eap-ttls and eap-peap

I'm trying to see if it is possible to have eap-ttls and eap-peap
supported by a freeradius server. We currently use eap-ttls. Is it
possible to also have eap-peap supported by the same server?

I've searched for this sort of thing in the archives, but I can't come
up with a search that discussed this particular topic.

The how-tos and such that I've seen about eap-peap seem to indicate
that we would have to configure samba with winbind, and join the AD
domain to make this work, if it can at all. We currently use a
Kerberos KDC for the eap-ttls authentication. Is it possible to use
the same KDC for eap-peap, or is it only a Windows AD authentication?

Any obvious pointers to rtfms or previous threads will be accepted
humbly. Any specifics for trying things out would be also greatly
appreciated.

Thanks very much.
