Kerberos5 should work fine; direct support for LDAP is a problem for 4.x
due to a lack of complete NSS support--to do this directly, you'd need to
run 5.x.  My understanding is that some sites dump their LDAP databases to
NIS databases and share them on the FreeBSD side using NIS, which is also
a reasonable (if less secure) solution.  If you just want to use Kerberos5
for password sharing, 4.x should be no problem at all.
