Has anybody successfully used ACLs over NFS (v3 or v4)? I can read them with getfacl, but setfacl always gives "Operation not supported". ACLs work fine when accessing the underlying ext3 partitions directly.
An afternoon of searching has yielded startingly little information other than that, in 2003, some special patches were needed. There's a lovely guide at
http://www.vanemery.com/Linux/NFSv4/...no-rpcsec.html, but the author does not show ACLs being used over NFS so I can't consider that conclusive evidence. man pages don't say anything about it that I could find.
Are there known issues here? Am I the only one trying to do this, or is it working for the rest of the world?
