If it's related to the ACL handling then it should start working when
you remove the ACL on the file with 'setfacl -kb …'.  On the other hand
you mentioned NetApp, and these can be set up to completely ignore
certain DACL, mode or owner changes from clients (with or without
raising errors while doing so).
