When adding accounts in the iRedAdmin console, I add a display name to the user account .(ex. John Smith)

If I login to SOGo and send a mail, the mail goes out properly with the name "John Smith".

If I login to RoundCube and send a mail, there is no name in the email message. It just comes through as "john.smith@mydomain.com"

I have to manually go in to each user account in RoundCube and click on "Settings" and then "Identities" and then add a name for "Display Name".

This is not good because after creating many user accounts, the users don't bother doing this, and all their emails go out with no name, and it does not look professional.

Is there a way to have RoundCube pick up the "Display Name" field I entered in the iRedAdmin console?
