RBAC: Remote Scripts

  • Article

Ever wanted to execute commands on Exchange server other than built-in Exchange cmdlet in remote powershell session?

Exchange 2013 onwards RBAC model introduced "Unscoped Role Management" management role which allows creating management role without specifying parent role. Beside putting only cmdlets (management entries) inside management role, unscoped role allows assigning scripts as a management entry.

This topic will address following scenario:

  1. Administrator have access only to Exchange remote PowerShell over Internet,
  2. Administrator needs to have ability to execute Get-Service cmdlet only on Exchange servers.

I have already prepared Get-Service.ps1 script and it is available for download. Note: Details how to create proxy script Will be covered in one of the upcoming posts.

Copy script Get-Service.ps1 in { Exchange Install Path }\RemoteScripts (usually "C:\Program Files\Microsoft\Exchange Server\V15\RemoteScripts")

Now it's time to create unscoped management role and assign coresponding management entry.

 New-ManagementRole -Name "HelpDesk Scripts" -UnScopedTopLevel -Description "Role will contain HelpDesk scripts"
Add-ManagementRoleEntry "HelpDesk Scripts\Get-Service.ps1" -UnScopedTopLevel -Parameters Name, ComputerName, ShowOnlyExchangeServices

Management role must be linked to role group which leads you to two options:

  1. Create new role group,
  2. Link management role to existing role group.

In this example I'll link management role to the existing "Organization Management" role group:

 New-ManagementRoleAssignment -Name "HelpDesk Scripts - Organization Management" -SecurityGroup "Organization Management" -Role "HelpDesk Scripts"

After all steps are done, create new session to the remote Exchange shell and you should see Get-Service.ps1 script included in remote commands:

 Get-Command Get-Service.ps1 | Select-Object Name, Source

Name            Source
----            ------
Get-Service.ps1 tmp_smlv3kdj.nfc

Get-Service.ps1 -ShowOnlyExchangeServices
