[Samba] rpcclient enumdrivers "result was WERR_UNKNOWN_PRINTER_DRIVER"

[Guido Lorenzutti]

Hi people!
I have a problem when I do a:

rpcclient -c "enumdrivers 3" -U glorenzutti beruti-cups

I get a:

result was WERR_UNKNOWN_PRINTER_DRIVER

This is my testparm output:

[global]
        unix charset = 850
        workgroup = SARASA
        netbios name = CUPS
        security = DOMAIN

        lprm command =

[printers]
        comment = All Printers
        path = /var/spool/samba
        printable = Yes
        browseable = No

[print$]
        comment = Printer Drivers
        path = /var/lib/samba/printers
        write list = @cupsadmin
        read only = No
        browseable = No

And I add a dump from the connection...

Any help would be great.

Tnxs in advance.
