Fedora directory users - Dec 2006 - migrating users from Tru64 to Fedora DS

Hi, I have 4 Tru64 servers with a lot of users and I want to unify the
authentication of them using FDS.
My idea is to install FDS on a fedora server with replicas if
possible. Have anybody done this before? Have  FDS  scripts to migrate
users/home_directory/UID/GID from a passwd file? What do you recommend
me? Can I use FDS as en LDAP server for Tru64 clients?

thanks in advance
regards;
Israel
