Installing OpenManage Essentials

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 conguration 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 modied by adding registry entries to the ZoneMaps for HKLM and

HKCU. This ensures that Internet Explorer identies the fully qualied domain name as an intranet site.

A self-signed certicate is created and this certicate is installed in the root Certicate Authorities (CA) and My certicates.

To prevent certicate errors, remote clients must either install OpenManage Essentials certicate in both CA and Root Certicate

Stores or have a custom certicate 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

dierent on every system.

For the highest level of security, it is recommended that you use a domain service account that is specied during custom installation

for SQL Server.

At runtime, when the OpenManage Essentials website determines that it has an invalid certicate or certicate binding; the self-

signed certicate is regenerated.
