SRA Overview | 23
Portals Overview
The SRA appliance provides a mechanism called Virtual Office, which is a Web-based portal
interface that provides clients with easy access to internal resources in your organization.
Components such as NetExtender, Secure Virtual Assist, and bookmarks to file shares and
other network resources are presented to users through the Virtual Office portal. For
organizations with multiple user types, the SRA appliance allows for multiple customized
portals, each with its own set of shared resource bookmarks. Portals also allow for individual
domain and security certificates on a per-portal basis. The components in a portal are
customized when adding a portal.
File Shares
File shares provide remote users with a secure Web interface to Microsoft File Shares using
the CIFS (Common Internet File System) or SMB (Server Message Block) protocols. Using
a Web interface similar in style to Microsoft’s familiar Network Neighborhood or My Network
Places, File Shares allow users with appropriate permissions to browse network shares,
rename, delete, retrieve, and upload files, and to create bookmarks for later recall. File
shares can be configured to allow restricted server path access.
Custom Portals
SRA appliances let you configure multiple portals, each with its own title, banner, login
message, logo and set of available resources. Each portal also enables you to set individual
Virtual Hosts/Domain Names to create a unique default portal URL. When a user logs into
a portal, he or she sees a set of pre-configured links and bookmarks that are specific to that
portal. You can configure whether or not NetExtender is displayed on a Virtual Office portal,
and if you want NetExtender to automatically launch when users log in to the portal. The
administrator configures which elements each portal displays through the
Portal Settings
window. For information on configuring portals, refer to the “Portals > Portals” section on
page 129 .
Domains Overview
A domain in the SRA environment is a mechanism that enables authentication of users
attempting to access the network being serviced by the SRA appliance. Domain types include
the SRA internal LocalDomain, and the external platforms Microsoft Active Directory, NT
Authentication, LDAP, and RADIUS. Often, only one domain will suffice to provide authentication
to your organization, although a larger organization may require distributed domains to handle
multiple nodes or collections of users attempting to access applications through the portal. For
information about configuring domains, refer to the
“Portals > Domains” section on page 148 .
Application Offloading and HTTP(S) Bookmarks Overview
SRA appliances use HTTP(S) bookmarks and application offloading to provide access to Web-
based applications running on servers within the intranet. This includes Sharepoint 2007 and
the enhanced versions of commonly-used Web mail interfaces, such as Microsoft OWA
Premium and Domino Web Access 8.0.1, 8.5.1, and 8.5.2. Sharepoint 2010 is supported with
application offloading, but not with HTTP(S) bookmarks.
