Dipit Grover has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1177645?usp=email ) Change subject: Idmapper: Introduce negative cache for user entries ...................................................................... Idmapper: Introduce negative cache for user entries This change introduces a negative cache for storing user entries that failed idmapping. The validity and max-count of such entries is derived from the DIRECTORY_SERVICES section of the Ganesha config. This cache is maintained separately from positive cache, to allow for independent operation, configuration and maintenance. Note that we do not store the anonymous uid and gid resolved for such entries, because these resolved ids for a given entry can vary across different incoming nfs op-requests. Each request uses the anonymous uid,gid configured for the respective client's export that is being accessed.
