Yes but you would have to configure it yourself. sssd would work nicely 
with an ldap/krb5 configuration.

You would need to either build your own Fedora 14 ipa-client v2 package 
or manually configure it. The sssd in F-14 should work well even using 
the ipa provider.

Windows domain login is not supported.

You cannot do a straight upgrade, too much changed between the two 
versions. You should be able to migrate the users and groups using the 
v2 migration system. This will maintain your user passwords at least. 
You would need to generate new principals and keytabs for your 
kerberized services.

I don't think it would be practical to try to run the two systems 
side-by-side.
