I have a list of folks and their DN from AD (I do not have direct access to that AD). Their DNs are in format:
$DNList = \'CN=Bob Dylan,OU=Users,OU=Dept,OU=
You have 7 items per user, comma separated and you want rid of the first one.
So, split each item in the array using commas as the delimiter, return matches 1-6 (0 being the first item that you want to skip), then join with commas again e.g.
$DNList = $DNList|foreach{($_ -split ',')[1..6] -join ','}
If you then enter $DNList
it returns
OU=Users,OU=Dept,OU=Agency,OU=NorthState,DC=myworld,DC=com
OU=Contractors,OU=Dept,OU=Agency,OU=NorthState,DC=myworld,DC=com
OU=Users,OU=Dept,OU=Agency,OU=WaySouth,DC=myworld,DC=com
