GPOADmin 5.18 - Quick Start Guide

Configuring GPOADmin to use a Group Managed Service Account (GMSA)

To configure GPOADmin to use a Group Managed Service Account
1
Create the Key Distribution Services KDS Root Key. For details, see https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2012-R2-and-2012/jj128430(v=ws.11)?redirectedfrom=MSDN.
2
Create a Global security group and add the computers that will host the GPOADmin service.
3
Create the Group Managed Service Account for GPOADmin using the New-ADServiceAccount PowerShell command. For more details, see https://docs.microsoft.com/en-us/powershell/module/activedirectory/new-adserviceaccount?view=windowsserver2019-ps.
Set the -PrincipalsAllowedToRetrieveManagedPassword switch to specify the name of the global security group created in step 2.
Set the -ServicePrincipalNames switch for the default domain unique SPN. For example. to ‘GPOADmin/GPOADminService/domainxyz.microsoft.com'.
If you require multiple service accounts, set the value to 'GPOADmin/server.domain.com:port#'. For example, GPOADmin/DC1.domain.com:40200. See Managing client connections for more information.
* 
NOTE: The GMSA will not update the SPN automatically each time the service starts resulting in warnings in the GPOADmin event log. To prevent the service from updating the SPN, add the following to the registry of the GPOADmin service host if it does not exist:

Value name: UpdateSPN
Value type: DWORD
Value path: HKEY_LOCAL_MACHINE\SOFTWARE\Quest\GPOADmin\ServerConfig
Value: 0
4
Create a global security group and add the Group Managed Service Account. This security group will be used to grant permission to the service account.
5
For each computer that will host the GPOADmin service and that you added to the security group in step 2, do the following:
a
Restart the computer.
b
Run the following PowerShell command once the GPOADmin host computers have restarted to install the GMSA: Install-ADServiceAccount -Identity <service_account_name>.
c
Run the following PowerShell command to verify that the GMSA was successfully installed. The command will return True if the GMSA was successfully installed: Test-ADServiceAccount -Identity <service_account_name>.
6
Follow the Minimum permissions required for the service accounts and replace the service account with the group the GMSA member of create in step 4.
* 
NOTE: If configuring for SQL, enter the actual GMSA instead of the group when specifying a windows login.
Once the service is using a GMSA account, the password is retrieved from the LSA. This will disable the ability to stop the service or change the service account.
You can run the following command to switch back to a normal account:
sc <server> managedaccount [service name] [type]. For example, sc managedaccount "QGPMService" false.

Minimum permissions required for the service accounts

To set up minimum permissions for the service accounts
1
Create a service account and add it as a member of the Local Administrators group where the GPOADmin service is installed.
2
Grant this account Log on as a Service on the computer where GPOADmin is installed.
3
Grant the service account Full Control to the installation directory.
4
Create the "Quest" container for the configuration store in either Active Directory or AD LDS (depending on where the configuration will be stored.
COnfiguration Store
to create the Quest container...
Active Directory
Using ADSIEdit.msc, create a "Quest" container under CN=Services,CN=Configuration,DC=Domain,DC=com within the GPOADmin servers domain.
AD LDS (Preferred option)
 
