Request By Attribute - Delegation

The Delegation request type enables a department administrator to modify permissions on an organizational unit in a department OU. A department administrator can submit a delegation request to grant or revoke one of the defined permissions sets called delegations which are detailed in the Delegations Available section below. A department administrator can request multiple delegations by submitting multiple requests.

The Active Directory team maintains a set of PowerShell scripts at https://github.austin.utexas.edu/eis1-aad/RequestsByAttribute to assist department administrators with this process. These scripts must be run on a Windows system joined to the Austin Active Directory and the system must have the Active Directory PowerShell module installed.

Add-ADDelegationRequest.ps1 - submits a new delegation request for a department
Remove-ADDelegationRequst.ps1 - remove a pending delegation request for a department

The RequestedFor parameter notes that the department administrator is requesting the delegation on behalf of the xyz789 user.
