Integrate WebEx with Identity as a Service

Webex is a cloud-based collaborative video conferencing product suite (see https://webex.com/). You can protect access to Webex by integrating Webex with Identity as a Service. Once integrated, users can use single sign-on to log in to their WebEx account through Identity as a Service.

Note: This guide was tested using previous versions of Identity as a Service and Webex. Other versions of Webex may require integration and configuration steps that differ from those documented in this procedure. For newer versions of Webex, this integration guide may be used as an initial approach for integrating Webex. In the event of other issues, contact support@entrust.com for assistance.

Note: The following information from the Cisco WebEx technical documentation is relevant to this procedure:

"As an administrator, you use WebEx Site Administration to configure single sign-on for Cisco WebEx Messenger and Cisco WebEx meeting applications. The information that you use during configuration must be exact. If you require further clarification about the information required to configure SSO for your site, contact your Identity Provider."

For more information on setting up WebEx for Single Sign-On (SSO), consult the following Cisco technical documentation: "Configure Single Sign-On for WebEx".
