Title:
  nfs-utils/nfs-kernel-server (rpc.svcgssd) ignored /etc/nfs.conf
  settings

Status in nfs-utils package in Ubuntu:
  New

Bug description:
  Tested on:
   Ubuntu 22.04 (x86_64)
   Package: nfs-kernel-server 1:2.6.1-1ubuntu1

  Set config options in /etc/nfs.conf are ignored by rpc.svcgssd
  (required for krb5 NFSv4).

  I was trying to set the principal name like:

  [svcgssd]
  principal=nfs/myhost.mydomain.de at MYDOMAIN.DE

  but rpc.svcgssd refused to start. When specified on command line
  (using the -p option) things started working.

  After having a look at the code (nfs-
  utils-2.6.1/utils/gssd/svcgssd.c), the problem seems to be

          /* We don't need the config anymore */
          conf_cleanup();

  which is called too early. So at the point where gssd_acquire_cred()
  is called the variable "principal" does no longer contain the data
  read from the config file.

  Moving conf_cleanup() to the end of the code helps.

  I also tried to get into contact with the nfs-utils developer
  themselves - but I hope someone at Ubuntu has a better way to contact
  them.
