Terms and conditions for using Relational Database Management
Systems
The Relational Database Management System (RDBMS) used for installing OpenManage Essentials is Microsoft SQL Server. SQL
Server has conguration settings separate from the OpenManage Essentials database. The server has logins (SQL or Windows) that
may or may not have access to the OpenManage Essentials database.
When OpenManage Essentials is installed, Internet security is modied by adding registry entries to the ZoneMaps for HKLM and
HKCU. This ensures that Internet Explorer identies the fully qualied domain name as an intranet site.
A self-signed certicate is created and this certicate is installed in the root Certicate Authorities (CA) and My certicates.
To prevent certicate errors, remote clients must either install OpenManage Essentials certicate in both CA and Root Certicate
Stores or have a custom certicate published to client systems by the domain administrator.
For a typical installation of OpenManage Essentials:
• Use the local instance of SQL Server that has all supported components.
• The RDBMS is altered to support both SQL and Windows authentication.
• An SQL Server login user is generated for OpenManage Essentials’ services. This login is added as a RDBMS SQL login with the
dbcreator role and given the db_owner role over the ITAssist and OMEssentials databases.
NOTE: The password for the typical install, auto generated SQL Server login account, is controlled by the application and
dierent on every system.
For the highest level of security, it is recommended that you use a domain service account that is specied during custom installation
for SQL Server.
At runtime, when the OpenManage Essentials website determines that it has an invalid certicate or certicate binding; the self-
signed certicate is regenerated.
