No, this is a feature. You can indeed cut and paste the encrypted
password field from one box to another - I've done this several times.
However, the `passwd' command chooses a random salt when it hashes the
password entry so that they do NOT look the same. Admittedly, this was
more of an issue before shadow passwords existed; it was an attempt to
make it non obvious that two encrypted passwords were indeed the same.
I hope that makes sense :) Your concerns about moving accounts are
unfounded.
Cheers,
