[Bug 1373490] Re: NFS4, NFS stopped working after 12.04 to 14.04 upgrade

[Joni-Pekka Kurronen]

hi,

Real Bug is that NFS logging dose not give clear information wgat's
happening and diagnose is hard to do!

Problem solved:
1) I finaly found upgrade kernel, after installing it gssapi error
message dissapeared and NO ERROR MESSAGES at log's.

2) by useing wireshark I found _kerberos._udp DNS requests and
due DNS had not answers I configured BIND9 to publish all kerberos
service addresses.

I have NFS + MIT kerberos client and apacheDS LDAP + KERBEROS server
there is no addministration address at kerberos.

  after 12.04 to 14.04 upgrade it stopped to work and I belived it was
  pam/ldap realatd configuration problem,... can you kindly look at and confirm that this is the

  This is OK whit server, so principal should work,...
  sudo kinit -k -t /etc/krb5.keytab nfs/mpi1.kurrola.dy.fi at KURROLA.FI

  Client:
    MIT: kerberos client

  joni at kaak:~$ sudo mount -a
  mount.nfs4: access denied by server while mounting mpi1.kurrola.dy.fi:/

  and log says at client:

  Sep 24 18:37:53 kaak sudo: joni : problem with defaults entries ; TTY=pts/2 ; PWD=/home/joni ;
  Sep 24 18:37:53 kaak sudo: joni : TTY=pts/2 ; PWD=/home/joni ; USER=root ; COMMAND=/bin/mount -a
  Sep 24 18:37:53 kaak sudo: pam_unix(sudo:session): session opened for user root by joni(uid=0)
  Sep 24 18:37:54 kaak sudo: pam_unix(sudo:session): session closed for user root

  This at client work's do principals should be ok.
