ETV Portal Server Admin Guide 71
† ETV Portal Server required field. All others are optional.
Single Sign-On
To use single sign-on, go to Access Control and then check Enable Authentication and
Authorization
and Use LDAP Database. If the LDAP server is Microsoft Active Directory,
you can select Use Integrated Windows Authentication to enable "MCS Single Sign-on."
This means that once you login to your local network with your assigned credentials, you can
open ETV Portal Server without re-entering your login credentials. ETV Portal Server uses
your assigned credentials to authenticate and authorize your defined permissions within the
application. (If using an LDAP directory other than Microsoft's Active Directory, VBrick
strongly recommends using SSL to encrypt the communication between the Portal Server
server and the LDAP directory. Please consult your LDAP vendor documentation for
instructions on how to configure SSL.) When configuring for Integrated Windows
Authentication, keep the following points in mind:
• Integrated Windows Authentication is only valid when using LDAP Authentication with
Microsoft Active Directory.
• You must perform an additional configuration step in IIS as explained below in
Configuring IIS for Single Sign-On
.
• Integrated Windows Authentication only works seamlessly with Microsoft Internet
Explorer browsers (Windows and Macintosh). When accessing ETV Portal Server, you
will get a popup login window only if you have not previously logged in to the network.
• When using Integrated Windows Authentication, all single-sign-on users must have an
Active Directory account and the Portal Server must be part of the Windows domain.
• When using Integrated Windows Authentication, Microsoft Internet Explorer's default
behavior is that it will not prompt for an ID/password when the server is in the
Local
Intranet Zone
. (By default, Internet Explorer assumes a URL without a period (.). This
