Код:

Get-ADGroup -fil {DisplayName -like "*DIT*" -and GroupCategory -eq "Security"} | Get-ADGroupMember  | Get-AdUser -Properties Description | Where {$_.Description -eq "Директор"}

Или так:

Код:

Get-ADGroup -filter {DisplayName -like "*DIT*" -and GroupCategory -eq "Security"} | Foreach { Get-AdUser -filter {Description -eq "Директор" -and MemberOf -RecursiveMatch $_.DistinguishedName}}
