Mixed authentication in Sharepoint?

Question

SharePoint

Sharepoint 2013 sp1 RUS, windows server 2012.
Is it possible to authenticate the same domain user to the same site through different zones? For example, Kerberos in the windows domain in the default-zone and Form Based Auth in the Internet-zone, but for the same user. And it turns out that if I use authentication through FBA, then this is not the same user as the one who authenticates through Kerberos, even though these authentication methods are configured for the same Active Directory according to the settings?
Or is FBA not suitable for this solution? There is also SAML, maybe he does it?

Answer 1

Similar opportunities can be made through AD FS (+ He still knows how to do SSO) for the Internet and on the intranet he will be able to enter different zones from the inside.
