Access Manager provides single sign-on (SSO) 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 sign in multiple times to access different services. You can sign in only one time with an existing password and Access Manager grants you access to all services.
This SSO 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 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.
Access Manager supports SSO to the following Office 365 applications:
SharePoint
Office 365 Portal
Outlook Web Access
Lync 2010
Lync 2013
Skype for Business 2015
Outlook 2013
