[Samba] Point n Print, Printer Settings Could Not Be Saved

[eric]

Looking for some help on this. (like everyone else).
 
This appears to be a very well asked about problem and the advise is always
the same... Check permissions here and there.
 
My set up is:
 
OpenSLP 1.2.1
OpenLDAP 2.4.7
Samba 3.0.28
nss_ldap
CUPS 1.3.5
 
I've got everything working except the ability to add a "New Driver" from
Windows XP Pro.
 
Samba is running as a PDC / Domain Logins
 
I've ran strace on my smbd processes with no luck.
 
Short of sniffing network packets and digging into the source code, I'm
hoping this well traveled issue has some better support in this mailing
list?
 
Relevant parts of my smb.conf file are as follows:

## PRINTING Section Global Settings
        ; if you want your own defined print commands to work
        ; with a Samba that has CUPS support compiled in, simply use
printing = sysv
        printing = cups
        printcap name = cups
        ; note: the /etc/printcap was a work around to get the printer to
show up
        ; under windows.  I eventually was able to comment it out in favor
of the
        ; line above, printcap name = cups, after discovering that cupsd
only works
        ; with utf-8 character sets.  So I had to set the Linux OS locale to
EN_US.UTF8
        ; and after doing that, things started working!  This is not
documented very well
        ; if at all.  CUPS documentation talks about UTF8 dependency but it
does not talk
        ; about how it affects samba here nor do the samba documents mention
this.
