Version Control Installation Guide

All connections and data are transferred using Secure Sockets Layer (SSL) communications over HTTP.
Interactive users connect using a web browser (client) application. The specific security depends on which
web application they are browsing.
HP SIM uses operating systems authentication, based on the server where it is installed. Single sign-on
enables a user that browses to the HP SIM system to follow links from that system to other managed systems
without being prompted to login again.
When the same user browses directly to a managed server, they must authenticate through the SMH, using
an account and password that is valid on that system.
HP SIM communicates with web applications, such as the VCA and the VCRM, using Secure Task Execution,
which is enabled by configuring the SMH to trust that central management server (CMS). Refer to the System
Management Homepage Installation Guide for information regarding configuring the SMH.
Finally, when the VCA communicates with a VCRM, it acts as a client application, and requires the same
kind of authentication information, such as an account and password, that an interactive user needs to login
to the SMH on which the VCRM is installed. The SMH requires a valid operating system account and
password. Refer to the VCA online help for more information regarding configuring these settings for the
VCA.
For more information regarding the SMH, refer to the System Management Homepage Installation Guide .
