Single Sign On system is an access control system for independent software systems, which allows the user to have a single username and password for all the systems. If ISL Conference Proxy is set up to use External Authentication (as described in this topic - External Authentication) then ISL Conference Proxy communicates directly with the system that holds the user database. However with Single Sign On setup ISL Conference Proxy (service provider) communicates with an Identity Provider, which in turn communicates with systems holding user databases. This adds another layer of security and offers users a single authentication point for different and completely independent software systems. In the Single Sign On setup the credentials and authentication information are exchanged via the SAML (Security Assertion Markup Language) standard between Service Provider and Identity Provider.
We have tested and provide examples for integration with the following Identity Providers:
- Active Directory Federation Services (AD FS)
