• Because Unified CM SSO is SP-initiated only, IdP-side objects created before Enable SAML SSO completes are not used by Unified CM, so removing them before that point does not affect Unified CM sign-in. inferred in context
• The IdP NameID format must be urn:oasis:names:tc:SAML:2.0:nameid-format:transient. in context
• Multiple certificates in the signing and encryption portion of the SAML assertion are not supported. in context
• Cisco Collaboration SAML SSO supports SAML 2.0 service-provider-initiated SSO only. in context
• The IdP must send a claim named uid whose value maps to the LDAP attribute used as the Unified CM user ID, for example sAMAccountName. in context
