More  informations about our problem: 

I've made some test from the binary package, using pkg_add -v samba, by following the instruction here: http://community
.qnx.com/sf/wiki/do/viewPage/projects.pkgsrc/wiki/BinaryPackages

I'm using *almost* the stock smbd.conf from the package.. I just specify the name of the workgroup and stuf like this.. 
I'm using the [home] share.. I've create a user with smbpasswd that exist on my system.

If I start smbd myself with -i, it will work for one connection no problem.. once the client exit.. the smbd process 
quit normally. But if I start it using: /etc/rc.d/smbd start  (started in Daemon mode).. It listen for connection but 
the client cannot connect.. 

The difference.. in Daemon mode.. there's more than one smbd process running and we got the following error in the log: 


[2009/01/10 11:30:50, 0] lib/util_tdb.c:tdb_log(664)
  tdb(/var/db/samba/ntforms.tdb): tdb_reopen: open failed (Resource busy)

It's seems that there's a problem of file locking with those tdb files.. when more than one smbd process open try to 
open them...

I've attached a more complete log... (with -d6 switch)
I know.. it's very verbose.. but the interesting stuff is at the end... 

Hope this will give a better idea of what is our problem..

conf. In the past, if I would connect to the QNX box using an XP computer that has a username and password that did not 
match the information in smbpasswd, the windows boxwill provide a prompt to enter a username and password for the 
connection. Now, samba quits on the QNX box.

Oooh my first bug report :)

I'll try to take a look at it in the near future.  It's been
a while since I've actually used samba so I may have a few
questions.
