[NFS-Ganesha-Support] Re: Proxy-v4 access denied

You config looks like it should work, however, do you gave ID Mapper configured identical on all three hosts involved (client, Ganesha server, proxied server)? Could you share you network traces (both between client and Ganesha and between Ganesha and the proxied server)? Could you share the debug log? You could add NFS4_ACL to log the permission checking which might help. On the idmapper stuff, you need to determine if the owner/group attributes coming from the server are in the form "user@domain" or "1234". You may need to set NFS4 { Allow_Numeric_Owners = true; } in your config if the owner/group attributes are numeric. The parameter Only_Numeric_Owners will cause Ganesha to issue owners in the form "1234" instead of "user@domain" for client side GETATTR and proxy side SETATTR (and OPEN/CREATE). There are kernel NFS parameters that control this also for client and I believe the server. I'm going to bet that idmapping issues are the cause here. I hope the above gives you enough to go on to fix the issue if that's the case. Frank
