where is the 'DisplayName' stored?

[neo20]

The default Display name is the name before @ in email address (eg. admin@localhost.com is admin ), it can be configured in "Setting -> Identities '.

I've just created nearly 100 accounts for my coworkers with a bash and sql scripts. I also want to change the display name at one time?

But where is the 'Display Name' stored? I've search in /home and database , need help. thanks

It's set in the Identities table of roundcube's database.

Thanks! you're right.
I've looked up it in the wrong database . (there's a mails database used by a plugin)
