[Satosa-dev] Federeated domaian in AAD authenticate with IDP pysaml2 sample.

Hi all, I configured a federated domain in my Azure AD tennant to be authenticated against an IDP based on pysaml IDP sample. When I try logging in https://portal.azure.com with an user at myfedereteddoaim.com, following error happens: AADSTS50008: Unable to verify token signature. The signing key identifier does not match any valid registered keys. Any suggestions? Thanks in advance. Regards.
