    IDX10503: Signature validation failed using UmbracoIdentity on Windows 2016 server

    Hi,

    We created a member driven site by using UmbracoIdentity in Umbraco 8 to authenticate members against a ADFS server. This works fine on a local development enviorment but we now would like to use it on a Windows 2016 production server.

    When opening the site, the ADFS server authenticates properly but when in comes back to our webserver the error: IDX10503: Signature validation failed. Keys tried: '[PII is hidden]' occures. Where using Sectigo Positive SSL certificates on this site with 4096 bits encryption.

    I Googled a lot to find a solution but i don't see how i can fix this problem. Is there someone who had the same problem/error using UmbracoIdentity?

    Best regards,

    iNETZO

    It turned out that on the ADFS server for the domain were set to SHA1 instead of SHA256. If someone encounters the same problem, this may be a cause.
