How to Add Domain to the Forest Tree and Update Domain Credentials
Add New Domain
When AD Reports starts, it loads all domains and trusted domains associated with the current forest. Subsequently, it constructs a domain tree labeled under the forest name as "Current Forest."

As a default setting, the "My Saved Domains" node remains without any content. If you require to use custom credentials to establish a connection with the domain, or if you intend to utilize a specific account for executing scheduled reports within the designated domain, you have the option to add that domain to the domain tree. This action will result in the domain becoming visible under the "My Saved Domains" node.
To add a new domain into the domain tree, select "Add Domain" from the Domain menu.

Enter Domain Credentials
Enter Domain name, username, and password accordingly.

Test Domain Binding
Ensure the verification of domain bindings by selecting the "Test Binding" button. Upon successful binding, you will see the message "Successfully bound to [domain name]."

Click OK and the new domain will be added to the "My Saved Domains" section of the Domain tree.

Update Existing Domain Login Information
To update the domain login and password details in AD Reports, select a domain from the "My Saved Domains" section, then choose "Edit Domain" from the Domain menu. Follow the same procedure as you would when adding a new domain to enter new credentials and test the binding.

After pressing "Save" button, the new login / password information for the selected domain will be updated and all scheduled reports, using this account will be refreshed with new credentials.
