samba - Dec 2005 - "Unable to display security information" on windows printers security tab

Hello,

I just installed RHEL3 on a brand new server, with samba and cups. The
packages used are RHEL3 official RPMs samba-3.0.9-1.3E.5 and
cups-1.1.17-13.3.32.

I configured samba with security = ADS, and i can authenticate my
users on our windows domain AD; everything works fine with files and
shares, etc.

When i configure a cups printer, and then export it to samba, i can
add drivers  thru the windows interface into the [print$] share as a
printer administrator, connect to it, download and install drivers,
print a test page. it just works like a charm.

But... if i look in the printer properties window, i can't access the
security information of the printer. when i click on the security tab,
i get this message: "Unable to display security information".

If i try to connect and auto install the printer drivers from a normal
user account, i get this message: "Unable to connect. Access denied"

I also tried with SERNET samba3 rpm version 3.0.20b, same problem.

When browsing the archive of this list, i found a post describing the
same problem, and Gerald (Jerry) Carter asked for the ouput of this
command:

[root@medellin cups]# rpcclient medellin -U CCI_74+administrateur  -c
'getprinter X535-C3 3'

Does anyone know what cause this problem? Where should i look to
understand and hopefully fix this problem?
