This is probably caused by user "root" being mapped to user "nobody" by
NFS. Also, the permissions on /tank only allow user "429496794" to
write to the /tank mountpoint. What is the ownership/group of /tank on
the Solaris host? The user 4294967294 looks suspicious.
Did you intend for root users to create files from your nfs clients? If
so, then you will need to share it to allow that sort of behavior.
