Subject: [PATCH 195/195] cache_req: Look for name attribute also in

 nss_cmd_getsidbyid

MIME-Version: 1.0

Content-Type: text/plain; charset=UTF-8

Content-Transfer-Encoding: 8bit

We always check negcache after getting data from backend since commit

4c09cd008967c5c0ec358dc658ffc6fc1cef2697 because we usually do have a name

in begging of requests "* by ID".

We were not interested in name in request sid by id before. However, function

cache_req_search_ncache_filter always expect name otherwise it returns

ERR_INTERNAL.
