Hello, I'm trying to set up a couple of Active-directory integrated Linux machines using NFS4 volumes on a NetApp Server as storage media. So far, I'm nearly there, but the final step seems to be missing: My client (Debian GNU/Linux with nfs-utils 1.2.5) can mount the NetApp Emulator and Users are managed completely by AD Objects using nslcd. Now I try to mount the NetApp Emulator vis NFS4 as root: mount -t nfs4 -o sec=krb5 dataontap-801.<fqdn>:/vol/v_testhome1/testhome1 /mnt/ This also works, however the NetApp is printing some strange warning: [nfsd.rpc.request.bad:warning]: Client 10.1.7.174 is sending bad rpc requests with error: RPC version mismatch or authentication error(73) [nfsd.auth.status.bad:warning]: Client 10.1.7.174 has an authentication error 2 This is probably harmless and caused by the local root which does not have a valid AD account. After the mount I can successfully browse the volume as user and my machine is even able to read/write files to/from the server. However the files are not owned by the correct users. Server is just sending me invalid stuff. Here is the owner string I get from the server looking into the packets using wireshark: ... recc_attr: FATTR4_OWNER (36) fattr4_owner: root@<fqdn> length: 19 contents: root@<fqdn> fill bytes: opaque data recc_attr: FATTR4_OWNER_GROUP (37) fattr4_owner_group: nobody length: 6 contents: nobody fill bytes: opaque data However checking with Windows and SMB these files are not owned by root but rather by the user which is trying to access the server. On a Linux machine I would now try to run the server side rpc.idmapd with verbose options, but unfortunately with NetApp I don't know exactly what to do. So, any hint what I am missing here? Client side userid mapping seems to work fine, as I can seen something like this wehen running rpc.idmapd in verbose mode: rpc.idmapd: Client 11: (user) name "root@<fqdn>" -> id "0" rpc.idmapd: Client 11: (group) name "nobody" -> id "65534" Regards Sven -- "A strategy for rewarding artists that regulates 'copies' makes as much sense in the digital age as a strategy for controlling greenhouse gases that regulates breathing."
