If you just want to do LDAP SIMPLE BINDs with username/password 
(hopefully over a TLS connection), and use the Kerberos password instead 
of the userPassword attribute, you can use the PAM passthru bind 
plugin.  You will have to grab the Fedora DS source and build it.  What 
this does is pass the BIND authentication request to PAM, which you can 
configure to go to Kerberos for authentication.
