Change output results in PowerShell - string

Question

I want to get all user ID's with a specific token assigned.
It looks like this now when I run my script..
Get-ADUser -Filter * -Properties * | Select-Object vasco-LinkUserToDPToken, displayname
#Output#
vasco-LinkUserToDPToken Displayname
{CN=VES0423061,OU=br... User X
{} User X
{} User X
{CN=0067511310,OU=br... User X
{CN=0067077717,OU=br... User X
Example of a full vasco-LinkUserToDPToken :
{CN=VES0976944,OU=Internal Users,DC=mgm,DC=agf,DC=be}
the thing is I only want to filter VES + it should be shown like this (not containing empty strings or tokens that are not starting with VES):
VES0423061 User X

It looks like your property 'vasco-LinkUserToDPToken' is a multivalued property type (string array) of which you need to extract the DN inside.
You could try:
Get-ADUser -Filter "vasco-LinkUserToDPToken -like 'CN=VES*'" -Properties 'vasco-LinkUserToDPToken', DisplayName |
Select-Object #{Name = 'vasco-LinkUserToDPToken'; Expression = {
($_.'vasco-LinkUserToDPToken' | Where-Object {$_ -match '^CN=VES.*'}) -replace '.*(VES[^,]+).*', '$1'}
}, DisplayName
P.S. It is always a bad idea to use -Properties * is what you are after is just two properties. Using * forces to pull down ALL properties which is a waste of time
If the -Filter doesn't work on this custom property, you can always use a Where-Object clause afterwards like:
Get-ADUser -Filter * -Properties 'vasco-LinkUserToDPToken', DisplayName |
Where-Object { $_.'vasco-LinkUserToDPToken' -like 'CN=VES*' } |
Select-Object #{Name = 'vasco-LinkUserToDPToken'; Expression = {
($_.'vasco-LinkUserToDPToken' | Where-Object {$_ -match '^CN=VES.*'}) -replace '.*(VES[^,]+).*', '$1'}
}, DisplayName
