
         'group_id'              => (int) $row['group_id'],
         'user_type'             => USER_NORMAL,
         'user_ip'               => $user->ip,
      );

Changed To:

Code: Select all

 
    $ldap_user_row = array(

    'group_id'              => (int) $row['group_id'],
    'user_type'             => USER_NORMAL,
    'user_ip'               => $user->ip,
    'user_from'             => $ldap_result[0]['displayname'][0],
    );

    if ($guest_username === false)
            {
           $username = ($username) ? $username : $user->lang['GUEST'];

Changed To:

            $db->sql_freeresult($result);
            }
This is different then the code by Paul as it allows existing users to still be visible under their username if they have not yet added a Full Name. Otherwise administering old users becomes impossible!


File:- viewtopic.php

line ~1409
Original

Code: Select all

  $postrow = array(
    'POST_AUTHOR_FULL'              => get_username_string('full', $poster_id, $row['username'], $row['user_colour'], $row['post_username']),

Changed To:

Code: Select all

    $postrow = array(
'POST_AUTHOR_FULL'		=> get_username_string('full', $poster_id, $user_cache[$poster_id]['from'], $row['user_colour'], $row['post_username']),

This will keep the username clickable and colored!


This part just changes the reference of Location to Full Name

File:- /language/en/common.php
Original

Code: Select all

    'LOCATION'   => 'Location',

Changed To:

Code: Select all

    'LOCATION'   => 'Full Name',
