/etc/passwd maps names/userinfo to user id's.
/etc/group does the same thing for group id's.
When you get rid of a user account, you should use the userdel command
which does the exact opposite of useradd, then run periodically
find / -nouser -print
This will give you a list of all the files on the filesystem which are
owned by a userid which is no longer in /etc/passwd (-nogroup also
does what you would expect)
find / -nouser -print | xargs rm
is a good method for cleaning up after old user accounts, once you
make sure the find command is locating only those old files.
(you have to be careful since rpms and tar files sometimes contain
files with userid's foreign to your machine, and you don't necessarily
want to delete all them)
If you want to make all the 'unknown user' files owned by root (and
group root) instead, simply run:
find / -nouser -print | xargs chown root.root