Using ADSIEdit.msc, connect to the AD LDS instance, expand CN=Services and create the Quest container.
SQL
Skip this step.
* 
NOTE: ADSIEDit.msc is available from the Windows Support Tools or through Add Roles and Features.
5
Grant the service account access to the Quest container.
COnfiguration Store
TO grant the service account access...
Active Directory
1
Go to the properties of the Quest container.
2
Select the Security tab and click Advanced.
3
Click Add and select the service account. The applies to option should be This object and all descendant objects.
4
Delegate the following permissions in the Advanced Security Settings: List Contents, Read all Properties, Write all Properties, Delete Subtree, Read Permissions, Modify Permissions, Modify Owner, All Validated Writes, Create All Child Objects, and Delete All Child Objects.
AD LDS (Preferred option)
1
Connect to the AD LDS instance using ADSIedit.msc (for example "CN=Configuration,CN={AD LDS INSTANCE GUID}").
2
Expand CN=Roles and go to the properties of CN=Administrators.
3
Browse to the Member attribute and click Edit. Add the GPOADmin service account as a Windows Account.
NOTE: If adding the service account as a member of the AD LDS Administrators role is not possible, the AD LDS support tool dsacls.exe can be used to fine-tune the rights given by this role or grant specific rights to user accounts.
SQL
1
Run the database script GPOADmin.sql.
a
In Microsoft SQL Server Management Studio, select File | Open | File or press the control key and the O key (Ctrl + O).
b
In the Open File dialog, select the GPOADmin.sql file and press OK. This file is located in the GPOADmin server install directory by default, but if your SQL server is on a different computer, the file can be copied.
c
If you want to create the database with a different name other than the default name of GPOADmin, change the name from GPOADmin on line 4 and line 7 to the name you want to use.
d
Click the Execute button or press F5 to create the database.
2
Execute the InitializeDatabase stored procedure on the newly created database.
a
Create a new query by pressing the New Query button.
b
Set the available database to the name of your GPOADmin database or type USE [DATABASE_NAME] where DATABASE_NAME is the name of your GPOADmin database.
c
On the next line, type EXEC InitializeDatabase.
d
When ready, click the Execute button or press F5 to run the command.
3
Create a login for the GPOADmin service account.
a
In Microsoft SQL Server Management Studio, navigate to Security, then Logins.
b
Right-click Logins and select New Login.
c
On the General page, enter the name of the service account in the Login name field.
d
Select Windows authentication to connect as the GPOADmin service account or SQL Server Authentication to connect as a SQL account. SQL authentication is useful if you want to use this database as the configuration store for a GPOADmin installation in another untrusted domain.
e
Set the Default database property to the name of your GPOADmin database.
f
On the Server Roles page, check the public server role.
g
On the User Mapping page, under Users mapped to this login, check the name of your GPOADmin database. Under Database role membership for the selected database, check db_owner and public. Click OK to close the properties page.
6
Grant the service account Full Control on each WMI Filter that will be managed by GPOADmin.
Using ADSIEDIT.msc, expand the Default Naming Context partition, open ‘CN=SOM,CN=WMIPolicy,CN=System,DC=domain,DC=com’ and delegate Full control for All descendant objects.
7
Using GPMC, delegate Link GPOs to the service account on the Site and Domain level (or even on the OU level depending on where GPOADmin is required to manage GPOs), for This container and all child containers, if child containers are needed.
8
For the service account to run RSoP reports, the Read Group Policy Results data right must be granted. Using GPMC, delegate Read Group Policy Results Data to the service account on the Domain level (or even on the OU level, depending on where GPOADmin is required to perform the RSoP analysis), for This container and all child containers, if child containers are needed.
For each computer that will be targeted during the RSoP analysis, add the service account to that computer’s local Administrators group.
9
Using GPMC, delegate Create GPOs to the service account on the Group Policy Objects Level.
10
Using GPMC, delegate Edit settings, Delete, and Modify security to the service account for each existing GPO that will be managed by GPOADmin using GPMC.
11
For each GPO managed by GPOADmin, verify that the service account has direct ownership of the GPO on the Owner tab of the Advanced Security Settings dialog box.
* 
NOTE: This step can be automated after GPOADmin has been installed and configured using the GPOADmin.AddServiceAccountToALLGPOs.ps1 PowerShell script located in the Scripts directory of the install directory.
12

To ensure that GPOs created in GPMC and then registered in GPOADmin can be deleted and are not missed during a check in, the Service Account must have the Delete Subtree right on the required GPOs.
16
For each GPO managed by GPOADmin, the Service Account must have ownership of the GPO. This is required in all environments to ensure that modifications made to the delegation of a GPO can be properly applied. You can verify direct ownership of the GPO on the Owner tab of the Advanced Security Settings dialog box.
17
Repeat steps 7 to 16 for every domain that will require GPOADmin to manage its GPOs.
18
The service account requires rights to create a Service Connection Point on computers where GPOADmin is installed.
To do so, open ADSIedit.msc or DSA.msc and connect to the Active Directory domain. Navigate to the computer where GPOADmin will installed, the computer properties, and select the Security tab. Grant the service account the following permissions: Create serviceConnectionPoint objects and Delete serviceConnectionPoint objects for This object and all descendant objects.
19
Install GPOADmin using the service account.
For more information about the installation, see Installing Quest GPOADmin .
20
Connect to GPOADmin as an Enterprise Admin or the service account.
Only these accounts are granted access to change the configuration during the install of GPOADmin.
21
Make sure the service account has access to the desired configuration and backup storage locations. Then, step through the Server Configuration Wizard.
You can add GPOADmin trustees to connect to the system or change server properties.
For more information about the configuration, see Configuring the GPOADmin Server .
22
Once the product has been configured, connect to the GPOADmin console using the service account. Configure any additional administrators and users (trustees) that will connect to the product by
right- clicking the connected domain and selecting Options and then Access. Delegate any roles required by these users through the Version Control Root properties, or any registered OU/GPO within the Version Control Root as necessary.
23
Connect to GPOADmin as any account granted rights to connect during the Server configuration setup.
* 
NOTE: The Watcher Service requires that the service account created in step 1 has the “Replicating directory changes” permission on the Default Naming Context (DC=domain, DC=com) and the Configuration Context (CN=Configuration, DC=domain, DC=com) for this object and all descendents.
* 
NOTE: The service account must have List folder contents, Read, Write, and Modify on the Scripts folder in SYSVOL.
