I tried to set the ACL's over NFS with the 1.76 open-e nas enterprise version and I still have the same problem:setfacl -m u:emc:w test.acl. The system answer is : setfacl: test.acl: Opération non supportée (not permited). My nfs client is a Debian sarge with 2.6.8 kernel. The acl's are working locally but not over nfs. Do you have an idea or can you tell me which linux distrib and kernel could do the trick ?

If you get no answer here, this is probably where you will get an answer to that question, over on Wilders
