read-only ftp user possible or not?

[DRaGoNx]

Hello, i have a little help request.

On one domain, i have created 2 ftp users through the panel.
I would like 1 to be read-only on the domain.

Is it possible or not? if yes, how to do it.

PS: i have tried to manage it through ispcp mysql dB, but when changing the UID / GID for the user, he cannot connect at all.
And if i'm not wrong, both users have the same GID/UID on the server files, so i cannot chmod them.

Thanks for your help.
