How can a mount a NFS share exported from OpenBSD?

Hello Apple Discussions:

I've been experimenting with NFS in a mixed OS environment, and have been successful exporting nfs share with tigerserver, and mounting it on both a powerpc linux system, and on a powerpc openBSD system.

Likewise, I can export a NFS share from the linux powerpc box, and mount it on the openBSD box and on the tigerserver, although, the latter required using the options (ro,sync,insecure) in my exports file.

However, when I export a share on the OpenBSD box, I can mount it on the linux box, but not on tigerserver.

I would like for the OpenBSD box to export a NFS share securely, with read-write permissions, to the tigerserver.

After reading so many tutorials, that it would be a page of links, just to list them all, I am pulling my hair out. However, I have found one thread that suggests, that perhaps what I'm trying to do is impossible:

http://www.bsdforums.org/forums/showthread.php?t=54308

Here it is suggested that the NFS won't work because tigerserver is not using UTF-8?

I will have to say, that I was somewhat alarmed, that the only times I succeeded in mounting an nfs share exported from linux onto tigerserver, it was when the "insecure" option is used in the /etc/exports file. There doesn't seem to be an equivalent for the linux style exports option "insecure", in the bsd style options of --maproot=user:group1:group2.

But I don't like using any options that say "insecure" anyways, so rather than trying to find out how to make openbsd "insecure", I would rather like to find out if there is a way to get tigerserver using UTF-8, at least when mounting NFS shares, if this is indeed the issue.

Here are the more technical details. I've created a user on all sytems named "fives" with the userid of 5555 and the groupid of 5555. I made the user local user in the local net info domain, but I've tried it with an LDAP user as well. The folders I wish to export and the folders into which to mount them are all owned by user fives and group fives, and have permissions set to 0775. The ip addresses are OpenBSD=192.168.222.111 TigerServer=192.168.222.233 LinuxPPC=192.168.222.253. I've included the relevant NFS setup files and running processes below:

ON THE OPENBSD BOX:

#/etc/exports
/fives -alldirs -network=192.168.222.0 -mask=255.255.255.0
/exports/fives -mapall=fives:fives 192.168.222.233 192.168.222.253

#/etc/hosts.deny
ALL: ALL

#/etc/hosts.allow
ALL: 192.168.222.233 192.168.222.253

#/etc/rc.conf.local
portmap=YES
lockd=YES
nfs_server=YES

#here's proof that the daemons are running on the OpenBSD box;
rpcinfo -p localhost
program vers proto port
100000 2 tcp 111 portmapper
100000 2 udp 111 portmapper
100005 1 udp 863 mountd
100005 3 udp 863 mountd
100005 1 tcp 613 mountd
100005 3 tcp 613 mountd
100003 2 udp 2049 nfs
100003 3 udp 2049 nfs

100003 3 tcp 2049 nfs
100021 1 udp 895 nlockmgr
100021 3 udp 895 nlockmgr
100021 1 tcp 706 nlockmgr
100021 3 tcp 706 nlockmgr
# actually, I don't see statd, but haven't found the equivalent in openbsd. There's rpc.rstatd, and maybe it should be listed here, but there doesn't seem to be a way to launch it directly. This is a competitor with the UTF-8 theory about why it's not working.

ON THE TIGER SERVER:
# here's proof that tiger server sees the mounts:
showmount -e 192.168.222.111
Exports list on 192.168.222.111:
/fives 192.168.222.0
/exports/fives 192.168.222.233 192.168.222.253

# here's the result of user fives' attempt at mounting a share:
sudo mount -t nfs 192.168.222.111:/exports/fives /imports/fives
mount_nfs: /imports/fives: Permission denied

# yet user fives has no problem mounting same share on linuxppc box.

What is different about OSX server? I thought it was supposed to speak NFS?

---argh... I'm steppin out for a pint.. Hopefully when I'm back it'll just work.
