Dear Iñaki,


I have tried this version (ldap-clones-patch-script_3.0+_v2.zip) in my moodle server version 3.0. I am getting the following error when I try this patch.


[E6320@Qmoodles moodle_30]$ php -f ldapname.php ldaptmtl

!!! <p>Error: database driver problem detected</p>

<p>The site administrator should verify server configuration</p><p>PHP has not been properly configured with the MySQLi extension for it to communicate with MySQL. Please check your php.ini file or recompile PHP.</p> !!!


My moodle application is working fine without this MySQLi extension moodle will not function.


Kindly help


Regards,

Saravanan P

Hi Saravanan,

the error is probably due to the PHP command line interface configuration (php.ini) being different than your PHP web server module configuration (they sometimes use different configuration files for each of them).

Make sure you use the same configuration settings in both cases, and that you execute the command at the top of your Moodle installation directory.

Saludos.
Iñaki.

Hi Iñaki,

Just to let you know that ldap-clones-patch-scriptv16_27+.zip works perfectly with Totara 2.7.6 (Moodle 2.7.9). Thank you!

Regards,

Michael.

Hi Iñaki.

First of all I want to thank you for your contribution.

I am using Moodle 3.1 and was able to apply the patch.

The additional auth plugin was generated and I was able to install it, activate and configure it.

The issue I`m facing now is that I am not sure if I need to add a scheduled task for this in order to syncronize. When I execute the cron job I only see messages for the first original plugin, but not from the second one added. Is this task necesarry? If yes, How can I add it?

In Scheduled tasks I only see this:

LDAP users sync job \auth_ldap\task\sync_task

This is what I see on cron execution:

Execute scheduled task: Trabajo de sincronización de usuarios LDAP (auth_ldap\task\sync_task)
... started 19:59:10. Current memory use 20.5MB.
Conectando con el servidor LDAP ...Creando la tabla temporal tmp_extuser..Obtenidos 2 registros de LDAPNo hay actualizaciones disponiblesNo hay entradas de usuarios para agregar... used 8 dbqueries
... used 0.56359791755676 seconds
Scheduled task complete: Trabajo de sincronización de usuarios LDAP (auth_ldap\task\sync_task)

Am I missing any configuration?

Thanks in advance for your help.

Tomas.

Yes, your duplicated ldap plugin will not be run through scheduled tasks.  You will need to set up a separate cron job on your server if you want it to sync automatically.

Thanks Emma for your prompt reply.

Excuse me for my ignorance: Can you point me to a document which specifies the steps to set up a separate cron job?

Regards.

Tomas.

That would depend on your server...at some point, you set up a cron job that pointed to admin/cli/cron.php or something similar.  Now you need add another line to that pointing to the sync.php or sync_users.php in your duplicated ldap plugin.

Thanks again Emma.

With your instructions I was able to execute the sincronization script directly from cli folder of the new LDAP plugin that I had generated.

Tomas.

Hi Tomas,

you are not missing any configuration, as Emma has pointed out.

On the other hand, it turns out that I didn't notice that the patch was failing to take into account the new scheduled tasks sub-system files. So the scheduled tasks were not being created for the cloned plugins.

I have updated the patch to take that into account. Bear in mind that the cloned plugin scheduled tasks are only created during plugin installation (that's the way Moodle behaves, not something patch-specific). So this won't benefit existing users much (unless you backup your cloned plugin settings, uninstall it, re-install it and restore your plugin settings).

I'm attaching updated patches for Moodle 3.1+ (current as of today), and Moodle master. I'll upload and update version for Moodle 3.0+ in a few hours.

Saludos.
Iñaki.

Re: How to use multiple LDAP servers with Moodle 1.8

We are successfully using the clone script with Totara 2.7.6 (Moodle 2.7.9). It works really well.


A problem we have is that sometimes users have duplicate names in the different domains:

Example (names anonymised):

ldap - domain1\jsmith1 (Jonathan Smith)

ldap2 - domain2\jsmith1 (James Smith)

Jonathan Smith logs in and their account in Moodle is created.

When James Smith comes along their account isn't created in Moodle and they are logged in as Jonathan Smith.


This is because the username must be unique.

Question 1:

Am I right in saying that there is no way to map or modify the username created to include some other attribute e.g. country code in the Moodle username?

It might solve the problem if the username was generated with the country code as a prefix:

e.g. uk_jsmith1, us_jsmith1 etc.

We are using NTLM so the username is derived from SAMAccountName.


I can't see how we could even customise the authentication plugin because in auth.php in user_signup() $user->username is already populated with no access to other properties such as countrycode (mapped to c in the Active Directory attributes).

Hi,

I'm a bit behind the promised schedule wink, but here go updated patches for Moodle 3.2 and Moodle master, current as of today.

I'll send patches for Moodle 3.0+ and Moodle 3.1+ in a second message, as I can't attach more than two files per message in this forum.

Saludos. Iñaki.

Hi Inaki

Your excellent work with the LDAP clones plugin has helped me a lot of the last year or so. I was wondering if you'd had a chance to create a new plugin for Moodle 3.2.2? I've tried the ldap-clones-patch-script_3.2_v1.zip and get the errors in the attached file.

Thanks

Darren

Hi Darren,

here's an updated version for Moodle 3.2.2+ (Build: 20170316). It also applies cleanly to 3.2.2 (Build: 20170313).

Hi Iñaki,

I've sent you a PM about this as well, but is there a possibility of a 3.3 patch?

It looks like everything has changed with the LDAP plugin in this release. Has anyone else encountered issues?

Kind regards, 

Anthony

Hi Monica,

I wanted to reply as you directed your message at me.

It's not something I would be able to help you with, but hopefully Iñaki or another can.

It looks like the settings.php file in 3.3 has superseded the config.html file in lesser versions, which is why the patching is failing. There is no config.html file anymore.

Hi,

I've been unable to get some spare time to work on this, but I finally managed to have some smile

Here are a couple of versions, one for 3.3, a second one for 3.3.1 (this one applies to 3.3 with just a warning about a single hunk, but i decided to create a separate one for 3.3).

Hope this helps.

Saludos. Iñaki.

Hi Iñaki, 

Thank very much for your time and the new version patch, it's going to be very useful for our site.

I've seen a small mistake I think: in version 3.3.1, at ldapname.diff you are using ldap2 instead of '/auth/'.$this->authtype.'...', so you get an error if you use a different name of ldap2 for the new ldap.

Thanks again, un saludo

Mónica
