Samba 4 alpha 6

Samba 4 alpha 6

A quick view on Samba 4 alpha 6 (January 2009). You can also follow this guide

Remove old Samba from Red Hat

yum remove samba

set a fix ip address (Red Hat has an easy GUI)

download and untar, click 'download info', choose mirror, dl samba4 latest alpha

once untarred, enter the directory and read the howto4.txt

cd samba-4.0.0alpha6/
more howto4.txt

first we have to configure, compile and install samba4

cd source4/
make install

Then we can use the provision script to setup our realm. I used booi.schot as domain name (instead of

./setup/provision --realm=BOOI.SCHOT --domain=BOOI --adminpass=stargate \
--server-role='domain controller'

i added a simple share for testing

vi /usr/local/samba/etc/smb.conf

then i started samba

cd /usr/local/samba/sbin/

I tested with smbclient, it works

smbclient //localhost/test -Uadministrator%stargate

I checked that bind (and bind-chroot) were installed (yes), so copied the srv records

cp /var/named/chroot/etc/

then appended to named.conf

cat named.conf >> /var/named/chroot/etc/named.conf

I followed these steps in the howto4.txt

vi /etc/init.d/named  [added two export lines right after start()]
chmod a+r /usr/local/samba/private/dns.keytab 
cp krb5.conf /etc/
vi /var/named/chroot/etc/named.conf
	--> remove a lot, but keep allow-update { any; };

restart bind (named!), then tested dns with dig, this works (stripped screenshot!)

[root@RHEL52 private]# dig _ldap._tcp.dc._msdcs.booi.schot SRV @localhost

made sure /etc/resolv.conf points to himself

[root@RHEL52 private]# cat /etc/resolv.conf
search booi.schot

start windows 2003 server, enter the samba4 as DNS!

ping the domain, if it doesn't work, then add your redhats hostname and your realm to windows/system32/drivers/etc/hosts

join the windows computer to the domain

reboot the windows

log on with administrator stargate

start run dsa.msc to manage samba4

create an OU, a user and a GPO, test that it works
