Assign it
The role ID is the same in every tenant, so these work as they are. Make it eligible through PIM:
Connect-MgGraph -Scopes "RoleEligibilitySchedule.ReadWrite.Directory"
$user = Get-MgUser -UserId "jane.doe@contoso.com"
New-MgRoleManagementDirectoryRoleEligibilityScheduleRequest -BodyParameter @{
Action = "AdminAssign"
Justification = "Needs Authentication Extensibility Administrator for <reason>"
RoleDefinitionId = "25a516ed-2fa0-40ea-a2d0-12923a21473a"
DirectoryScopeId = "/"
PrincipalId = $user.Id
ScheduleInfo = @{
StartDateTime = (Get-Date).ToUniversalTime().ToString("o")
Expiration = @{ Type = "afterDuration"; Duration = "P180D" }
}
}Who already has it?
Connect-MgGraph -Scopes "RoleManagement.Read.Directory"
Get-MgRoleManagementDirectoryRoleAssignment -Filter "roleDefinitionId eq '25a516ed-2fa0-40ea-a2d0-12923a21473a'" -ExpandProperty Principal |
