NTP Setup
In SAML SSO, Network Time Protocol (NTP) enables clock synchronization between the Unified Communications applications and IdP. SAML is a time sensitive protocol and the IdP determines the time-based validity of a SAML assertion. If the IdP and the Unified Communications applications clocks are not synchronized, the assertion becomes invalid and stops the SAML SSO feature. The maximum allowed time difference between the IdP and the Unified Communications applications is 3 seconds.
Note |
For SAML SSO to work, you must install the correct NTP setup and make sure that the time difference between the IdP and the Unified Communications applications does not exceed 3 seconds. |
