Status rc means: removed, config left.

I've been using Samba4 on Debian/Jessie since it became "stable". After the
last upgrade however, I got a massive failure.

Thanks. Noticing the versions mismatch, I (re)installed winbind and it 
grabbed the current version. Restarting fixed everything.

  Numeric stability is probably not all that
  important when you're guessing;-)

samba4 stopped working

[Gary Dale]

I've been using Samba4 on Debian/Jessie since it became "stable". After 
the last upgrade however, I got a massive failure.


The first symptom I noticed was that I couldn't grab updates from the 
Debian servers. However when clients tried to log in, the real problem 
revealed itself. They could only log on using a temporary profile and 
couldn't connect to any of the shares or printers.


When I test my implementation of Samba, it fails the basic test:

# smbclient -L localhost -U%
Connection to localhost failed (Error NT_STATUS_CONNECTION_REFUSED)

The globals section of smb.conf is:

[global]
workgroup = DENTALOFFICE
realm = DENTALOFFICE.ROSSLAND.DENTAL
netbios name = MOLAR
server role = active directory domain controller
dns forwarder = 8.8.8.8
idmap_ldb:use rfc2307 = yes
allow dns updates = nonsecure

which explains why I can't get to the Debian servers. The hand off to 
Google's DNS servers never happens.


ps aux | grep  nmbd, smbd or samba all show that samba isn't running. 
The logs for starting samba show:

Although the message about the daemon being ready seems to indicate that 
samba is running, as I said, ps aux shows that it isn't.


Any ideas how I can get Samba back up? Uninstalling and reinstalling it 
didn't work.
