1. Using "-USE_NFSIDMAP=OFF" compile argument.

2. UseGetpwnam set to false and allow_numeric_owners to true in the nfsv4 configuration

This eliminated the user lookups for the most part, but we occasionally noticed that when doing a chown to a uid that the client didn't know, that was getting passed to ganesha as a uid and ganesha was then interpreting this as a user name and trying to do a name to id lookup via name2id method in /idmapper/idmapper.c which does a getpwam call that is not checked for the configuration options like other similar calls. Is this a bug that it is doing a getpwnam_r even though UseGetpwnam is set to false? Additionally, why does ganesha ever need to lookup users by name? I'm surprised that it would ever get user names from a client and wouldn't need to do a name to id lookup. The chown is passing an id in this case. We are using ganesha 2.5.5.
