[Chris Coleman]

Package: samba4
Version: 4.0.0~beta2+dfsg1-1
Severity: normal

Dear Maintainer,

On installing samba4 I have encountered the above (shown below in more detail
when starting samba, in my smb.conf I have: 

   passdb backend = samba4

Error:

[2012/07/03 21:08:51,  0] smbd/server.c:1051(main)

I also recieve this error on starting the server:

root at server:~# /etc/init.d/samba4 restart
[ ok ] Stopping Samba 4 daemon: samba.
[....] Starting Samba 4 daemon: samba/usr/sbin/samba: /usr/lib/arm-linux-gnueabi/libwbclient.so.0: no version information available (required by /usr/lib/arm-linux-gnueabi/samba/libauth4.so)
.. ok

I initially tried an upgrade from samba3, however ultimately just provisioned 
samba with the following command: 

/usr/share/samba/setup/provision \
   --realm=karumbo.local.com --domain=KARUMBO \
   --adminpass=SOMEPASSWORD --server-role=dc

Which completed succesfully and created a bare bones smb.conf below:

# Global parameters
[global]
        server role = active directory domain controller
        workgroup = KARUMBO
        realm = karumbo.local
        netbios name = SERVER
        passdb backend = samba4

[netlogon]
        path = /var/lib/samba/sysvol/karumbo.local/scripts
        read only = No

[sysvol]
        path = /var/lib/samba/sysvol
        read only = No
