FR3DLdapBundle - Authentication request failed

Question

I'm using FR3DLdapBundle with FOSUserBundle.

Symfony Version 3.2.6 FR3DLdapBundle Version 3

config.yml

fos_user:
    db_driver: orm # other valid values are 'mongodb' and 'couchdb'
    firewall_name: main
    user_class: AppBundle\Entity\User
    from_email:
        address: "%mailer_user%"
        sender_name: "%mailer_user%"

fr3d_ldap:
    driver:
        host: ldap.forumsys.com
        port: 389
        username: cn=read-only-admin,dc=example,dc=com
        password: password
        bindRequiresDn: true
    user:
        baseDn: dc=example,dc=com
        filter: (&(objectClass=person))
        attributes:
            - { ldap_attr: uid,  user_method: setUsername }

security.yml

encoders:
    FOS\UserBundle\Model\UserInterface: bcrypt
    AppBundle\Entity\User: plaintext

erase_credentials: false

role_hierarchy:
    ROLE_ADMIN:       ROLE_USER
    ROLE_SUPER_ADMIN: [ROLE_USER, ROLE_ADMIN]

providers:
    chain_provider:
        chain:
            providers: [fr3d_ldapbundle,fos_userbundle]

    fr3d_ldapbundle:
        id: fr3d_ldap.security.user.provider

    fos_userbundle:
        id: fos_user.user_provider.username

access_control:
    - { path: ^/login$, role: IS_AUTHENTICATED_ANONYMOUSLY }
    - { path: ^/, role: ROLE_USER }

I test the service with the Online LDAP Test Server . I have managed to make an successful login with the following config:

fr3d_ldap:
driver:
    host: ldap.forumsys.com
    port: 389
    #version: 3
    username: cn=read-only-admin,dc=example,dc=com
    password: password
    bindRequiresDn: true

user:
    baseDn: uid=euclid,dc=example,dc=com
    filter: (&(objectClass=person))
    attributes:
        - { ldap_attr: uid,  user_method: setUsername }

But the Problem with this config i can only login as the user euclid. But i want to login as every available user.

But with the other config i get the message in the log, that the user was found but an expetion has occurred.

I dont know what i do wrong and i am at my beginnings with LDAP.

EDIT I have changed my code like the example Alvin has posted. But i get the following error: Symfony Dev Log . The system founds the user but then i get the errors in the log file.

Answer 1

you just need to change your baseDn like so:

user:
    baseDn: dc=example,dc=com

I think that should do it.

EDIT # 2 - based on feedback

This was the solution to add this to the FOSUser.php Entity as per my tutorial:

/**
  * {@inheritDoc}
  */
public function setDn($dn){
    $this->dn = $dn;
}

/**
  * {@inheritDoc}
  */
public function getDn(){
    return $this->dn;
}

Reference to my tutorial here: https://alvinbunk.wordpress.com/2016/03/25/symfony-ad-integration/

Answer 2

So i finaly found the problem in my code.

I forgot to set the set and get function for the DN field in the User Entity correctly. That was my code:

/**
 * Set Ldap Distinguished Name.
 *
 * @param string $dn Distinguished Name
 */
public function setDn($dn)
{
    // TODO: Implement setDn() method.
}

/**
 * Get Ldap Distinguished Name.
 *
 * @return null|string Distinguished Name
 */
public function getDn()
{
    // TODO: Implement getDn() method.
}

But that is the correct one from Alvins tutorial :

 /**
 * {@inheritDoc}
 */
public function setDn($dn)
{ $this->dn = $dn; }

/**
 * {@inheritDoc}
 */
public function getDn()
{ return $this->dn; }

Thank you Alvin for your help and the awesome tutorial .
