IPP Authentication Mechanisms

IPP is layered on top of HTTP. As a result, the protocol uses authentication mechanisms that are built into the HTTP and the Apache software. In certain Oracle Solaris releases, the default configuration that is shipped with the operating system does not make use of these authentication mechanisms.

For example, the more common form of printer-uri that is used by client systems is:

ipp://server/printers/queue

When printing on a system that is running a version Windows, specify the URI by using the following syntax:

http://server:631/printers/queue
