With v2.0, we have added support for Active Directory Federation Services (AD FS) and SAML 2.0. For customers that require Multi-forest AD support, they can use AD FS or SAML 2.0.
The customer is responsible for setting up and configuring AD FS. HCP Anywhere configuration with AD FS is documented in the admin guide and GSS can assist with the HCP Anywhere setup as needed.
SAML 2.0 IdP setup is similar to AD FS setup.
