running Netware 6.5 with Imanager 2.6SP2 and IPront Plugin 2.05.200606261

I am able to create Printer Driver Profiles on a W2K Workstation.
When trying to create a profile on XP i'm getting thios error after selecting the Manager and pressing OK:

Error: Create Printer Driver Profile Failure
Currently no drivers are stored in i-print-broker.inform-ac.com for this desktop operating system.

In fact, there are no XP Drivers, because the W2K drivers are the same ( in mostly all cases )
Netware doesn't deliver any XP drivers, because there's no need.

Is this behaviour by design ? ( one has to add all drivers for XP manually )
