Powershell - How to check if a set of users are members of certain groups.

General idea: create a string with all your users, then call a function to check the membership and react for each one of them.

Here is a topic on array initialization with strings and going through it using a for loop: http://get-powershell.com/post/2008/02/07/Powershell-function-New-Array.aspx

Here is a topic on how to check user membership in a group: http://social.technet.microsoft.com/Forums/scriptcenter/en-US/1e75ab95-fd52-4eb5-a1c3-136d14050b63/check-if-specific-user-is-member-of-specific-group

There are many more articles on the topics in google, so you just need to combine several to reach your solution.

What type of result file are you looking for? Do you need to report each group membership status (True false against each group) or just report if they are missing any group? or do you need to add them to group if they are missing the group membership?

See if this works for you:

$Groups = Get-Content C:\GroupsList.txt
$Users = Get-Content C:\UserList.txt

$MembersArray = @()

foreach ( $User in $Users ) {
        foreach ( $Group in $Groups ) {

            $memberOf = Get-QADMemberOf -Identity $User -Name $Group

            if($memberOf)
            {
                $MembersArray += $User
            }
         
        }
        
}


$MembersArray | Export-CSV C:\ListOfMembers.csv -NoType
