Error: SAML authentication not supported

Who can use this?

Plans:

  • Enterprise

Permissions:

  • System Admin

Find out if this capability is included in Smartsheet Regions or Smartsheet Gov.

Cause

  • Plan account doesn't have SAML enabled
  • User isn't attached to the plan
  • Old login data
  • Email attribute in SAML assertion does not match an existing Smartsheet user account

Resolution

  • Have a System Admin go to Admin Center and navigate to Menu > Settings > Authentication to ensure that the toggle for your SAML IdP is turned on.
  • Add the user to your plan.
  • Clear cache and cookies or try an in-private/incognito browser session.
  • Capture and analyze an assertion. Ensure the email address passed in the email attribute is the primary email address, or a confirmed secondary email address, on the user's Smartsheet account. You may need to work with your IdP admin to verify the profile is up to date in their company's IdP.
