I had to recreate my certs and after doing so and importing them into my IIS, I'm struggling now to find where exactly on the Sitecore IdentityServer website I must update its Thumbprint.

Has anyone changed this value?

It looks like there is an XML instead of a config file on which we can do it.


  • Remember to recycle after changing this value. That had me stumped for a bit :)

    And also update /App_Config/Connectionstrings.config with the new thumbprints and be sure that IIS_IUSRS can access the private key, done in Certificates MMC: Right click certificate -> All Tasks -> Manage Private Keys -> Add group "IIS_IUSRS"
