Add `auto_bind` config option

See original GitHub issue

Bug description

Make ldap3 library auto_bind config settable.

Expected behaviour

Currently, if use_ssl is set to False, auto_bind becomes ldap3.AUTO_BIND_TLS_BEFORE_BIND. This means that the ldap server must support ssl or starttls. There is no way to use a ldap server which doesn’t have either. This is the case for a local LDAP server i.e runs in the same server as jupyterhub and communicates via the internal network.

Actual behaviour

Add a new config variable auto_bind to match upstream ldap3 library configuration.

I opened this as a bug because it used to because this was the behavior in 1.3.0 but it seems behavior changed because of the discussion in https://github.com/jupyterhub/ldapauthenticator/issues/171

How about something like:

if self.auto_bind:
    auto_bind = self.auto_bind
else:
    auto_bind = (
        ldap3.AUTO_BIND_NO_TLS if self.use_ssl else ldap3.AUTO_BIND_TLS_BEFORE_BIND
    )

I somehow missed @1kastner 's comment. I will submit a PR. We use JupyterHub in the Cloudron app, so I have a test setup handy.
