Dear Maintainer,

*** Reporter, please consider answering these questions, where appropriate ***

I am trying to use NFSv4.1 mounts and ACL's on Debian 9, but I
Cant set NFSv4 ACL for a particular user - other users work fine.... that user id seems to be fine....

here is the behavior:

root@ika:/net/proj# nfs4_setfacl  -a A::kurian@netid.washington.edu:rwx /net/proj/SHAMPnetdat
Failed setxattr operation: Invalid argument

root@ika:/net/proj# mount | grep proj
tako:/export/nfsv41_proj on /net/proj type nfs4 (rw,relatime,vers=4.1,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=172.28.43.150,local_lock=none,addr=172.28.43.175)
root@ika:/net/proj#

root@ika:/net/proj#

root@ika:/net/proj# getent group shampnetdat
shampnetdat:*:471122:dth2,morrism,mbw,kurian


This is bizarre... is there any better error message that can be produced?

NFSv41 file server is an Oracle ZFSSA Z3-2 Appliance

thanks,
Matt
