Get-ADUser not functioning correctly

I've created a script that lists all users in a OU that are NOT a member of a certain group. This saves the results into a text file. I thought this was working fine until I took a username from the text file and searched it in Active Directory. Turned out the user was a member of the group I was trying to filter out. Here is the code - 

Get-ADUser  -SearchBase "OU=Users 2004,OU=Cyngor,DC=gwynedd,DC=rhwydwaith"  -Filter {( memberof -ne "CN=CTX AppSense,OU=Rheoli,OU=Grwpiau,OU=TC Enviroment,DC=gwynedd,DC=rhwydwaith")}  -Properties Name | select Name  | Export-CSV "C:\Users.txt"

I can't figure out why this isn't working correctly. Any suggestions out there?

Thanks.

memberOf is a multi-valued attribute, i.e. a list of distinguished names. Use the -notcontains operator to check if does not contain a particular distinguished name:

$ou = 'OU=Users 2004,OU=Cyngor,DC=gwynedd,DC=rhwydwaith'
$dn = 'CN=CTX AppSense,OU=Rheoli,OU=Grwpiau,OU=TC Enviroment,DC=gwynedd,DC=rhwydwaith'

Get-ADUser -Filter * -SearchBase $ou -Properties Name, MemberOf |
  ? { $_.MemberOf -notcontains $dn } |
  select Name  |
  Export-Csv 'C:\Users.txt' -NoType

Note that a user's primary group is not listed in the memberOf attribute. If the code should also handle primary groups you need to add a check for that:

$ou = 'OU=Users 2004,OU=Cyngor,DC=gwynedd,DC=rhwydwaith'
$dn = 'CN=CTX AppSense,OU=Rheoli,OU=Grwpiau,OU=TC Enviroment,DC=gwynedd,DC=rhwydwaith'

Get-ADUser -Filter * -SearchBase $ou -Properties Name, MemberOf |
  ? { $_.MemberOf -notcontains $dn -and $_.PrimaryGroup -ne $dn } |
  select Name  |
  Export-Csv 'C:\Users.txt' -NoType
