I sent your smb.conf through "testparm" to get a file that's cleaned
out from all settings that are default values.

The result is attached to this mail. I just commented the two lines
with "interfaces" and "bind interfaces only" that only fit your local
setup.

Then I started samba with this and tried connecting to my home
directory (after "smbpasswd bubulle"):

bubulle at mykerinos:~/src/debian/cipux-cat-web/debian> smbclient //127.0.0.1/bubulle -U bubulle
Enter bubulle's password:
Domain=[THETAPHI] OS=[Unix] Server=[Samba 3.2.1]
Server not using user level security and no password supplied.
Server requested LANMAN password (share-level security) but 'client lanman auth' is disabled
tree connect failed: SUCCESS - 0
bubulle at mykerinos:~/src/debian/cipux-cat-web/debian>

OK....I need to activate "cllent lanman auth". This is a known change
in 3.2....So, I add this to smb.conf:

        client lanman auth = Yes


Restarting samba and:

bubulle at mykerinos:~/src/debian/cipux-cat-web/debian> smbclient //127.0.0.1/bubulle -U bubulle
Enter bubulle's password:
Domain=[THETAPHI] OS=[Unix] Server=[Samba 3.2.1]
Server not using user level security and no password supplied.
.../... (20 seconds)
Receiving SMB: Server stopped responding
tree connect failed: Call timed out: server did not respond after 20000 milliseconds
bubulle at mykerinos:~/src/debian/cipux-cat-web/debian>

Now, stopping samba indeed leaves two smbd processes....



Is this the behaviour you get ?

If I change from "security = share" to "security = user", things work
as expected.
