I have deployed Azure AD B2C custom policies based on the SocialAndLocalAccounts example. Along with local accounts, the policy includes Google, Microsoft, and multi-tenant Entra ID providers.

I am currently facing issues signing users out of my application who were signed in with external IDPs.

When examining the Entra ID IDP, the https://login.microsoft.com/…/logout endpoint is being called without query parameters.

So far I have tried adding id_token_hint qyery parameter to B2C logout request.

I would expect the original Entra ID’s ID token to be passed to the Entra ID logout endpoint as a query parameter, and the user to be prompted to enter their Entra ID credentials the next time they sign in.

Any guidance on the matter would be appreciated. Thanks!
