ESET Secure Authentication supports either single domain or multiple domain Active Directory environments. The differences between these environments and their installation requirements are detailed below.
Single Domain, Single Forest
This is the simplest configuration, and the installer may be run as any Domain Admin. ESET Secure Authentication is available to all users within the domain.
Multiple Domain, Single Forest
In this deployment, a parent domain such as example.corp has multiple sub-domains such as branch1.example.corp and branch2.example.corp. ESET Secure Authentication may be deployed on any of the domains in the forest, but there is no cross-communication between the installations.
In order to install ESET Secure Authentication on a sub-domain, the installer must be launched as a Domain Admin user from the top level domain.
For example, using the example domains defined previously:
To install ESET Secure Authentication on server01.branch1.example.corp, log on to server01 as the example.corp\Administrator user (or any other Admin from example.corp). After installation, ESET Secure Authentication will be available to any user within the branch1.example.corp domain.
Multiple Domain, Multiple Forest
This is identical to the previous environment, in that ESET Secure Authentication installations on separate forests are not aware of each other.
