ServiceManager could not locate ZfcUserLdap\Authentication\Adapter\Ldap

[aarbrown]

Hello,

I followed your instructions in the README, although I was unsure of how to properly set up the ZfcUserLdap\Authentication\Adapter\Ldap so that the ServiceManager could get it. I ended up adding this to config/autoload/local.php: ... 'factories' => array( ... 'ZfcUserLdap\Authentication\Adapter\Ldap' => function ($sm) { return new ZfcUserLdap\Authentication\Adapter\Ldap; }, ... )

It seems to be working (though I am getting a fatal error which I believe is a separate issue). Is this how you would recommend setting it up?

Thanks

[Nitecon]

The service requires zfcuser, within the zfcuser config file is where you specify the use of the adapter itself. In the readme I note the following:

ZfcUser Configuration

For the initial release please make sure to set the following settings in your zfcuser configuration:

array(
    'enable_registration' => false,
    'enable_username' => true,
    'auth_adapters' => array( 100 => 'ZfcUserLdap\Authentication\Adapter\Ldap' ),
    'auth_identity_fields' => array( 'username','email' ),
),

The zfcuser configuration is separate from zfcuser-ldap module and you need to configure that part for this module to work as it is an addon to zfcuser, so to sum things up quickly what you will need to do is:

copy vendor/zf-commons/zfc-user/config/zfcuser.global.php.dist to config/autoload/zfcuser.global.php then open the file and edit it as per the instructions above. Thats all you need to do beyond setting the ldap array key and values for your ldap server as per the readme instructions.

[aarbrown]

It looks like my problems were due to my application.config.php. I changed it the order so that ZfcUserLdap loads after ZfcUser and it seems to be working. I thought I had already tried this configuration but I may have also had some ZfcUserLdap configuration errors at that time. Everything is working as expected now. Thanks for the great module!

[trainerbill]

I am getting the same error. I followed the directions except I just did a git clone of the repo to vendor/ZfcUserLdap. Do I have to use the composer.phar to install this module? I am also new to ZF2 so any help/explanations would be appreciated.

Putting 'ZfcUserLdap\Authentication\Adapter\Ldap' => 'ZfcUserLdap\ServiceFactory\LdapServiceFactory', in global.php under factories fixes the exeption. But I am still unable to authenticate so I'm not sure if it is still a problem.

I am now getting the error: Missing argument 2 for ZfcUserLdap\Service\LdapInterface::authenticate() in /home//git/ZendMVCTutorial/vendor/ZfcUserLdap/src/ZfcUserLdap/Service/LdapInterface.php on line 123

[aarbrown]

Hi trainerbill,

The problem in my situation was that I loaded ZfcUserLdap before loading ZfcUser in my zf2-app/config/application.config.php. I should have loaded ZfcUserLdap after ZfcUser (as Nitecon has noted in the Readme)

array( 'ZfcUser', 'ZfcUserLdap', /* It's important to load ZfcUser before ZfcUserLdap as ZfcUserLdap is an addon to ZfcUser */ );

hope that helps

[trainerbill]

Yeah I double checked that:

<?php return array( // This should be an array of module namespaces used in the application. 'modules' => array( 'Application', 'ZfcBase', 'ZfcUser', 'ZfcUserLdap',

),

[aarbrown]

Remove this bit 'ZfcUserLdap\Authentication\Adapter\Ldap' => 'ZfcUserLdap\ServiceFactory\LdapServiceFactory' from your global.php and double check your ldap credentials (the username / password and baseDn in particular).

You could also check the data/logs/ldap.log file if you are indeed failing ldap auth.

[trainerbill]

Still saying: ServiceManager could not locate ZfcUserLdap\Authentication\Adapter\Ldap. I don't get any files in root/data/logs/

Thanks for the help btw.

