To associate a Unified CM or other server/service with the deployment:
1.
Go to Configuration > Unified Communications > and then Unified CM servers, or IM and Presence Service

.
2.
Click the server / service node name.
3.
In the Deployment field, select which deployment will enclose this server / service node.
4.
Click Save.
Note:
When you save this change, the Expressway-C refreshes the connection to the node, which may
temporarily disrupt the service to the connected users.
5.
Repeat for any other Unified Communications services that will belong to the deployment.
Single Sign-On (SSO) over the Collaboration Edge
Use this feature to enable single sign-on for endpoints accessing Unified Communications services from outside the
network. Single sign-on over the edge relies on the secure traversal capabilities of the Expressway pair at the edge,
and trust relationships between the internal service providers and the externally resolvable identity provider (IdP).
network. Single sign-on over the edge relies on the secure traversal capabilities of the Expressway pair at the edge,
and trust relationships between the internal service providers and the externally resolvable identity provider (IdP).
The endpoints do not need to connect via VPN; they use one identity and one authentication mechanism to access
multiple Unified Communications services. Authentication is owned by the IdP, and there is no authentication at the
Expressway, nor at the internal Unified CM services.

How it works
Cisco Jabber determines whether it is inside the organization's network before it requests a Unified Communications
service. If it is outside the network, then it requests the service from the Expressway-E on the edge of the network. If
single sign-on is enabled at the edge, the Expressway-E redirects Jabber to the IdP with a signed request to
authenticate the user.

authenticate the user.
The IdP challenges the client to identify itself. When this identity is authenticated, the IdP redirects Jabber's service
request back to the Expressway-E with a signed assertion that the identity is authentic.

The Expressway-E trusts the IdP, so it passes the request to the appropriate service inside the network. The Unified
Communications service trusts the IdP and the Expressway-E, so it provides the service to the Jabber client.
