Hi
I am trying to use following article to get ADFS working with Azure AD B2C in the start almost 3 weeks ago it worked and now I am getting this error.
https://video2.skills-academy.com/en-us/azure/active-directory-b2c/identity-provider-adfs2016-custom?tabs=app-reg-ga
The error that I am getting is
"AADB2C90168: The HTTP-Redirect request does not contain the required parameter 'Signature' for a signed request."
I removed my Custom policy and took on a vanilla policy from starter pack and configured ADFS but had same result.
There is no guidance on AADB2C90168 on the Internet on this error.
The ADFS is using a Public certificate and AzureAD B2C is using self-signed certificate (as described in Pre-Requisite section).
Any help will be appreciated.
