NetIQ Access Manager provides single sign-on access to Office 365 services such as Exchange Server, Sharepoint Online and Lync without using ADFS (Active Directory Federation Services). You can use your existing enterprise credentials to access any of the Office 365 services without having to remember multiple passwords or sign in multiple times to access different services. You can sign in once with an existing password and Access Manager grants you access to all services.
This single sign-on access is achieved by implementing Passive or Active authentication by using WS-Federation, WS-Trust, and SAML 2.0 protocols.
A trust model is set up for Access Manager and Office 365 to communicate with each other. Access Manager, configured as an identity provider, allows Office 365 to trust it for authentication. Office 365 configured as a service provider, consumes authentication assertions from Access Manager.
