[Samba] Unable to enable Add/Remove Printer Drivers (3.0.0)

[Adam Williams]

I used to be able to load printer drivers via "server properties".  Now
when I go in the printer drivers are listed and I can use the properties
button but the Add/Remove buttons are greyed out.  This is a Samba
3.0.0/2.4.2-SGI_XFS_1.0 box and I've tried both NT4sp6 and Win2003beta
clients (both exhibit the same behaviour).

I see the following in the log when I connect to "\\barbel\Printers and
Faxes"

My [print$] looks like -
[print$]
        path = /usr/local/pcnet/printers
        guest ok = yes
        browseable = yes
        read only = no
        create mask = 0644
        directory mask = 0755
        force user = pcnet
        force group = cis

And I've set all the permissions wide open to try and get this to work.

"net rpc user info adam -S littleboy -U adam" shows my user as a member
of the "Print Operators" group, which my potentially flawed
understanding I though gave me Print Administrative rights.
