Does that mean it only supports Azure AD B2C? Or can it support any AAD login, including internal, corporate ones, over OIDC?

You can configure yourself the accounts that you can login with.

In the configuration block, there's a `tenant`  section in which you specify if you want any Microsoft account (@microsoft.com, @outlook.com, @hotmail.com, younameit), or you only want accounts from a specific organization to login.

I was confused because to me that’s not really a “social” login

This is interesting because while Kratos doesn’t support LDAP, if it supports AAD then that’s a pretty useful “enterprise” feature that might be a good enough substitute
