    CACHE_REQ: Don't error out when searching by id = 0
    
    This code path can be easily triggered by calling `id 0` and SSSD should
    not error out in this case.
    
    Previous patches in this series already add uid and gid 0 to the
    negative cache and we can properly handle this situation.
