The custom policy authentication is integrated and works fine for the users, created specifically to the current tenant. However, in case, when user is logging in using AD account from a different tenant, it throws an error, saying that the account is not found.

I have verified, that the App Registration for the SPA has the following keys set:

{

"signInAudience": "AzureADandPersonalMicrosoftAccount",

"accessTokenAcceptedVersion": 2,

}

There is another tenant setup and configured by me, that works fine with external users (from other tenants). I can't find what is the difference. Please advice.
