Bug 107836

The following has be reported by IBM LTC:  
Redhat-config-printer won't configure a samba printer
I exported my display and ran redhat-config-printer.  I tried to attach a 
Networked Windows (smb) printer.  I typed in the workgroup, my W2K desktop 
system, share, userid, and password and hit enter.   The window just comes 
right back with the same prompt.  I verified the printer was shared by using a 
W98 box with only netbeui installed (no tcp) and it worked ok.Khoa/Salina,

Sounds like this is possibly platform-independent. Can you work this one?
Thanks.Ok Olof,
I think our test team has a samba printer, will try to re-create on IA32 
sometime next week.  I don't have time this week.  Installed RHEL 3.0 RC4 AS on
Netvista box.
( This is Taroon-re1007.RC1.* )
I did not have any problem using redhat-config-printer to add a samba printer.  
The printer is IBM info print 20 on a Windows machine - I don't know what O/S 
is running on that Windows machine - will need to ask owner.
Adding the printer also printed off a test page correctly.
Olof, Khoa said to transfer problem back to you.
Your team has your own contacts with RedHat.
SalinaKhoa,

Please drive this problem to closure on your side, I'm sure Ray can assist you
if you need remote access to an iSeries system to reproduce. Feel free to open
up a mirror bug to RedHat using your own channels. Thanks.I thought you insisted
on using your own channel to communicate with the
distros.  Any reason why you wanted to change this ?Over to Thinh. Please mirror
this as a Service bug even though we work it.Ray,
Can you capture some network packet between these two boxes? or at least 
packets coming in/out from Linux system.  It wouls be great if using ethereal.

And what is the service pack on you Win2K?Conntacting Ray for more
information.The problem seem to be access being denied.
Printer Server:
 - level: Win2K SP4 (plus other hot fixes)
 - hostname: voyager
 - sharename: RAYDASCOLOR

RedHat Linux as client:
 - level: 2.4.21-3.EL #1 SMP Fri Sep 19 13:58:19 EDT 2003 ppc64
          samba-client-3.0.0-14.3E
 - hostname: ilinjck6

SMB protocols begin:
 - Negotiate Protocol request/response: server picked dialect 8
 - client sent Session Setup AndX request, NTLMSSP_NEGOTIATE
 - server response Setup AndX, NTLMSSP_CHALLENGE
 - client sent Setup AndX, NTLMSSP_AUTH with username/password
 - server response with failure, Error: STATUS_LOGON_FAILURE
 - client sent Setup_AndX with user: anonymous (NULL/NULL)
 - server response success
 - client sent TreeConnect_AndX request, Path:\\VOYAGER\RAYDASCOLOR
 - server responsed, Error: STATUS_ACCESS_DENIED
SMB protol ends.

still looking .....
I tried my Redhat (i386) as the client, and it works when mapping a printer to
the same server, \\VOYAGER\RAYDASCOLOR:
 - level: 2.4.20-18.9 #1 Thu May 29 07:08:16 EDT 2003 i386
 - samba client: samba-client-2.2.7a-8.9.0

this (samba) client level does normal SMB protocols transactions:
 - client sent negotiate request
 - server responsed negotiation response, pick index 7 (the highest)
 - client sent Session Setup_AndX with username/password
 - server responsed OK.
 - client sent TreeConnect_AndX, path: \\VOYAGER\RAYDASCOLOR
 - server responsed OK.

This is Samba issue. At this time, we know the samba client 3.0.xx is broken on
ppc64. We need verify:
 - Samba client 3.0.xx on i386
 - Samba client 2.2.xx on ppc64

Khoa, Do you have anyone in your team handle samba issues?
Yep, Samba 3.0xx is broken.
I installed samba-3.0.0-2_rh9.i386.rpm from samba.org on my Redhat i386, it also
failed.
OK, this is strange.
The smbclient 3.0.xx is working, I tested it by using command lines to map to
the printer share and it all worked:

   # smbclient -U thinh //voyager/RAYDASCOLOR  thinh1
or # smbclient //voyager/RAYDASCOLOR -U thinh thinh1
or # smbclient //voyager/RAYDASCOLOR -U thinh%thinh1
 
I compared the network packets between the bad (printer gui) case and the good
(command line) case, both are using the same protocols and autherntication
method, NTLMSSP, most information are identical, the one is in question is the
password.

I'm still trying find out what the differences in smbclient 3.x that makes this
doesnot work anymore. 

Found it. The problem is the smbclient version 3.0.x with -N option, it will
ignore the specified password and send a NULL password instead (I assummed) and
since server and client negotiated with LMTNv2, a higher autherntication method,
it requires a valid password. After this fails, smbclient send a NULL/NULL
Session Setup request, Win2K accepts the session but doesnot allow to map the
printer share. I'm not sure this '-N' option working the same way on version
2.0x or not.


Here the patch fixing this:

Ray, The patch is currently on this machine. Please verify it. thanks.

Look like this '-N' option issue is the same with RedHat bug#81173.

patches for redhat-config-printer-gui with smbclient v3.0.x
Glen, since this is a Service family bug, can you mirror it over? THanks.Added
the wrong email address for Glen.this should be backward compatible with
smbclient v2.xx with '-N' option for the
 smbprint:
