Hi @rwmkwok

Are you working with a Smartsheet Partner? A partner can help you expedite this.

rwmkwok

We are your client to acquire service to register Smartsheet (SaaS) into our ADFS server for SSO. However the SSL certificate of sso.smartsheet.com was expired on 18 Feb 2025. Could you please share the new SSL certificate for renewal in our corporate ADFS server.

rwmkwok

The FQDN of my company is mtr.com.hk and the HQ is hosted in Hong Kong. The account manager of Smartsheet is ellie.mcphee@smartsheet.com.

Please kindly render your assistance to assign technical support to work with us to resolve sign-on issue.

Hi @rwmkwok,

Our team recently investigated an issue with SAML certificates expiring in February 2025. The XML data has now been updated on our XML URL. If you use signed authentication requests then you should update the relevant values in your IdP with the appropriate new information from the updated XML file - found in this article: Configure SAML for domain-level single sign-on to Smartsheet.

I recommend reaching out to your IT department and/or whoever handles your SSO configurations for assistance with the above.

Please follow up on your Support case if you have any additional questions.

Hope that helps!

Georgie

With reference to the screenshot of the current configuration of "Relying Party Trust" configured in our ADFS server, it's indicated that the SSL certificate of "sso.smartsheet.com" was expired. As said before, please share source file of the latest SSL certificate of "sso.smartsheet.com" to me for renewal (highlighted in GREEN arrow of the screenshot) in ADFS server.

The case has not been resolved. Please refer to the screenshot of the last email sent to Smartsheet for the details of the current issue.

rwmkwok

In summary, please render your assistance with priority to share the latest SSL certificate file (sso.smartsheet.com) to me for importing into the existing "relying party trust" in our ADFS server.

rwmkwok

The sign-in issue is still persisted and the issue is caused by the SSL certificate expired. We need the source file of your SSL certificate to import into our ADFS server.

rwmkwok

Please render with priority to seek your technical support team to address the issue by sharing the latest SSL certificate to me to fix the sign-in issue.