[trainerbill]

I validated my connection information:

$options = array(MY_OPTIONS); $ldap = new Zend\Ldap\Ldap($options); if($ldap->bind()) echo 'Bound'; else echo 'Unbound';

So my connect information is correct but I am still getting the error: Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for ZfcUserLdap\Authentication\Adapter\Ldap. Any ideas @Nitecon

[witt]

Same here! I think I'm getting the same error as @trainerbill

Zend\ServiceManager\Exception\ServiceNotFoundException File: /var/www/skeleton/vendor/zendframework/zendframework/library/Zend/ServiceManager/ServiceManager.php:496 Message: Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for ZfcUserLdap\Authentication\Adapter\Ldap

I did follow all the instructions. I used Composer to add:

• Installing zf-commons/zfc-base (v0.1.2) Loading from cache
  • Installing zf-commons/zfc-user (dev-master 0.1.2) Cloning 0.1.2
  • Installing nitecon/zfcuser-ldap (dev-master 9bd2c5f) Cloning 9bd2c5f8a62d35f96032ac15e21b11b7eb287931

Any ideas?

[Nitecon]

I am currently on paternity leave I'll take a look as soon as I have some spare time

[witt]

@Nitecon thanks and congrats!

[GehringerFlorian]

Hi I've got the same problem ( unable to fetch or create an instance for ZfcUserLdap\Authentication\Adapter\Ldap). But I think it depends on "bjyoungblood/BjyAuthorize": "1.2.*": When I remove BjyAuthorize from modules It seams to work. But I don't want to remove BjyAuthorize. Any suggestions?

[aarbrown]

@GehringerFlorian - I am using BjyAuthorize and I don't have any issues with ZfcUserLdap. I'm not sure why it would be breaking yours.

[trainerbill]

@GehringerFlorian @aarbrown Can you guys explain your setup and how you got this working? I am running Apache PHP on Debian with the php-ldap module installed. I cloned the skeleton application, then cloned the ZfcBase, ZfcUser, and ZfcUserLdap modules into the vendor directory. I followd the rest of the setup documentation. I can manually create an LDAP adapter and successfully bind.

[seg7]

Also have the same problem: Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for ZfcUserLdap\Authentication\Adapter\Ldap

Server configuration is loaded in ZDT, binding manually also works. No logs written.

[amajot]

I've been struggling with this exact same issue for about a week now but I think I solved the issue, can you guys see if you can replicate?

In the getServiceConfig() method inside of Module.php add this in the array:

'invokables' => array( 'ZfcUserLdap\Authentication\Adapter\Ldap' => 'ZfcUserLdap\Authentication\Adapter\Ldap', ),

I guess something changed in either ZF2 or zfcuser in the past couple months that requires that to be explicit or something? not sure ....

[seg7]

Adding that code all i get is a blank page...

[trainerbill]

@commiejim Yeah I tried that a couple weeks ago. It does get you past the service manager issue but it still errors out with some sort of authenticate error. You will find the exact error in your apache error log, I can't remember what it is. I am not sure if that error is in addition to the service manager error or a result of the workaround.

[amajot]

Strange, after I added what I said above it is working like a dream? Writes to the ldap.log file, and i've tailed apache error logs and its showing nothing. I can authenticate successfully with my LDAP server and it all seems vanilla.

Do you have the PHP LDAP extension installed? I had that issue a while back but installed it and its fine after that.

[seg7]

yes of course, otherwise i would be unable to bind manually. nothing appears on data/logs, zf is version 2.2.0. Just to clear it up what Module file did you modified? vendor/zf-commons/zfc-user/Module.php or vendor/nitecon/zfcuser-ldap/Module.php

Also i have not configured anything besides the required values in zfcuser...

there is also a problem with the route after i installed the ldap plugin was working fine before having only zfcuser.

The requested URL could not be matched by routing

Not commenting the zfcuser-ldap out of the config, i still have the problem (i have AllowOverride All in apache's vh set for the redirects)

[amajot]

Forgot that you mentioned that you could bind manually, my bad.

I have the same zf version as you too

I edited: vendor/nitecon/zfcuser-ldap/Module.php

Not sure what the routing issue could be, I didn't run into that. All I did was just move the zfcuser.global.php.dist file into the root ZF config/autoload, removed the .dist at the end, and did was was in the instructions.

[seg7]

yeah, well i tried both files and it gives me the same :(

can u up your singleton app somewhere so i could compare it with mine?

[Nitecon]

I have a few minutes so I'm going to test a couple of my applications that are using this to make sure the fix that @commiejim noted works across the board and will put in a new commit for this regarding it. There has been similar stuff like this that has happened in the past and I will most likely start setting the composer libraries to work with specific versions of zf2 only so that this doesn't become a problem again.

