How can I get a list of all disabled domain users with group membership, one user per line, but omit results for users that have no membership?

For example, when our users are terminated, we need to remove all groups. I want to check for groups still connected to user, but not show the users where the groups are removed.

I have the following, which shows all disabled users, but can't figure out how to test for a null group. Any help would be appreciated.

Import-Module Activedirectory
Get-ADUser -Filter 'enabled -eq $false' -Properties DisplayName,memberof | % {
New-Object PSObject -Property @{
UserName = $_.DisplayName
Groups = ($_.memberof | Get-ADGroup | Select -ExpandProperty Name) -join 
","}
} | Select UserName,Groups

Add a where check before the select:

| Where-Object {$_.Groups -ne $null} 


Import-Module Activedirectory
Get-ADUser -Filter 'enabled -eq $false' -Properties DisplayName,memberof | % {
    New-Object PSObject -Property @{
    UserName = $_.Name
    Groups = ($_.memberof | Get-ADGroup | Select -ExpandProperty Name) -join ","}
} | Where-Object {$_.Groups -ne $null} | Select UserName,Groups
