Hi,
What does this message mean?
```auto

It means that the configuration for the LDAP connection is not working.

We normally connect to the server. But with every login we get this message.

Well I guess you authenticate with another method than LDAP but you have LDAP configured as one of the authentication method but it is failing to connect to the server.

Can you tell me, please, where is the configuration file for LDAP connection?

In the trytond configuration under the [section [ldap\_authentication]](https://docs.tryton.org/projects/modules-ldap-authentication/en/latest/).

Here is our section:
```auto
[ldap_authentication]
uri = ldap://ldap:389/ou=People,dc=ilt,dc=ua?uid?onelevel
```
What’s wrong with it?

I can not say. But it is not enough to bind to your LDAP server. Maybe you need a `bind_pass`.

We have set the `bind_pass` password. Nothing changed. The message `unable to bind` remains.

Maybe you need to define a `bindname`.
You should read the [ldap3 documentation](https://ldap3.readthedocs.io/en/latest/) to learn the correct way to connect to your LDAP server.
