Problem with OpenSSH

[Antoine MILLET <antoine.millet@staff.epita.fr>]

Actually I'm using FreeBSD 5.5 under 1000 computers (EPITA / EPITECH, 
French Computer School).

Before July we ran NetBSD / NFS and now we've moved to FreeBSD / AFS.

I've a problem with OpenSSH / Heimdal / Arla

- GDM run perfectily with my krb5.conf, and I get kerberos ticket and 
afs tokens (I had an "afslog" in GDM's Xsession script).
- KINIT work perfectly with my krb5.conf, and I get kerberos ticket and 
afs tokens without any problem by running `kinit USERNAME`
*but*
OpenSSH don't log users without a keytab containing the host 
principal... Without this keytab I can log on the host.
I configure OpenSSH 4.6 with : ./configure --prefix=/usr 
--sysconfdir=/etc/ssh --with-ssl-engine --with-pam 
--with-kerberos5=/usr/local/heimdal
I configure Heimdal 0.8 with : ./configure --prefix=/usr/local/heimdal 
--sysconfdir=/etc/heimdal --without-ipv6 --with-x
I configure Arla 0.43 with : ./configure --prefix=/usr/local/arla 
--sysconfdir=/etc/arla --with-x --with-sys=/usr/src/sys 
--with-krb5=/usr/local/heimdal 
--with-krb5-include=/usr/local/heimdal/include 
--with-krb5-lib=/usr/local/heimdal/lib

I can't find a good solution... Normally Kerberos is one login and after 
use ticket, but acutally I ned one keytab and mutiple login...

Does anybody have an idee about that ?

Thanks in advance.
