FR3DLdapBundle - Binding requires username in DN form

Question

I'm using FR3DLdapBundle with FOSUserBundle.

Symfony 2.5.6

FOSUserBundle ~2.0@dev

FR3DLdapBundle ~2.0@dev

$ldapManager = $this->get('fr3d_ldap.ldap_manager');
print_r($ldapManager->findUserByUsername('[email protected]'));

But I catch one error.

Binding requires username in DN form 
CRITICAL - Uncaught PHP Exception FR3D\LdapBundle\Driver\LdapDriverException: "An error occur with the search operation." at myproj\vendor\fr3d\ldap-bundle\FR3D\LdapBundle\Driver\ZendLdapDriver.php line 55 

I have done everything in the installation documents

config.yml

        port:                389
        username:            [email protected]
        password:            password
        bindRequiresDn:      true
        baseDn:              dc=ldap,dc=example,dc=com
        accountFilterFormat: (&(uid=%s)) # Optional. sprintf format %s will be the username
    user:
        baseDn: dc=ldap,dc=example,dc=com
        filter: (&(ObjectClass=Person))
        attributes:
          - { ldap_attr: uid,  user_method: setUsername }

I don't get how to make this work.

Answer 1

We faced the very same issue when trying to make our internal auxiliary tool to work with corporate domain authentication.

We had to do the following to get it to work:

Even though fr3d documentation says this is for OpenLDAP only, we tried to set special auth account username in the following form under driver settings (instead of [email protected], and yes, our corporate LDAP is Microsoft AD):

config.yml

    fr3d_ldap:
        driver:
            host:                dns.example.com
            port:                389
            username:            CN=AuthAccount,OU=Pseudo Accounts,OU=Managed Objects,DC=example,DC=com
            password:            yourPassw0rd
            bindRequiresDn:      true

Note there is no baseDn at all (already set in username, otherwise further filtering will work incorrectly).

After that the issue is gone and the only thing left is to correctly set the user settings:

        user:
            baseDn: OU=Managed Objects,DC=example,DC=com
            filter: (&(sAMAccountName=%s))

Still have some work to do with attributes and so on, but with the above settings the LDAP auth itself started to work fine and we were able to log in to our tool with domain credentials.
