[Bug 925364] Re: rpc.gssd exits immediately

I don't user Kerberos.  However, If I don't want a long wait when
mounting NFSv4 shares, I must enable this on the client.  It results in:

Nov  2 13:31:50 poogoo rpc.gssd[2342]: ERROR: gssd_refresh_krb5_machine_credential: no usable keytab entry found in keytab /etc/krb5.keytab for connection with host fit.thepratts.info
Nov  2 13:31:50 poogoo rpc.gssd[2342]: ERROR: No credentials found for connection to server fit.thepratts.info

But the mount occurs very quickly and seems to be ok.

There should be a way on the client side to state that Kerberos is not
being used.

Title:
  rpc.gssd exits immediately

Status in “nfs-utils” package in Ubuntu:
  Triaged

Bug description:
  Release: Precise Pangolin 12.04 Alpha
  Version:  1.2.5-3ubuntu1 (nfs-common)

  Starting rpc.gssd initially appears to launch ok

  root at cisadl-tst:~# status gssd
  gssd stop/waiting
  root at cisadl-tst:~# start gssd
  gssd start/pre-start, process 3624
  root at cisadl-tst:~# status gssd
  gssd stop/waiting
  root at cisadl-tst:~# 

  
  Running rpc.gssd in the foreground manually also seems to exit immediately with status code 1

  root at cisadl-tst:~# rpc.gssd -fvvv ; echo $?
  beginning poll
  1

  Expected behaviour:   rpc.gssd starts and allows Kerberized NFS to work
  Observed behaviour:   rpc.gssd exits immediately and Kerberized NFS fails.

  I have attached the output of strace -f against rpc.gssd if it is of
  any help.
