[SSSD] [PATCH] NSS: Set UID and GID to negative cache after searching all domains

[Jakub Hrozek]

Hi,

the first patch fixes the bug that Jean-Baptiste Denis found earlier
today. In case the lookup was not done using a FQDN, the code would skip
setting the entries to the ncache.

The second patch is an incremental improvement. I don't think we should
abort the whole lookup if setting an entry in negcache would fail. The
negative cache is a performance optimization after all.
