[Samba] Problem with stale smdb processes when users log out

[Peter Loron]

I'm running Samba 3.0.0-15 (default install) on a Fedora FC1 machine. 
I've attached the smb.conf file below. The Samba server is acting as a 
WINS server on our testlab network, but is not a PDC, nor is it joined 
into a domain. Users authenticate by using a username/password that is 
local to the Samba server.

The problem I'm seeing is that when a user has been connected to the 
Samba server and then logs out of their Windows machine, the connections 
sometimes persist. As an example:

1. User logs in to a WinXP or Win2K3 machine using a domain account (the 
domain PDC is another Windows machine, not the Samba machine).

2. Once in Windows, a connection to the Samba machine is opened via the 
Run menu (\\server\share). The connections ('IPC$' and 'sharename' can 
be seen via smbstatus and 'net use').

3. User logs out of the Windows machine without explicitly disconnecting 
from the Samba server.

4. Connections on the Samba server can sill be seen with smbstatus.

4. User logs in to the same Windows machine, this time with a local 
machine account (such as localMachine\Administrator).

5. User tries to connect to the Samba server using the Run menu, and 
gets an error saying that the password is invalid. Checking with 'net 
use' shows that a connection to the Samba server already exists.

6. Deleting the connection ('net use \\server\share /delete') sometimes 
restores functionality, but not consistently.

Any ideas? Thanks.
