Hi all, I was trying the NFS idmapping functionality by creating users with same name but different IDs and was getting strange results the ls commands would show me the proper output but the chown command would fail. On searching the internet, I found this link http://dfusion.com.au/wiki/tiki-index.php?page=Why+NFSv4+UID+mapping+breaks+with+AUTH_UNIX The link basically mentions that for the authentication (identifying the executor of the command) it uses SunRPC and that sends uid, gid in integers (Not as names) Thus chown does not work as the IDs on server and client differ. Is there a plan to have the RPC layer send names too, so that NFSv4 idmapping will work in the case of AUTH_UNIX? Also is it reasonable overriding the logic in https://github.com/torvalds/linux/blob/29fbff8698fc0ac1a1d74584b258e0bf18b469f9/net/sunrpc/auth_unix.c#L130 to consider a fixed offset (in case of unprivileged containers the UIDs are offseted by some fixed offset like 10000) will address the issue?
