### Description of my issue
When attempting to enable LDAP auth for Pixelfed, I found out that no password appears to be required (see my [other post](https://forum.yunohost.org/t/how-to-obtain-the-ldap-password/24077/2)). However, using the same parameters, I get the following error message when running `php artisan ldap:test`:
```auto
ldap_bind(): Unable to bind to server: Server is unwilling to perform. Error Code: [53] Diagnostic Message: unauthenticated bind (DN with no password) disallowed
```
It seems that a password is, in fact, required, I just don’t know which one or how to access it.

This is now fixed ! Here is what I did:
I modified the config like this:
```auto
LDAP_LOGGING=true
LDAP_CONNECTION=default
LDAP_CONNECTIONS=default
LDAP_DEFAULT_HOSTS=127.0.0.1
LDAP_DEFAULT_USERNAME=""
LDAP_DEFAULT_PASSWORD=""
LDAP_DEFAULT_PORT=389
LDAP_DEFAULT_BASE_DN="dc=yunohost,dc=org"
LDAP_DEFAULT_TIMEOUT=5
LDAP_DEFAULT_SSL=false
LDAP_DEFAULT_TLS=false
```
The connection works when you put no username _and_ no password, so indeed no password was required. Then, I continued to follow the [guide](https://docs.pixelfed.org/running-pixelfed/optional-features/ldap-authentication/), but I had to replace:
```php
'model' => LdapRecord\Models\ActiveDirectory\User::class,
```
with
```php
'model' => LdapRecord\Models\OpenLDAP\User::class,
```
I don’t understand why this isn’t mentioned in their guide, but after this I can run `php artisan ldap:import users` and it will see and be able to synchronize them.
The issues I’m facing now are:
- the auth system does not work, as in, imported users cannot sign in, apparently because the passwords can’t be matched with the database
- the imported users don’t have a username when running `php artisan user:table`, the `uid` property is not synchronized

what was the config file /location you changed? this looks to be very similar to the problem I’m having: [Adding catchall problem - #3 by sadmin](https://forum.yunohost.org/t/adding-catchall-problem/24424/3)
