Web Applications – Apps and Additional User Accounts

Some apps let you create and manage user accounts directly in Plesk. For
example, the SugarCRM app allows you to add SugarCRM users without
logging in to the app. All apps with such “account services” can
associate their accounts with users of a Plesk subscription (additional
users). To perform such an association, you should grant the additional
users access to that account service (in the same way as you grant
access to apps). For details on account association, refer to the
section Linking Apps and Additional User
Accounts.
