powershell export group membership multiple job titles - powershell

Question

I have a csv with below eachother multiple job titles so like this:
Job title 1
Job title 2
Job title 3
What I now need is to export the group memberships of the user that has that job title so for example a person with job title 1 has a couple of group memberships. I need those group memberships  in a csv. Is it possible to do this automaticly for my whole csv that it does all the job title one by one?
I have this:
Get-ADUser -Filter {title -Like "Medior Functioneel beheerder"} | Get-ADPrincipalGroupMembership | select name
How do I get it so it only does this for one match since we have multiple users with the same job title but I only need it for one user. And how do I export this to an csv preferably on one line. for each job title.

Answer 1

I'd approach it like this:
For each job title:
Retrieve all users with their memberOf values
Select all distinct memberships
Output a custom object with title + list of memberships
Export custom objects to CSV
$csv = #'
Title
Job title 1
Job title 2
Job title 3
'# |ConvertFrom-Csv # you'd use `Import-Csv` here instead
$result = foreach($row in $csv){
# Fetch all relevant users with their `memberOf` attribute value
$Users = Get-ADUser -Filter "title -eq '$($row.Title)'" -Properties memberOf
# Select all distinct memberOf values
$Memberships = $Users.memberOf |Sort -Unique
# Resolve the group names
$GroupNames = ($Memberships |Get-ADGroup).Name
# Output custom object
[pscustomobject]#{
Title = $row.Title
Groups = $GroupNames -join ';'
}
}
# output to CSV
$result |Export-Csv -Path .\output.csv
