AD Tool/Script Populate Security Groups Automatically

Looking for a simplistic tool/script to auto populate Security Group(s) in AD.

So the tool/script scans each User and if a particular Security Group(s) isn't in their Member of List, it gets populated.
Obviously need this run automatically every few days

There are a few variations on this theme you might use. It uses the MS ActiveDirectory PowerShell module. Searches for everyone who isn't in the group, and adds them.
Get-ADUser -Filter { memberOf -ne 'CN=yourgroup,OU=somewhere,DC=domain,DC=local } | ForEach-Object {
    Add-ADGroupMember -Identity yourgroup -Member $_.DistinguishedName
}

Open in new window

The search might be a bit more constrained than that of course.

You've stripped out "{" characters all over the place. They're not there as decoration.
Apologies, I didn't see the full script.

It is now working but has removed all users from this particular Security Group!!
