How to get all groups that a user is a member of?

Question

PowerShell\'s Get-ADGroupMember cmdlet returns members of a specific group. Is there a cmdlet or property to get all the groups that a particular user is a member of?

Studying all comments presented gave me a starting point (thanks for such) but left me with several unresolved issues. As result here is my answer. The code snippet provided does a little more than what is asked for but it provides helpful debugging info.

[array] $script:groupsdns = @()
function Get-ADPrincipalGroupMembershipRecursive() 
{
  Param( [string] $dn, [int] $level = 0, [array] $groups = @() )

  #if(($groupsdns | where { $_.DistinguishedName -eq $dn }).Count -ne 0 ) { return $groups } # dependency on next statement
  #$groupsdns += (Get-ADObject $dn -Properties MemberOf) # Get-ADObject cannot find an object with identity
  if ($script:groupsdns.Contains($dn)) { return $groups }
  $script:groupsdns += $dn
  $mo = $Null
  $mo = Get-ADObject $dn -Properties MemberOf # Get-ADObject cannot find an object with identity
  $group = ($dn + " (" + $level.ToString())
  if ($mo -eq $Null) { $group += "!" }
  $group += ")"
  $groups += $group
  foreach( $groupdn in $mo.MemberOf )
  {
    $groups = Get-ADPrincipalGroupMembershipRecursive -dn $groupdn -level ($level+1) -groups $groups
  }
  if ($level -le 0) 
  { 
    $primarygroupdn = (Get-ADUser -Identity $dn -Properties PrimaryGroup).PrimaryGroup 
    $groups = Get-ADPrincipalGroupMembershipRecursive -dn $primarygroupdn -level ($level+1) -groups $groups
  }
  return $groups
}
$adusergroups = Get-ADPrincipalGroupMembershipRecursive -dn $aduser.DistinguishedName
$adusergroups | ft -AutoSize | `
