kerberos nfs4's principals and root access
Hai Batiste,
Ok, thanks for these, i'll test that also.
And the "why" is a bit more explained here.
http://www.citi.umich.edu/projects/nfsv4/crossrealm/libnfsidmap_config.html
and per example,
http://www.citi.umich.edu/projects/nfsv4/crossrealm/ldap_server_setup.html
First my work here, but this is a good one which i also need to adjust in my scripts, so thank you for asking

Here you go..
But all my settings are scripted.
https://github.com/thctlo/samba4

Read the script : samba-with-nfsv4.sh
Start it like ./ samba-with-nfsv4.sh (client or server)
Its tested and works on debian jessie.
I contains the nfs server settings and client settings.

kerberos nfs4's principals and root access
Hi,
Sorry for this necrobump.... But I'm still can't use my local root
user to browse content of my NFSv4/Krb5 share...... (others permission
are checked when root use this share)
So a lot of questions appeared during my tests :
- Must i have same idmap.conf on both client and server ?
- Why rpc.idmapd only use 'nsswitch' method even if 'static' is

FW: kerberos nfs4's principals and root access
If not done, add the server to the AD.
Add the host and nfs to the COMPUTERNAME($) account.
And use winbind to refresh the keytab.
Stop samba,
remove the keytab, create the new with the new SPN's in it,
start samba.
And Use the second keytab for apache with only http as upn in it.

Read : http://linux.die.net/man/5/idmapd.conf
Working on it now.

kerberos nfs4's principals and root access
Thanks you very much Louis !
I have tried your setup and I can't mount the share neither from the
server itself or the client.
On /var/log/syslog I have :
rpc.gssd : ERROR : no credentials found for connecting to server myserver
This is because the machine principal is not present in the keytab :
$ klist -k
1 nfs/myclient.samdom.com at SAMDOM.COM
1 nfs/myclient.samdom.com at SAMDOM.COM

FW: kerberos nfs4's principals and root access
Ah ok, you are using "public_html" from a default setup.
Now i understand what you exact want.
If you have the apache keytab created.
Create a cron job and run :
kinit -t /path/to/keytab as the www user.
Dont forget het disable the password change in the AD user for
the "apache Service user" account.
You probely also need to export some kerberos variables like :

kerberos nfs4's principals and root access
Hai Baptiste,
I re-checked my setup and your totaly correct.
I can not enter the nfsV4 mounted directory as root.
What i've added in idmap.conf
Is this :
Domain = your_DNS_domain.tld
[Translation]
Method = nsswitch
And i found this link.
http://serverfault.com/questions/526762/root-access-to-kerberized-nfsv4-host-on-ubuntu
im testing this now.

kerberos nfs4's principals and root access
Hai,
I had it the other way around. Only root acces.
I have scripted my setup and tested on debian.
Look here
https://secure.bazuin.nl/scripts/these_are_experimental_scripts/
setup-nfsv4-kerberos.sh
If you get the file, setup-nfsv4-kerberos.sh and compair it to your setup.
If you can read the bash script maybe you see something you missed.
When i write as "root" its root and

FW: kerberos nfs4's principals and root access
It's ok
So, if I create a httpuser and an httpgroup in my AD and use these at
owner and group for my apache2 daemon, this one could access to userdirs
(while permissions granting it) ? But I need to cron 'kinit' to keep
valid ticket... ?
My local root user always can't access to the share, but my other
problem seems to be resolved.
Thanks

You need for the apache keytab something like
Alias /webmail /usr/share/webmail
#
<Directory /usr/share/ webmail >
AuthType Kerberos
AuthName "Kerberos Login"
KrbMethodNegotiate On
KrbMethodK5Passwd Off
KrbServiceName HTTP
KrbAuthRealms EXAMPLE.COM
Krb5KeyTab /etc/httpd/conf/keytab
require valid-user
</Directory>
chmod 400 /etc/httpd/conf/keytab
chown

FW: kerberos nfs4's principals and root access
Hi Rowland,
I've already read this article, but I never find how to indicate to
apache to read this file... After some research, I think I need to
install mod_auth_krb5 to specify at least how to find this keytab (even
if I don't need Apache authentication against Kerberos).
I will try this today and comme back to say if it works !
In fact i'm stuck between my two problems (root

NFSv4 + Kerberos understanding
Hi,
I've a SAMBA4 AD Domain that works nicely. All my W7 joined perfectly
and all my Linux clients authenticates against kerberos part of SAMBA.
All work perfectly, now I'm trying to secure my NFS mounts by using
kerberos part of SAMBA.
My NFS server works and I can mount NFS4 exports without kerberos (and
without problem ;-) ), but when I want to mount a gss/krb5 export on a

kerberos nfs4's principals and root access
Hello samba team !
I have some NFS4 exports managed by a Samba's Kerberos realm. All the
standard user accesses work fine.
I try now to setup an NFS4 root access to administer the share from
another server (the two host are DC, one PDC and one SDC). But I have
trouble understanding the kerberos/principals layer.

Actually I do

Winbind/AD/NFSv4: can't `ls/cd` private directory?
Hello everyone,
We have a CentOS 6.3 NFSv4 server and client, and we've run into a situation where the client is unable to list "private" (chmod 700-ed) directories, even if the current user owns the directory in question.
A bit more background: we're also using Samba 3.5+Winbind to provide authentication and UID/GID mapping against a Windows 2008 R2 domain controller.
