PowerShell eDirectory Group Membership Query

I found my self needing to query eDirectory for all the group objects and their members.  Below is the PowerShell script to accomplish this.  At its core, it is an LDAP query.

$ldapAssembly = [System.Reflection.Assembly]::LoadWithPartialName("System.DirectoryServices.Protocols");

function ldapQuery() {
    $eDirConnect = New-Object System.DirectoryServices.Protocols.LDAPConnection "$hostName";
    $eDirConnect.AuthType = [System.DirectoryServices.Protocols.AuthType]::Basic;
    $password = Read-Host -Prompt "Password" -AsSecureString;
    $queryCreds = New-Object "System.Net.NetworkCredential" -ArgumentList $authUser,$password;
    $scope = [System.DirectoryServices.Protocols.SearchScope]::subtree;
    $attrs = $Null;
    $query = New-Object System.DirectoryServices.Protocols.SearchRequest -ArgumentList $basedn,$filter,$scope,$attrs;
    $eDirData = $eDirConnect.SendRequest($query);
    $eDirEntries = $eDirData.Entries;

$eDirGroupData = ldapQuery -hostName "YoureDirServer" -authUser "cn=user,o=edir" -basedn "" -filter "(objectClass=Group)";

foreach ( $entry in $eDirGroupData ) {
    $groupCN = $entry.Attributes.cn[0];
    if ( $entry.Attributes.AttributeNames -contains "groupmember" ) {
        $memberCount = $entry.Attributes.groupmember.count;
        while ( $i -lt $memberCount ) {
            $groupMember = $entry.Attributes.groupmember[$i];
            write-output "$groupCN,$groupMember";
     } else {
         write-output "$groupCN";
