IPP Authentication Mechanisms

IPP is layered on top of HTTP. As a result, the protocol uses the authentication mechanisms that are built into HTTP and the Apache software. The default configuration that is shipped in the Solaris OS doesn't make use of these authentication mechanisms in some releases of Solaris 9, Solaris 10, as well as the Solaris Express release. In the Solaris Express release, client authentication is required to access some uri-path and operation combinations.

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
