Thank you both for your help!

Check this out...

➜ ~ cat /etc/default/nfs-kernel-server
RPCNFSDCOUNT=8
RPCNFSDPRIORITY=0
RPCMOUNTDOPTS="--manage-gids"
NEED_SVCGSSD="yes"
RPCSVCGSSDOPTS=""

The entry 'NEED_SVCGSSD="yes"' is 'NEED_SVCGSSD=""' by default.

Problem solved. Thank you!

Hopefully these mailing list archives will help someone in the future.
