> Greetings,
>
> I have need to produce a list of users from one list that exist in a second list (or more accurately, those who exist in both lists). Here is a bit of code that I came up with (which works):
>
> `# Large group that contains many users from many OUs$grp1 = "Big_User_Group"# Smaller group containing users from only a few OUs - it is a group of groups$grp2 = "Focused_User_Group"$a = Get-QADGroupMember $grp2 -SizeLimit 0 -Indirect foreach($User in $a) { if (Get-QADMemberOf $User -Name $grp1) { "{0,-30}{1}" -f $User.Name,$User.ParentContainerDN }}`
>
> It is pretty basic in approach, fairly non-elegant and quite slow (or should I say ponderous). Additionally, if I wanted to expand this to include additional groups (say I wanted to locate someone in 4 groups), I think it would get even slower.
>
> Did I miss the boat on this. I tried looking through the forum, but wasn’t sure exactly what to look under. Any input would be appreciated.
>
> Thanks.
