[Samba] Can' t delete printjobs spooled in cups

[Andreas Grabner]

Hi,
i learned a lot about cups, samba and printerdrivers the last few days
and hours. I found a lot of mistakes but i can't change the following
situation:

I CAN NOT delete printjobs!
I can connect to the printers, automatic download the driver, print,
stop the printer, start the printer. 
Any tips, links, hints would be nice. 

My setup: Debian Sarge - Samba 3.0.14a - Cups 1.1.23. nss_ldap
Server role: ROLE_DOMAIN_MEMBER

The log says: 
[2005/10/04 14:53:08, 0] printing/print_cups.c:cups_job_delete(339)
  Unable to cancel job 8721 - client-error-not-authorized
