Weird issue with MFA for Guest Users
Hey,
we have implemented MFA for external Guest Users in Entra ID. It is working fine for every external user so far. However, there are two users from the same external company who cannot get into our environment since the implementation. Both of them receive the following error when trying to login:
AADSTS500082: SAML assertion is not present in the token.
When I check their Sign-In Logs, I see this “error”:
User needs to perform multi-factor authentication. There could be multiple things requiring multi-factor, e.g. Conditional Access policies, per-user enforcement, requested by client, among others.
They also told me that they are not prompted with MFA. Their company does not have MFA configured. However, they are using MFA with other external environments just fine.
I tried revoking their MFA settings and their sessions. We also tried different browsers, private browser sessions and deleting cookies. Nothing has worked so far.
Does anyone have any idea what could cause these issues?
