CUP - disable password notification

Dear Experts,

As we know, CUP will send notification of userid/password of each system after provisioning done. Can we disable this function?

Our scenario is:

1. we need to provision user id to EP and CRM at the same time.

2. user only allow to login EP

3. after user login EP, SSO ticket will be assigned to user to let user access CRM back-end applications

So, we don't want to send the password of CRM back-end system to new users. Can we achieve this?

Thanks a lot!
