[Samba] printer admin deprecated: please explain

[Franz Pfoertsch]

I am Running a printserver using SLES9 SP3 with Samba 3.0.20b and 
cups 1.1.20 
Since the update to Samba 3.0.20 every start of a client program tells me
WARNING: The "printer admin" option is deprecated

Ok, I understood I should use 

 net rpc rights grant "<User or Group>" SePrintOperatorPrivilege -U ..

But I haven't any adminuser to grant this rights.

In my environment I put the machine into the AD by
 kinit <UserWithPermissionsToJoinIntoTheDomain>@<DOMAIN>
 net ads join -> joined

and all permission granted by the "printer admin" option.

Is there any other way to get SePrintOperator without a other strong user?

regards
Franz
