  Hello list,
  
  I found a lot of information on the subject NFS server, ipv6 + krb5, but
  not anything conclusive. So I tried it out; I got IPv6 +
  NFS4 to work, but only with sec=sys.
  
  When using sec=krb5, there seemed to be errors in gssd communication.
  (Ubuntu 10.04 with rpcbind instead of portmap; with nfs-utils-1.2.3 from
  nfs.sf.net, and with a 2.6.35-020635rc1-generic kernel package).
  
  Is this correct, i.e. svcgssd still needs to be adapted to IPv6? Or
  should NFS-server/IPv6/Kerberos on Linux just work, i.e. should I
  re-check my configuration?

I don't know the specific answer to your question, but ipv6 support is still
a work in progress, and I'm actually a bit surprised it works out of the box
even with sec=sys.

You may want to try the very latest ipv6 version of nfs-utils, which may
have some patches that have not yet been merged upstream.  You can get it
from git://git.linux-nfs.org/projects/cel/nfs-utils.git .  The usual
warnings apply, this is experimental code, you could lose data, it may not
work with your 2.6.35 kernel, and if you find bugs you can't necessarily get
anyone to help you.
