As of Unity Connection version 10.5, all Unity Connection REST-based APIs support Cisco Single Sign On (SSO) authentication. When SSO is enabled on Unity Connection, all Unity Connection APIs become SSO-enabled.
What is SSO (Single Sign-On)?
Single Sign On (SSO) simplifies the login process for Users and Administrators in Cisco Unified Communications Products (Unified CM and Unity Connection releases 10.5).
SSO offers an easier, more consistent way for users and administrators to authenticate access to secured resources.
Instead of each product requiring a separate user name and password login, a single returned credential allows access to all enabled product interfaces.
Think of SSO as supplying the "skeleton key" to every enabled, authorized service and interface in your environment.
