The problem with mounting was my fault: I only installed 'linux-image' and
not 'linux-image-extra' which contains rpcsec_gss_krb5.ko. That module is
needed for mounting with 'sec=krb5'.
$ uname -r
3.8.0-030800rc5-generic
$ chgrp -v groupname newfile
chgrp: changing group of `newfile': Invalid argument
failed to change group of `newfile' from groupname to groupname
$ chown -v username newfile
chown: changing ownership of `newfile': Invalid argument
failed to change ownership of `newfile' from username to username
