Select a specific Virtual Host Interface for this portal if using IP based virtual hosting.
Step 5
If your virtual host implementation uses name based virtual hosts — where more than one
hostname resides behind a single IP address — choose All Interfaces from the Virtual Host
interface.
If you selected a specific Virtual Host Interface for this portal, enter the desired Virtual Host IP
Step 6
Address in the field provided. This is the IP address users will access in order to access the
Virtual Office portal.
Note
If you selected a specific Virtual Host Interface for this portal, you can specify an IPv6 address
Step 7
in the Virtual Host IPv6 Address field. You can use this address to access the virtual host.
Enter the IPv6 address using decimal or hexadecimal numbers in the form:
If you plan to use a unique security certificate for this sub-domain, select the corresponding port
Step 8
interface address from the Virtual Host Certificate list.
Unless you have a certificate for each virtual host domain name, or if you have purchased a
*.domain SSL certificate, your users may see a Certificate host name mismatch warning
when they log into the SRA appliance portal. The certificate hostname mismatch affects the
login page, NetExtender, and Secure Virtual Access/Assist/Meeting clients; Other SRA client
applications will not be affected by a hostname mismatch.
To achieve a single point of access for users, configure External Website Bookmarks for
application offloading portals by selecting the Enable Virtual Host Domain SSO check box to
enable cross domain Single Sign-On (SSO). Cross Domain SSO shares the credentials for all
portals in the same shared domain. Enabling Virtual Host Domain SSO automatically sets the
Shared Domain Name one level up from the Virtual Host Domain name and displays it in the
Shared Domain Name field. For example, the Shared Domain Name is example.com if the
Virtual Host Domain is webmail.example.com.

Be sure to add an entry in your external DNS server to resolve the virtual hostname
and domain name to the external IP address of your SRA appliance.

In previous releases, users had to log in twice – once for the regular portal and once
for the application offloading portal after External Website Bookmark redirection.
The Cross Domain SSO feature allows users after logging into the main portal to
automatically log into application offloading portals or Web sites that share the same
Virtual Host Domain.
