Indeed Certificate Manager can interact with Microsoft CA that are beyond the boundaries of the domain of Indeed CM server. Say, in a configuration, when an organization has several independent domains with an independent CA in each of them, and Indeed CM is deployed at only one of the domains. Meanwhile, the user accounts are the same in the domains.

The IndeedCM.MSCA.Proxy component allows to request and write certificates to devices using Indeed CM from all CA that reside beyond the domain where Indeed CM is deployed. In this case, the MSCA Proxy address is added to the usage policy of Indeed CM devices. The said proxy is deployed in an external domain with user directory and certification authority. When issuing a device, the Indeed CM addresses the MSCA Proxy, and the latter sends the corresponding request to the target certification authority using the Enrollment Agent certificate (which resides in the storage of a workstation with IndeedCM.MSCA.Proxy component installed). To install and configure the MSCA Proxy application, proceed as follows:

1. Create a service account to use with Microsoft CA in an external domain (see Creating a service account for working with Microsoft CA).

2. Configure the Enrollment Agent certificate template for the account created in the previous step (see Settings of certificate templates to use with Indeed CM) and issue a certificate for the account using this template (see Issuing the Enrollment Agent certificate).

   Warning
   The Enrollment Agent certificate has to reside in the certificate storage of a workstation (Local computer) with IndeedCM.MSCA.Proxy component installed.

1. 
   

2. Install the IndeedCM.MSCA.Proxy.msi component onto a workstation in a domain with external CA.

   Note
   System requirements for the component installation are the same as ones for installation of Indeed CM server.
