Having trouble with samba printing. I have a CUPS printer installed on an Ubuntu 11.04 server and that works great.

When I try to configure samba to allow an XP machine to use the printer, it fails when printing. I can install the printer drivers for XP from the server and the printer appears in the XP printer control panels. When I try to print a test page from the XP machine I get this error in the system event log:

Jun 27 20:33:29 FatController smbd[3571]: [2012/06/27 20:33:29,  0] rpc_server/srv_netlog_nt.c:603(_netr_ServerAuthenticate3)
Jun 27 20:33:29 FatController smbd[3571]:   _netr_ServerAuthenticate3: netlogon_creds_server_check failed. Rejecting auth request from client JAMES machine account JAMES$

Here's my smb.conf file:

[global]
server string = %h (Server)
workgroup = SODOR
encrypt passwords = true
security = user
os level = 255
preferred master = yes
domain master = yes
local master = yes
logon path = \\%L\profile\%U
logon drive = S:
logon home = \\%L\home\%U
domain logons = yes
map to guest = Never
guest ok = no
dns proxy = no
time server = yes
logon script = logon.bat
load printers = yes
printing = cups
printcap name = cups
nt acl support = no

smb ports = 445

[netlogon]
comment = Net Log On
path = /home/samba/netlogon
guest ok = no
read only = yes
browseable = no

[profile]
comment = User Profiles
path = /home/samba/profiles
read only = no
create mask = 0600
directory mask = 0700
browseable = no
store dos attributes = yes

[printers]
comment = All Printers
path = /var/spool/samba
browseable = yes
guest ok = no
printable = yes

[print$]
comment = Printer Drivers
path = /var/lib/samba/printers
browseable = yes
guest ok = no
read only = yes
write list = root, skizz

Anyone know what the problem is and how to fix it?

In addition to the above, I also get this error:

Jun 27 21:56:35 FatController smbd[3571]: [2012/06/27 21:56:35,  0] printing/print_cups.c:1027(cups_job_submit)
Jun 27 21:56:35 FatController smbd[3571]:   Unable to print file to `Edward' - client-error-not-authorized

which I think is more relevant.
