WebEx Single-Sign On FAQ


 

Question Index

 

What is Single Sign On (SSO)?
Single Sign On to WebEx Services allows users to authenticate to their corporate network and schedule and host WebEx Web Conferencing without having to login with a separate WebEx Web Conferencing username and password.

How is Single Sign On to WebEx Services accomplished?
Custom SSO API pages
One approach involves deploying custom WebEx Web Conferencing SSO web pages onto the customer's network. User's can develop their own custom SSO web pages using the WebEx Web Conferencing URL or XML API's or the WebEx Web Conferencing Professional Services team can develop them.

Users can access these custom SSO web pages only after authenticated to their corporate network. The custom SSO web pages automatically pass the user's WebEx Web Conferencing username and password via the WebEx Web Conferencing URL or XML API's to authenticate the user with the WebEx Web Conferencing site. Usually the custom SSO web pages can automatically create a WebEx Web Conferencing account if the user does not have an account on the WebEx Web Conferencing site. Typically user's do not know their WebEx Web Conferencing password's which prevents them from accessing the WebEx Web Conferencing site outside of their corporate network.

SAML / ADFS SSO
WebEx Web Conferencing also supports SSO via identity federation standards including SAML and Microsoft ADFS. This approach requires customers to have an identity mangement system (IDMS) like CA SiteMinder, that supports SAML 1.1, 2.0 or ADFS 1.0 federation.

With SAML / ADFS SSO, the customer's identity management system controls access to the WebEx Web Conferencing site. Users will first authenticate to their corporate network. When a user requests access to the WebEx Web Conferencing site, the IDMS will validate the user and generate a digitally signed SAML or ADFS assertion with the user's WebEx Web Conferencing username. WebEx Web Conferencing will validate the assertion signature and authenticate the user to the WebEx Web Conferencing site.
