In order to ensure consistent results of all error conditions returned
    by the LDAP server, the _authenticate() method should return `False`
    for every kind of exception, not just for INVALID_CREDENTIALS.

    This is not actually relevant in 12.0 as the result is exactly the
    same, due to the way the `entry` variable is being initialized, but it
    will make the code path "visibly consistent" across all supported
    versions
