I get the following error on a Linux NLS server when trying to administer
Exception reading printer control
com.novell.service.iPrint.iPrintException: java.io.IOException

The error occurs when accessing the Printer Control leaf.
The strange thing is that some users, with the same rights, can access the
Printer Control leaf on the same servers iManager accessing the same
printer. It looks like it is user related but I cannot figure out where it
Users with this error get it on every single printer.
