Creating a service account for working with the user catalog and system data storage

For Indeed Certificate Manager system to operate properly, certain rights to access Active Directory objects and certification authorities are required. You can distribute the privileges between several accounts, or create one with maximum rights for system management, depending on the requirements of the company security policy.

Create a service account (say, servicecm) to perform data saving and reading operations in the Active Directory storage.

Configuring the user catalog in Active Directory

Grant the created service account (servicecm) the necessary permissions to work with the object (domains, containers, organizational unit) where the Indeed Certificate Manager users will be located. This account will be used to read and write user attributes.

To do this, do the following:

1. Open Security property of the object (domain, container or unit) that contains the Indeed CM system users.
2. Click Advanced. Click Add. Click Select a principal.
3. In the Enter the object name to select text box, type service account (servicecm). Click OK.

   • Write pwdLastSet - Also required to be able to reset the user's password.
