SAML Token
Authentication
In the 6.0
release,
Site
Recovery Manager
interacts with both vCenter Server (as before) and
Platform Services Controller (PSC).
The PSC contains a Lookup
Service to locate other services, a Licensing Service to replace the VIM
license manager, and Single Sign On (SSO) service for authentication and token
acquisition.
The vCenter Server management
node contains a new Tag Manager to create categories and tags for Storage DRS
or SPBM, and a new Authz service to replace the VIM authorization manager.
Management (M) and PSC
(N) nodes

When programs connect to the
local or remote SRM server, they must obtain a SAML token from the SSO service
on the local or remote PSC. (The older login functions implicitly obtain a SAML
token.)
