Get All of a User’s Group Memberships with PowerShell

<# .SYNOPSIS Gets all the Active Directory groups that have a specified user, computer, group, or service account. .DESCRIPTION Gets all the Active Directory groups that have a specified user, computer, group, or service account. Unlike the built-in Get-ADPrincipalGroupMembership cmtlet, the function I've provided below will perform a recursive search that will return all of the groups that the account is a member of through membership inheritance. This function required the Active Directory module and thus must be run on a domain controller or workstation with Remote Server Administration Tools. .PARAMETER dsn The distinguished name (dsn) of the user, computer, group, or service account. .PARAMETER groups An array of ADObject instances for each group in which the user, computer, group, or service account is a member. This parameter can be ignored and in fact should never be specified by the caller. The groups parameter is used internally to track groups that have already been added to the list during recursive function calls. .NOTES Author : Brian Reich <breich@reich-consulting.net .LINK http://www.reich-consulting.net #> function Get-ADPrincipalGroupMembershipRecursive( ) { Param( [string] $dsn, [array]$groups = @() ) # Get an ADObject for the account and retrieve memberOf attribute. $obj = Get-ADObject $dsn -Properties memberOf # Iterate through each of the groups in the memberOf attribute. foreach( $groupDsn in $obj.memberOf ) { # Get an ADObject for the current group. $tmpGrp = Get-ADObject $groupDsn -Properties memberOf # Check if the group is already in $groups. if( ($groups | where { $_.DistinguishedName -eq $groupDsn }).Count -eq 0 ) { $groups += $tmpGrp # Go a little deeper by searching this group for more groups. $groups = Get-ADPrincipalGroupMembershipRecursive $groupDsn $groups } } return $groups } # Simple Example of how to use the function $username = Read-Host -Prompt "Enter a username" $groups = Get-ADPrincipalGroupMembershipRecursive (Get-ADUser $username).DistinguishedName $groups | Sort-Object -Property name | Format-Table
