Single Sign-On for Collaboration (SSO)

Using a SAML or OIDC identity provider so users authenticate once to CUCM, Unity Connection, Expressway or Webex services.

Definition

Collaboration SSO redirects users to an identity provider such as Microsoft Entra ID (formerly Azure AD), Okta or AD FS, which returns a signed assertion. CUCM and Unity Connection support SAML SSO, and Webex Control Hub supports SAML integration so Webex App users log in with corporate credentials. MRA supports SSO with OAuth refresh tokens.

Example

Webex App users are redirected to Microsoft Entra ID to sign in with MFA before accessing Webex.

Exam tip

SAML SSO requires metadata exchange between the service provider and IdP and accurate time sync.
