[Fedora-directory-users] Samba integration

Hello, I have seen Fedora Directory Server console has support for "NT User" attributes when creating a new user in the directory. However, it seems the enabling the "NT User" capability uses an objectclass named "ntuser" instead of using "sambaSamAccount", which is the correct objectclass for Samba 3.0 integration. Can this be changed? Also, Fedora Directory Server has a plugin for Password Modify (LDAP_EXTOP_PASSMOD) which requires the invoker to always supply the original password along the new password. This causes problems when trying to use password synchronization between Samba and FDS, since Samba can't supply the original password. Can this be changed? It seems to me the only way of fixing this is by modifying the source file sources/ldapserver/ldap/servers/slapd/passwd_extop.c, but the building process seems overwhelming for me to try. Any ideas? Thanks!
