Zextras Admin create new account password field not present

Hi,
i installed zimbra 8.8.15 and zextras in trial mode to evaluate the possibility to migrate our mail server.

I delegated to an account the admin of one domain.

If i login with the delegated account, when i create a new account, the field for the password are not present on the windows. After i create the account, i can go to manage account and here i can put the password.

Is this correct or there is a configuration to enable the password field on creation?

Thanks
