Trying to install current samba4 svn version on a fedora core (6) system (2xXeon 2.4 ghz, 2gb ram).

Followed the included howto:

svn co svn://svnanon.samba.org/samba/branches/SAMBA_4_0 samba4
cd /usr/src/samba4/source
./autogen.sh
./configure --prefix=/usr/local/samba --enable-developer --enable-automatic-dependencies
make pch all
make install

Included /usr/local/samba/bin into the PATH

cd /usr/src/samba4/source
./setup/provision --domain=demo --realm=demo.local --adminpass=demo

I got the following error:

ERROR: Could not determine network interfaces, you must use a interfaces conf line
WARNING: no network interfaces found
set DOMAIN SID: S-1-5-21-3479567878-3861543463-2998501656
smbscript: ejsEvalScript(): Assertion failure

Backtrace: [ 0] provision_fix_subobj:9 -> assert(valid_netbios_name(sub.NETBIOSNAME))
[ 1]:133 -> provision_fix_subobj(subobj, paths)

When compiling the official released tar file (alpha1) there´s no error about "problems determing network interface" but the error concerning "valid_netbios_name" still remains.

I tried serveral different fc6 kernel environments (xen, non-xen) (kernel-xen-2.6.20.x, kernel-2.6.18.x, kernel-2.6.22.x)

Googled around but found no similiar reported problems.

Any help is appreceated.
Kinds regards
