iPrint error

I get the following error trying to create an iPrint printer:

Error: Create Printer Failure
Request (CLIENT_ERROR) - bad status code (0x400)
IPP Error: 0x400

The server is running these versions:
novell-iprint-iprntman-6.1.20090603.0.4.1
novell-iprint-server-6.1.20090608-0.4.1

I can't find anything related to this error message. Help!
