s3-winbindd_ads: prevent negative GM/ cache entries due to broken connections
The ads lookup_groupmem() function calls lda_lookupsids to resolve sids to names. This is tried only once. So in case the connection was broken, e.g. closed by the server (without a reset packet), there will be an empty GM/ cache entry for the requested group which will prevent proper working of access checks among other checks for the expiry period. This patch works around this problem by retrying once if the lsa_lookupsids call fails, re-establishing the dc-connection, as we already do in many other places (e.g. the winbindd retry methods for the rpc layer).
