Do you have the exact same idmapping on both clusters? That might be
one reason for access denied. Do the autorid ranges match? You might
try to look at mmgetacl output on both sides. Also, keep in mind that
only -k nfs4 is really tested in the gpfs samba backend, if you have
-k posix or -k all (any?), additional development is likely necessary.
