Final answer:
The management, expiry, and renewal of SAML certificates is typically the responsibility of the customer, who must monitor and renew their certificates, although support might provide assistance depending on the SLA.
Step-by-step explanation:
The management, expiry, and renewal of SAML certificates is generally the responsibility of the customer. In the context of a service provider or identity provider, the organization using the SAML protocol for single sign-on (SSO) will need to manage their own certificates. This includes monitoring the certificates for expiry, renewing them before they expire, and ensuring that the new certificates are properly deployed across all necessary systems.
The support team may assist or guide the customer through the process, especially where managed services are concerned, but ultimately it is the customer's obligation to maintain the health of their SAML certificates. Support teams do not usually have the authority or access to directly manage the customer's certificates. However, the degree of involvement by support services can vary depending on the service level agreement (SLA) between the customer and the service provider.
