Hi,

i'm just testing a kerberized NFSv4 export of a ZFS-Filesystem. Both
client and server are FreeBSD at the moment. I tried Linux clients, but
could not mount with sec=krb5. If i mount an exported directory with
-o sec=krb5(i|p)i, directory listings with ls do sometimes take a very
long time (about 20times). Example output below.

> time ls -la
total 8
drwxr-xr-x+ 3 root    wheel     4 Aug 16 13:27 .
drwxr-xr-x  3 locadm  locadm  512 Aug 22 23:46 ..
drwxr-xr-x+ 2 root    wheel     2 Aug 16 13:27 testdir
-rw-r--r--  1 root    wheel     0 Aug 16 13:27 testfile
0.003u 0.003s 0:00.23 0.0%      0+0k 0+0io 0pf+0w
> time ls -la
total 8
drwxr-xr-x+ 3 root    wheel     4 Aug 16 13:27 .
drwxr-xr-x  3 locadm  locadm  512 Aug 22 23:46 ..
drwxr-xr-x+ 2 root    wheel     2 Aug 16 13:27 testdir
-rw-r--r--  1 root    wheel     0 Aug 16 13:27 testfile
0.000u 0.007s 0:04.27 0.0%      0+0k 0+0io 0pf+0w

The share is mounted by a local user with a kerberos ticket by 
mount -t nfs -o nfsv4,sec=krb5 130.149.58.249:/home mount.
Mounting with sec=sys does not produce this problem.
Has anyone experienced similar issues ?

cherio,
Leon
