Samba no longer working - caused by update?

[Another Monkey]

I think an update or something has killed Samba on my Karmic box. it can see Windows shares OK, but it no longer appears on the Windows network. I have not changed my smb.conf for months, so something else has been modified.

Looking in the logs I can see the following in "log.winbindd-idmap" after restarting Samba

This is my smb.conf, as I say I have not changed it in months

	server string = Linux %h
#   wins support = no
	dns proxy = no

	pam password change = yes
	map to guest = bad user
	smb ports = 139

	usershare allow guests = yes

All other networking seems fine (internet, Synergy+ etc) it's just sharing out to the Windows network that is broken.

I've been searching but can't find an answer - anyone any idea what this problem is and how to fix it? Thanks.

Just noticed something odd. When I navigate to "Linux-Massive" in Nautilus, it jumps straight to showing me the shares from another PC (a Windows virtual image running on the Ubuntu host) rather than listing the PCs in the workgroup.

In Samba I just tried changing the workgroup name from "linux-massive" to "linux-test" and rebooting. I can see that workgroup but it is not accessible from Nautilus.

I'm pretty sure something is goosed in Samba/winbind; but I don't fell I know enough tech detail to log a bug.

I am also seeing this in log.winbindd-idmap

Weird. It seems to be working after the updates today (I was tired, I really didn't pay attention to what went in).
But with now changes, restarts or anything I can now browse to my Ubunut box from Windows.

I guess I will file this under PEBKAC.

I had the same problem. To fix it, make sure the following lines are NOT commented out:

   idmap uid = 10000-20000
   idmap gid = 10000-20000
