Service Account Requirements
As a modular and scalable enterprise application built following a Services Oriented Architecture, EmpowerID uses Windows Services to host Job functions as well as WCF web services. Each of these Windows services requires a user identity (service account) with the necessary privileges to perform their designated tasks. Before you install EmpowerID, you should first create this service account, giving it the necessary access rights needed by EmpowerID to interact with the EmpowerID database, IIS application pools, the local machine on which EmpowerID is installed, as well as to perform any needed directory management operations. These rights are outlined below.
When you create the service accounts, you should use the following restrictions for security purposes:
- Deny users access to log on using Terminal Services.
- Deny users access to this computer on a network.
Required SQL Database Rights
Because each EmpowerID Windows Service accesses the EmpowerID database, service account users must have the right to alter the database on the target SQL server. Specifically, service accounts must have the following database capabilities:
|Required Windows Service Rights|
Alter — Needed on the following tables only to allow for truncation:
Required IIS Application Pool Rights
The application pool identity requires read access to the EmpowerID web site folders. If you are using SharePoint, the EmpowerID application pool requires read access to the SharePoint database and the SharePoint web site application pool needs the same rights to the EmpowerID database as the EmpowerID application pool.
Required Local Machine Rights
The EmpowerID service account interacts with the local machine to perform a variety of maintenance procedures, including the distribution and maintenance of new workflows and other Workflow Studio published items. The service account needs the following access rights on the local machine:
|Required Local Machine rights|
|Install files in to the local global assembly cache (GAC)|
|Read the registry|
|Read certificates in the local certificate store|
|Spin child processes|
|Run C# compiler in the background if and when necessary|
|Create files in the temp folder|
|Run remote PowerShell for Microsoft Exchange|
Create files and folders in the following locations:
Required Directory Management Rights
EmpowerID also utilizes highly privileged user accounts when connecting to user directories such as Active Directory, LDAP or database systems. These user "account stores" use saved proxy accounts for connecting to these systems and performing user account management operations. EmpowerID requires one privileged account per domain or directory. This account requires all of the privileges matching the functions that EmpowerID may perform (user creation, deletion, password reset, group creation, etc).
If you will be managing an Active Directory Domain, the proxy account must be able to access the deleted items container in AD. Access to the Deleted Items container requires Domain Admin access unless the container security is edited to allow non-domain admins to read it. Instructions for editing the security of the deleted items container can be found in the Microsoft Article, "How to let non-administrators view the Active Directory deleted objects container in Windows Server 2003 and in Windows 2000 Server" which can be viewed in full at http://support.microsoft.com/kb/892806.
Additional Required Rights
In addition to the above rights, the EmpowerID Worker Role Service and the EmpowerID Web Role Service each requires service accounts with additional rights. The specific rights needed by each service is as follows:

|EmpowerID Worker Role Service|
