Yes it works, just choose different usernames but assign them all to
the same uid and gid numbers and home directory. You'll have to
edit /etc/passwd (or NIS) manually; or use the adduser command
with the -o option to allow non-unique uids.
Also note that for each username/password, the operation of the
account will appear identical, except:
* The $LOGNAME environment variable will be set to whichever
username was used to log in (see the manpage for login(1)).
* File ownerships (such as if you do ls -l) will appear to be owned
by the first user in the passwd file with that uid. If you're using
NIS it will appear random (do to sorting by hash values).
