    users (Tracker ID:2922729)

    (Tracker ID:3006096)
[-] Bug fix: Return false for user_info if the user does not exist
[-] Bug fix: user_info, checks for for a "count" value that not exist in
    $entries array if "memberof" isn't passed in $fields array. (Tracker
    ID:2993172)
[-] Bug fix: In authenticate() if user authentication fails function
    returns and does not rebind with admin credentials - so the other
    funcions don't work anymore as $this->_bind === false. (Tracker
    ID:2987887)
[-] Bug fix: When calling $ldap->user_modify('user',
    array("expires"=>0)) the function fails due to the value being 0.
