Kerberos accepting saml?--config

[C G]

Dear Kerberos Gurus

I am sure you might have already have done the following 

KDC to accept a SAML Authentication Statement or even an Attribute Statement and produce a Kerberos ticket

If the above is not possible, can we do below? 

to configure Kerberos with a web-based authentication system _in lieu_ of native password integration typically with an ldap/ad. If so, any literature available to do this?

Many thanks in advance

With best regards
