After reading a nice paper by Val Henson[1] I'm not so sure I'd trust
sensitive information like password data to rsync without making sure
that compare-by-hash is disabled if at all possible.
There are other ways to use a common authentication server, shared by
many machines. Kerberos and NIS or NIS+ are good examples. At least
better than a ``blind copy'' of password files with rsync.
Giorgos.
