15 Well, at east the sed man page in german is quite different from the
16 englisch one, maybe that's the case here, too. Does yours explain the
17 (no_)subtree_check option? I had t look them up online.

21 1.1.4-r1.

23 Bug #116269 from end of 2005 misses the rpc.ugidd, the answer there is that
24 nfs-utils does not yet support it. And I doubt it ever will, I just read
25 that this is a feature of user space NFS, which seems to be deprecated. A
26 kernel based NFS does not have it.
27
28 So, so seem to be right, ID mapping just is not possible (any more).
29
30 But what about NFS v4? Is has user authentification, maybe then there's a
31 mapping feature, too?
