36 Sentinel 6.1 Installation Guidenovdocx (en) 7 January 2010 Log Directory Archive Directory Determine the SQL Server Instance port number (the default port number is 1433).The Sentinel system uses several accounts for installation and system operation.These accounts existin the Sentinel database and might use SQL Server authentication or Windows authentication. Touse Windows authentication for one or more of the Sentinel users during Sentinel installation, thecorresponding Windows Domain user must exist before installing the Sentinel Database.The domain user should have Power User privileges to start the Sentinel services. See Section 3.4.1,“Providing Power User Privileges to Domain Users,” on page 33 for more information.The following Sentinel users can be assigned to a Windows Domain User: Sentinel Database Administrator, used as the schema owner (named esecdba by default, ifusing SQL authentication; might be any domain account if using Windows Authentication). Sentinel Application User, used by Sentinel applications to connect to the database (namedesecapp by default, if using SQL Authentication; might be any domain account if usingWindows authentication). Sentinel Administrator, used as the administrator for logging to the Sentinel Control Center(named esecadm by default, if using SQL authentication; might be any domain account if usingWindows authentication). Sentinel Report User, used for creating reports (named esecrpt by default, if using SQLauthentication; might be any domain account if using Windows authentication).NOTE: The database contains the Sentinel Database Administrator user, Sentinel Application User,and Sentinel Administrator user by default.Sentinel does not support Microsoft clustering or High Availability for Windows.After installing the Sentinel Database on SQL Server using local authentication, the databasecontains the following users: esecdba: Database schema owner. The DBA privilege is not granted to the Sentinel DatabaseUser because of security concerns, so to use Enterprise Manager (the GUI for the SQLdatabase), you must create a user with DBA privileges. esecapp: Database application user. This is the application user used to connect to the database. esecadm: Database user that is the Sentinel Administrator. This is not the same user account asthe Sentinel Administrator operating system user. esecrpt: Database report user. sa: System administrator database user.3.4.3 Authentication Mode Settings on Microsoft SQLOn Windows, you need to install SQL Server with mixed mode authentication to log in to theSentinel Control Center using either Windows or SQL Server authentication. If you install SQLServer with Windows authentication, you can log in through Windows authentication only.
