Unable to auth user with a NoDatabaseUserProvider

[MoiseScalzo]

• Laravel Version: 5.7
• Adldap2-Laravel Version: 5.1
• PHP Version: 7.2
• LDAP Type: ActiveDirectory

Description:

I'm trying to login with email address (as userprincipalename) and password in a NoDatabaseUserProvider configuration but the Auth::attempt() return always false. On the other hand, Adldap::auth()->attempt($request->userprincipalname, $request->password, $bindAsUser = true); it return true and also Adldap::search()->findBy('userprincipalname', $username) works correctly. So, where I'm wrong? :(
thank you in advance

UPDATE:
maybe I've solved changing this:

'ldap' => [
'discover' => 'userprincipalename',
'authenticate' => 'password'
]

to this:

'ldap' => [
            'discover'     => 'userprincipalname',
            'authenticate' => 'userprincipalname',
        ],

can you confirm that is the right way?

Hi @MoiseScalzo,

This is definitely the right way when using ActiveDirectory. The authenticate value is what to use as the users username when calling ldap_bind() on your configured LDAP connection. Setting it to password won't work.

For example, in ActiveDirectory, a users Distinguished Name or User Principal Name can be used as a username to bind to ActiveDirectory servers:

// Using UPN:
$userPrincipalName = 'jdoe@acme.org';

ldap_bind($conn, $userPrincipalName, 'secret-password');

// Using DN:
$dn = 'cn=John Doe,ou=Users,dc=acme,dc=org';

ldap_bind($conn, $dn, 'secret-password');

So you can actually use either distinguishedname or userprincipalname as the value for the authenticate option. They will both work.

I hope I made it more understandable!

Are you able to successfully login now?

Hi, @stevebauman thank you very much for the clarification. Now login works correctly.
Thanks
