samba - Dec 2003 - Samba 3.0.0, CUPS support - "Unable to open printcap file cups for read!"

Hello,

I've compiled Samba 3.0.0 with CUPS support.  I verified this:

# ldd /usr/local/samba/sbin/smbd
 *snip*
 libcups.so.2 => /usr/lib/libcups.so.2 (0x400dc000)     
 *snip*

My smb.conf was copied from the HOWTO and the relevant sections look
like:

[global]

 *snip*

  # print support
  load printers = yes
  printing = cups
  printcap name = cups
  
*snip*

[printers]
  comment = All Printers
  path = /var/spool/samba
  browseable = no
  public = yes
  guest ok = yes
  writable = no
  printable = yes
  printer admin = root, @ntadmins


I log into the domain on an XP Pro client using the root account, and if
I try to browse to the printer via My Computer --> My Network Places -->
Entire Network --> MyDomain --> ds119b (this is my samba server) -->
Printers and Faxes, it comes up blank.  If I try to directly access the
printer via \\ds119b\MyPrinterName, it gets stuck in a loop.  In both
cases, I am getting errors like this:

Dec  9 13:38:17 ds119b smbd[21244]: [2003/12/09 13:38:17,
0] printing/pcap.c:pcap_printername_ok(282)
Dec  9 13:38:17 ds119b smbd[21244]:   Unable to open printcap file cups
for read!

Any ideas?  Thanks!

-Fran

A couple more data points:

# smbclient //ds119b/ps4
Password:
tree connect failed: NT_STATUS_BAD_NETWORK_NAME
# 

The syslog shows this as a result:

Dec  9 13:46:47 ds119b smbd[21284]: [2003/12/09 13:46:47,
0] printing/pcap.c:pcap_printername_ok(282)
Dec  9 13:46:47 ds119b smbd[21284]:   Unable to open printcap file cups
for read!
Dec  9 13:46:47 ds119b smbd[21284]: [2003/12/09 13:46:47, 0]
smbd/service.c:make_connection(850)
Dec  9 13:46:47 ds119b smbd[21284]:   ds119b (192.168.2.232) couldn't
find service ps4

I can successfully print to this printer from the samba linux host via
the standard lpr -Pps4 approach.  I checked my cupsd.conf to make sure
it had a Printcap = /etc/printcap and PrintcapFormat = BSD entries and
it does.  The generated /etc/printcap has only one non-comment line,
"ps4:".

It means Samba doesn't know about a printer share named "ps4"
(nor a file share of that name)....

This message might be bogus in your context and not lead to
your real problem...

Have you also checked your smb.conf for an entry of

    "load printers = yes"

??

That's OK.

Hopefully a dumb question... but is cups running?  Also, what does an
lpstat -a show?
