Hi,
I have two queries
1. I am trying set ACL on file over NFS v4 but its failing ,
with error permission denied ( NFS4ERR_BADOWNER) . I am not able to
figure out the problem area.This is against Netapp filers,
and all server side options are set properly for NFS access.
2. On linux the NFS v4 mount of same NFS share shows, the
file UID/GID as nobody for all files ?? why ?

Any help on this is highly appreciated.
thanks & regards