[trainerbill]

That fix seems to work for me.

[Nitecon]

So far I haven't been able to replicate the problem yet, I did however update to the latest dev-master of zf2 but still no issues as listed above. I am going to try it with bjyoungblood/BjyAuthorize to see if I can replicate the problem. I will also create a seperate demo repository for use so you can verify your settings against what I currently have.

[seg7]

Ok finally got it working with the fix, now is there possible to configure the basedn so it searches the entire subtree (scope)? Right now it only works if i point it to where the user is located.

[GehringerFlorian]

commiejim's fix solves my "...ServiceManager::get was unable to fetch or create ..." problem. Thanks a lot!

I'm using MS Active Directoy so I had to change some things:

vendor\nitecon\zfcuser-ldap\src\ZfcUserLdap\Service\LdapInterface.php

public function findByUsername($username)
 {
    try {
        $this->bind();
    } catch (\Exception $exc) {
        return $this->error;
    }
    try {
        $hm = $this->ldap->search("sAMAccountName=$username", $this->active_server['baseDn'], \Zend\Ldap\Ldap::SEARCH_SCOPE_ONE);
        foreach ($hm as $item) {
            $this->log($item);
            return $item;
        }
        return FALSE;
    } catch (LdapException $exc) {
        $msg = $exc->getMessage();
        $this->log($msg);
        return $msg;
    }
}

vendor\nitecon\zfcuser-ldap\src\ZfcUserLdap\Mapper\User.php

public function findByEmail($email)
{
    //...
    $this->entity->setId(0); //ToDo: Find Solution to work with Entity ...
    $this->entity->setUsername($obj['samaccountname']['0']);
    //...
}

public function findByUsername($username)
{
    //...
    $this->entity->setId(0); //ToDo: Find Solution to work with Entity ...
    $this->entity->setUsername($obj['samaccountname']['0']);
    //...
}

Now I'm able to Login. data\logs\ldap.log -> 2013-05-23T15:11:10+02:00 DEBUG (7): XXX logged in successfully!

But how can I get it working with the User-Entity? I'm using ZfcUserDoctrineORM.

bjyoungblood/BjyAuthorize says "403 Forbidden"

[GehringerFlorian]

Any errors in data\logs\ldap.log?

[GehringerFlorian]

Hi I think it works now for my special purpose using ZfcUserDoctrineORM AND MS Active Directory.

This is not deeply tested code! It's just a suggestion.

I did the following changes to the code:

Greetings from rainy Germany Florian

[Nitecon]

The module was never developed to handle active directory in the entity manager as I don't have an AD server to test / dev against. But it's something that will be in the works in the near future. For now I will add in the commit as suggested by adding the invokables.

[Nitecon]

Closing this issue as it appears the fix as per @commiejim has provided the permanent fix. Next up will be working on making zfcuser-ldap available on active directory as well as providing the ability to specify your own user mapper.

[m1st0]

With @GehringerFlorian 's changes for Active Directory, I got it working on my part except for the setId porton on line 42 and 55 of "vendor\nitecon\zfcuser-ldap\src\ZfcUserLdap\Mapper\User.php" as he had it:

$this->entity->setId(0); //ToDo: Find Solution to work with Entity ...

I found the following solution which cleared up "NOTICE (5): Undefined index: uidnumber {"errno":8,"file":".../vendor/nitecon/zfcuser-ldap/src/ZfcUserLdap/Mapper/User.php","line":55}"

 $this->entity->setId($obj['dn']['0']);

The notice is cleared, but I have a way to go. It appears successful in the log file returning all the correct LDAP info, but the "/user/login" page still relates "Authentication failed. Please try again." I got the idea from https://www.drupal.org/node/1899336 .

• I apologize that this does not help with 1.1.0, and dev-master has more changes than I had taken into account. If it is otherwise useful, I have also tried "setUsername($obj['samaccountname']['0'])" in hopes of quickly fixing 1.1.0 for Active Directory. There is no success right now for my attempts at Active Directory with zfcuser-ldap unless I manually just write a class to connect.
