DA files belong to first user?

[jouwnaam]

Today I added the first user to a new DA server. One day later this user had 19MB of disk space usage without ever login in.

So I did this at the shell to find what this user really occupied:
find / -user username > /root/user.txt

and found that lots of files "belonged" to the first user (not admin) on every DA server I have!

Could someone please confirm this?

I dont know about confirming it properly but I have noticed multiple instances when in the shell files are not owned by admin diradmin or root but instead owned by a user which is normally my own account as it was the first on the system, I haven't really investigated it much tho.
