Re: User management
You are in deep trouble my firend, you need to change the user-id,
your system is really messed up :)
clear the mess, and make user id unique for every user.

Re: User management
Yes, and you are seeing that already. Use the command:
logins -d
And you'll see the problem. A user name is nothing more than a symbolic name, similar to a hostname. The UID is the real ID, while the username is just an alias to the UID number.
Additionally, hackers will often hijack a username and change the UID to 0, thus ctreating a duplicate root user (a big security problem).

Re: User management
This is a bad config, I have encountered it already at one of our customers. The thing is that they interpreted the unix rights wrong. For this they should have used the GID. For easily changing the UID, use my performance-optimized script:
http://viktorbalogh.net/blog/languages_scripting/advanced-scripting-changing-the-uid-of-a-user
It starts parallel (find├в ┬ж.chown) processes to get the job done as fast as it can be.
