Identity - Display Name - Uses system username

[L4UR3NS]

Hi all,

I'm running Virtualmin on Ubuntu with Roundcube on a subdomain.

The problem I'm facing is that when a new user logins, the identity is incorrect.

The Display Name is being formatted as "username-domain.tld". Its not necessarily incorrect, since this is the username it gets on the system.

The question is: How can I somehow force it to not create a Display Name at all, or another one? Where can I find the piece of code that specifies this?

I'm not sure if the answer is somewhere on the forum already, I did search. And I've been Google's best friend lately, without success.

Thanks in advance.
