``uid=einstein,dc=example,dc=com``, then the ``dn_string`` will be
``uid={username},dc=example,dc=com``.

query_string
............

**type**: ``string`` **default**: ``null``

This (optional) key makes the user provider search for a user and then use the
found DN for the bind process. This is useful when using multiple LDAP user
providers with different ``base_dn``. The value of this option must be a valid
search string (e.g. ``uid="{username}"``). The placeholder value will be
replaced by the actual username.

When this option is used, ``dn_string`` has to be updated accordingly. Following
the previous example, if your users have the following two DN:
``dc=companyA,dc=example,dc=com`` and ``dc=companyB,dc=example,dc=com``, then
``dn_string`` should be ``dc=example,dc=com``. If the ``query_string`` option is
``uid="{username}"``, then the authentication provider can authenticate users
from both DN.

Bear in mind that usernames must be unique across both DN, as the authentication
provider won't be able to select the correct user for the bind process if more
than one is found.

Examples are provided below, for both ``form_login_ldap`` and
``http_basic_ldap``.
