help creating new domains

i have created a new virtual webserver on my server.
until now users created like
uid=501(user) gid=501(user) groups=501(user)
uid=502(user2) gid=502(user2) groups=502(user2)
now the latest
is created like
uid=508(user3) gid=506(user3) groups=506(user3)

i mean until now uid, gid and groups was the same. but with the last server uid is not igual. how to fix this., and for future sites to be all iguals?

It’s not possible to make the UID and GID always be the same.

It’s possible to add groups without adding a new user, or add a new user without adding a new group… and because of that, the numbers won’t always line up.
